Mapping Mountains - Significant Name Changes - 200m Twmpau


200m Twmpau – Significant Name Changes

The 200m Twmpau (thirty welsh metre prominences and upward) are the Welsh hills at or above 200m and below 300m in height that have a minimum drop of 30m.  Accompanying the main P30 list is a sub list entitled the 200m Sub-Twmpau with the qualification to this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop.

The list is authored by Myrddyn Phillips and the posts that have appeared on Mapping Mountains detailing the significant name changes to the main P30 list and the sub list appear below presented chronologically in receding order.

Grogwynion (SN 720 725) - 70th significant name change

Survey post for Grogwynion

 

There has been a Significant Name Change to a hill that is listed in the 200m Twmpau, with the summit height, bwlch height and their locations, the drop and status of the hill derived from LIDAR analysis and a subsequent Trimble GeoXH 6000 survey conducted by Myrddyn Phillips. 

Grogwynion (SN 720 725)

The criteria for the list that this name change applies to are: 

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward. 

The 200m Twmpau by Myrddyn Phillips

The hill is adjoined to the Elenydd group of hills, which are situated in the central part of the Mid and West Wales Region (Region B, Sub-Region B2), and is positioned with minor roads to its north-east, north and south, and has the B4343 road to its east, and the village of Pont-rhyd-y-groes towards the east. 

Extract from the Ordnance Survey 1:25,000 Explorer map

When the original 200m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was listed under the name of Castell Graigwynion, which was a typo for Castell Grogwynion which is a prominent name that appears near the summit of this hill on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map.

This was one of a number of hills visited during the day and I approached it from the north calling at the farm of Pengrogwynion, which is positioned directly under the hill to its north-east.  The front door was opened by Wendy Croket, I introduced myself and explained my interest in upland place-names and in particular the hill above the farm.  We talked at length and she told me about the ancient fortifications and after asking permission to visit, she kindly told me the best way up.  During the conversation she told me that the name of the hill is Grogwynion with the word Castell purely signifying the ancient hill fort as being the castle of the hill of Grogwynion.  We were soon joined by Caredig, who I then later met when descending from my last hill of the day.

Therefore, the name this hill is now listed by in the 200m Twmpau is Grogwynion, and this was derived from local enquiry.

The hill appeared in the original 200m Welsh P30 list on Geoff Crowder’s v-g.me website under the invented and transposed name of Pen y Hafod Seller, with an accompanying note stating; Name from buildings to the South-East.


Pen y Hafod Seller260cSJ137066125215/239Name from buildings to the South-East

 

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them or as in this instance transpose the name of a farm and prefix it with the words Pen y.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found. 

Extract from the Ordnance Survey 1:25,000 Explorer map

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map.  The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act.  This act allowed tithes to be paid in cash rather than goods.  The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.  This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales. 

Extract from the Tithe map

The enclosed land where the summit of this hill is situated is given the number 788 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land.  The land where the summit of this hill is situated is named as Cae Coch, with the details on the Tithe map appearing in the parish of Castle Caereinion and in the county named as Montgomery.

Therefore, the name this hill is now listed by in the 200m Twmpau is Cae Coch, and this was derived from the Tithe map.

When I first visited this hill in June 2011 I called at Mount Farm (SJ 190 040) and met Peter Holloway.  Peter is local to the area and has farmed from Mount Farm all of his life.  I asked about the names of a number of local hills and for this hill he told me that he knows it as Llwynderw Hill.

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward. 

The 200m Twmpau by Myrddyn Phillips

The hill is adjoined to the Elenydd group of hills which are situated in the central part of the Mid and West Wales Region (Region B, Sub-Region B2), and it is positioned with the B4576 road to its west and minor roads to its south-east and east, and has the village of Llangwyryfon towards the south. 

The hill appeared in the original Welsh 200m P30 list on Geoff Crowder’s v-g.me website under the transposed name of Penbryn, with an accompanying note stating; Name from buildings to the West.

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them or as in this instance transpose the name of a near farm and use it for that of the hill.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found. 

Extract from the Ordnance Survey 1:25,000 Explorer map

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map.  The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act.  This act allowed tithes to be paid in cash rather than goods.  The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.  This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales. 

Extract from the Tithe map

The enclosed land where the summit of this hill is situated is given the number 95 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land.  The land where the summit of this hill is situated is named as Banc, with the details on the Tithe map appearing in the parish of Llangwyryfon and in county named as Cardigan. 

Extract from the apportionments

Therefore, the name this hill is now listed by in the 200m Twmpau is Banc and this was derived from the Tithe map.

This was one of a number of hills visited during the day and I approached it via a narrow paved road that ends at the farm of Penlan, from here a track continued in the same direction toward the farm of Tynbwlch. 

Walking along the track toward the hill a quad bike appeared from an adjacent field and I flagged it down.  I introduced myself to Joseph Cook, who along with his father farms this land.  I explained my interest in his hill and its name.  Joseph told me that they know it as Banc, and happy with another name documented I thanked him, asked permission to visit the summit, which was duly granted with Joseph kindly directing me toward the best ascent route using connecting gates through the various fields toward the summit of the hill.

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them or as in this instance transpose the name of near wood and add the word Top to it.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found. 

Extract from the Ordnance Survey 1:25,000 Explorer map

Since publication of these P30 lists on Geoff Crowder’s v-g.me website there have been a number of Ordnance Survey maps made available online, some of these are historic such as the series of Six-Inch maps on the National Library of Scotland website, whilst others are current and digitally updated such as the old Vector Map Local hosted on the Geograph website and which was entitled the Interactive Coverage Map.  One of the historic maps now available is the Ordnance Survey One-Inch ‘Old Series’ map and it is this map that formed the basis for the change in this hill’s listed name. 

Extract from the Ordnance Survey One-Inch 'Old Series' map

The One-Inch ‘Old Series’ map was the first map that Ordnance Survey produced, and their publication culminated from the whole of Britain being surveyed between 1791 and 1874 and the detail gathered therein produced at a scale of one inch to the mile and published in sheet format between 1805 and 1874.  The One-Inch ‘Old Series’ maps for the whole of Wales are now available online; they are also available in map format as enlarged and re-projected versions to match the scale and dimensions of the Ordnance Survey 1:50,000 Landranger series and are published by Cassini.  This series of maps form another important part in the study of Welsh upland place-names and bridge the timeframe leading up to the production of the Ordnance Survey base map of the Six-Inch series, and importantly for this hill and its listed name, it is the One-Inch ‘Old Series’ map and the series of Six-Inch maps that names the area taking in the summit of this hill as Parkhouse Rocks. 

Extract from the Ordnance Surveys series of Six-Inch maps

Therefore, the name this hill is now listed by in the 200m Twmpau is Parkhouse Rocks, and this was derived from the Ordnance Survey One-Inch ‘Old Series’ map and the Ordnance Survey series of Six-Inch maps.

Mynydd Cefn Maes Mawr (SN 728 985) - 55th significant name change

Hill Reclassifications post for Mynydd Cefn Maes Mawr

 

There has been a Significant Name Change to a hill that is listed in the 200m Twmpau, with the summit height, bwlch height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips. 

LIDAR image of Mynydd Cefn Maes Mawr (SN 728 985)

The criteria for the list that this name change applies to are: 

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward. 

The 200m Twmpau by Myrddyn Phillips

The hill is adjoined to the Banc Llechwedd Mawr group of hills, which are situated in the north-western part of South Wales (Region B, Sub-Region B1), and it is positioned with the A487 road to its north-west and minor roads to its south and east, and has the town of Machynlleth towards the north-east. 

The hill appeared in the original Welsh 200m P30 list on Geoff Crowder’s v-g.me website under the name of Mynydd Cae-du, which is a prominent name that appears on the contemporary Ordnance Survey 1:25,000 Explorer map close to the summit of this hill.


Mynydd Cae-du220cSN72898513523


During my early hill listing I paid little regard to name placement on the map, or the meaning of names and to what feature the name was appropriately applied to.  Therefore I prioritised names for listing purposes that I now understand are either inappropriate or where another name is viewed as being more appropriate. 

Extract from the Ordnance Survey 1:25,000 Explorer map

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map.  The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act.  This act allowed tithes to be paid in cash rather than goods.  The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.  This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales. 

Extract from the Tithe map

The enclosed land where the summit of this hill is situated is given the number 1055 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land.  The land where the summit of this hill is situated is named as the Sheepwalk for the farm of Cefnmaesmormawr, with the sheepwalk being the cynefin, or mountain land of this farm.  In instances like this it is appropriate to use the farm name preceded by the word Mynydd, as in Mynydd Cefn Maes Mawr.  This is also in keeping with other examples for adjacent land, such as Mynydd Cae Du and Mynydd Garth Gwynion, both of which are the cynefin, or mountain land of the farms of Cae-du and Garth-gwynion respectively.  The details on the Tithe map appear in the parish of Machynlleth and in the county named as Montgomery.

Extract from the apportionments

Therefore, the name this hill is now listed by in the 200m Twmpau is Mynydd Cefn Maes Mawr, and this was derived from the Tithe map.

The 200m Twmpau by Myrddyn Phillips

The hill is adjoined to the Carnedd Wen group of hills which are situated in the south-eastern part of North Wales (Region A, Sub-Region A4), and it is positioned with the B4390 road to its north, the B4389 road to its south and the A483 road to its east, and has the village of Betws Cedewain towards the south. 

When the original 200m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was not included in the accompanying Hills to be surveyed sub list, as it was considered not to meet the criteria then used for this sub category. 

When the sub list was standardised, and interpolated heights and drop values also included the details for this hill were re-assessed and it was listed under the point (Pt. 214m) notation with 20m of drop, based on the 214m summit spot height that appears on the Ordnance Survey 1:25,000 Explorer map, and the 194m bwlch spot height that appeared on the Ordnance Survey Vector Map Local that was hosted on the Geograph website and which was entitled the Interactive Coverage Map. 

Extract from the Ordnance Survey 1:25,000 Explorer map

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map.  The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act.  This act allowed tithes to be paid in cash rather than goods.  The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.  This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.

This was one of a number of hills on a circular walk and after visiting the summit I called at Penyffridd to make place-name enquiries.  I was met by Gareth Jones and his daughter Katie.  Having explained my interest in hill and field names Gareth told me that he had lived here all his life and celebrated his 72nd birthday the day before, and that the farm had been in his family for over 100 years.  We then discussed the merits of the name he knows the high field where the summit of this hill is situated; Field Above The House, Gareth also told me that the hill does not have an individual name.  The conversation progressed to other subjects and after ten minutes or so he asked if I wanted a drink.  Soon afterward I was sitting in his conservatory with nibbles prepared by his wife; Glenys, who also served up a large mug of very welcome tea.  I spent about an hour in the company of Gareth, chatting and laughing until the cake that was then served filled me up and I joked that if I didn’t leave soon I’d be getting back to my car when it was dark.

When the original 200m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was not included in the accompanying Hills to be surveyed sub list, as it was considered not to meet the criteria then used for this sub category.  

After the sub list was standardised, and interpolated heights and drop values also included the details for this hill were re-assessed and it was listed under the point (Pt. c 216m) notation with an estimated c 20m of drop, based on an estimated c 216m summit height and the 196m bwlch spot height that appeared on the Ordnance Survey Vector Map Local hosted on the Geograph website and which was named the Interactive Coverage Map.

When visiting this hill I met Paul Marsh on the lane leading toward it.  Paul rents the land where the summit of this hill is situated and told me that he had never heard an individual name for the hill, and although he knew the uppermost field as Coed y Perthi or Alan’s Land, he advised me to call at the red bricked house further up the lane as Alan Jones who owns the land would no doubt know the proper field name. 

Paul Marsh

The two names Paul gave me relate to the house between where I met Paul and Alan Jones’s house, this is marked by the same name on Ordnance Survey 1:25,000 maps; Coed y Perthi.  The second name relates to the person who owns the land; Alan’s Land. 

Thanking Paul I asked permission to visit the hill, which was duly granted, and continued up the lane and after surveying the summit, called at Alan Jones’s house.  He was out, but his son; Ryan was extremely helpful.  I explained my interest in place-names and as we were standing outside I pointed toward the top of the field that I had just visited and surveyed.  Ryan told me that the field where the summit of this hill is situated is known as Sixteen Acres. 

Ryan Jones

Therefore, the name this hill is now listed by in the 200m Twmpau is Sixteen Acres, and this was derived from local enquiry.

The criteria for the list that this name change applies to are: 

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward. 

The 200m Twmpau by Myrddyn Phillips

The hill is adjoined to the Carnedd Wen group of hills which are situated in the south-eastern part of North Wales (Region A, Sub-Region A4), and it is encircled by minor roads, with also the A458 road to its north, the A470 road to its south-west and the B4389 road to its east, and has the village of Adfa towards the south south-west. 

When the original 300m height band of Welsh P30 hills was published on Geoff Crowder’s v-g.me website, this hill was included in the main P30 list and listed with a 300m summit height, based on the spot height that appears on the Ordnance Survey 1:25,000 Explorer map and listed by the name of Dwyrhiw, which is a prominent name that appears to the south-east of the summit on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map.

During my early hill listing I paid little regard to name placement on the map, or the meaning of names and to what feature the name was appropriately applied to.  Therefore, I prioritised names for listing purposes that I now understand are either inappropriate or where another name is viewed as being more appropriate.

Five weeks after surveying the summit of this hill I re-visited with Alex Cameron.  This second visit gave opportunity to call at the landowning farm (SO 069 030) which is situated just below the end of the track which is adjacent to the summit and to its south.  I’d already been told by Ruth Davies of Llawnt Isaf (SJ 077 033) that John Watkins would be able to help and no doubt give me the field name for where the summit is situated.  John answered the door and we talked for 10-15 minutes.  He explained that his father came to the farm as a tenant in 1917 and then bought the farm from the local estate in 1921 when the estate was sold.  I drew a diagram of the farm and the access track leading from it to the paved lane, and the fields and their boundaries.  John told me that the field where the summit is situated is known as the Square Field and this was once made up of two fields, with the one nearer the paved road being known as the Clover Field.  Each is now a part of Square Field, and the field where the 300m spot height appears on the Ordnance Survey 1:25,000 Explorer map is known as the Meadow.

Before visiting this hill I called at Llawnt Isaf (SJ 077 033), the farm directly below the hill to its west.  As there was no answer I continued toward the hill and soon met the local farmer; Ruth Davies, who was heading back to her farm in a vehicle.  I flagged her down and we talked for ten minutes or so.  Ruth told me that the farm had been in her family since her parents moved here, with both being local with her father from Aberhafesp and her mother from Manafon.  Ruth is now aged 74 and when I enquired about the upper field where the summit of this hill is situated she told me that the two upper fields are known as the Pastures and that this name was passed down to her from her father.  She also confirmed that this hill has no individual name.

Mapping Mountains - Significant Name Changes - 200m Twmpau

Cae Cefn TÅ· (SN 416 535) - 46th significant name change

 

There has been a Significant Name Change to a hill that is listed in the 200m Twmpau, with the summit height, bwlch height and their locations, the drop and status of the hill derived from detail on contemporary and historical maps produced from Ordnance Survey data.  This was initiated by Joe Nuttall who produced a summit analysis programme, and then by evaluation conducted by Jim Bloomer and subsequently by Myrddyn Phillips.

The criteria for the list that this name change applies to are:

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

The 200m Twmpau by Myrddyn Phillips

The hill is adjoined to the Hafod Ithel group of hills which are situated in the western part of Mid and West Wales (Region B, Sub-Region B2), and it has the A487 road to its north-west, the B4338 road to its south-west and minor roads to its south-east and its north-east, and has the town of Ceinewydd (New Quay) towards the north north-west.

When the original 200m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was not included in the accompanying Hills to be surveyed sub list, as it was considered not to meet the criteria then used for this sub category. 

When the sub list was standardised, and interpolated heights and drop values also included the details for this hill were re-assessed and it was listed under the point (Pt. 289m) notation with an estimated c 25m of drop, based on the 289m summit spot height that appears on the Ordnance Survey 1:25,000 Explorer map and an estimated c 264m bwlch height, with the latter based on interpolation of 5m contouring between 260m – 265m.

Extract from the Ordnance Survey 1:25,000 Explorer map

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map.  The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act.  This act allowed tithes to be paid in cash rather than goods.  The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.  This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.

Extract from the Tithe map

The enclosed land where the summit of this hill is situated is given the number D246 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land.  The land where the summit of this hill is situated is named as Cae Cefn TÅ·, with the details on the Tithe map appearing in the parish of Llan-arth and in the county named as Cardigan.

Extract from the apportionments

Therefore, the name this hill is now listed by in the 200m Twmpau is Cae Cefn TÅ·, and this was derived from the Tithe map.

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them or as in this instance use the translation of the word settlement which appears in ancient script on the Ordnance Survey 1:25,000 Explorer map and prefix it with the words Pen y.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

Extract from the Ordnance Survey 1:25,000 Explorer map

After surveying the summit of this hill I called at Llwyncopa which is an old farm now renovated as a private residence and met James Thomas.  James is aged 67 and has lived in Llwyncopa for ten years and is local to the area.  This hill is prominently positioned behind James’ house and without hesitation he told me it is known as Pen y Gaer.  This name was not a surprise as the hill has an ancient hill fort encircling its summit and the term Pen y Gaer is used for many such ancient Welsh settlements.  

Therefore, the name this hill is now listed by in the 200m Twmpau is Pen y Gaer, and this was derived from local enquiry.

The enclosed land where the summit of this hill is situated is given the number C110a on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land.  The land where the summit of this hill is situated is named as Crasty Frain, with the details on the Tithe map appearing in the parish of Tregynon and in the county named as Montgomery.

Extract from the apportionment

Therefore, the name this hill is now listed by in the 200m Twmpau is Crasty Frain, and this was derived from the Tithe map.

There has been a Significant Name Change to a hill that is listed in the 200m Twmpau, with the summit height, bwlch height and their locations, the drop and status of the hill confirmed by LIDAR analysis conducted by Myrddyn Phillips.

LIDAR image of Church Hill Common (SO 517 105)

The criteria for the list that this name change applies to are:

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

The hill is adjoined to the Gwent Is Coed group of hills which are situated in the south-eastern part of South Wales (Region C, Sub-Region C3), and it is positioned with the B4293 road and the A40 road to the west and the A466 road and the Afon Gwy (River Wye) to the east, and has the town of Trefynwy (Mounmouth) towards the north-west.

When the original 200m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was listed under the name of Troypark Wood Top, with an accompanying note stating; Name from wood to the West.


Troypark Wood Top232mSO51810616214Name from wood to the West


During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them or as in this instance transpose the name of a wood and add the word Top to it.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

Extract from the Ordnance Survey 1:25,000 Explorer map

As the name Church Hill Common appears close to this hill’s summit on the contemporary Ordnance Survey 1:25,000 Explorer map, the land boundary of this common was examined on the Tithe map, and at the time of the Tithe the summit of this hill was situated on land associated with this common.

Therefore, the name this hill is now listed by in the 200m Twmpau is Church Hill Common, and this name was derived from the Ordnance Survey 1:25,000 Explorer map with the Tithe map confirming the summit position at the time of the Tithe to be situated on land associated with this common.

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them or as in this instance transpose the name of what is probably a farm and use it for that of the hill.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

Mapping Mountains - Significant Name Changes - 200m Twmpau

Mynydd Llwyd (ST 433 935) - 39th significant name change

Significant Height Revisions post for Mynydd Llwyd


There has been a Significant Name Change to a hill that is listed in the 200m Twmpau and Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height, their locations, the drop, dominance and status of the hill derived from detail on contemporary and historic Ordnance Survey maps.

The criteria for the two listings that this name change applies to are:

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau, with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

Y Trechol - The Dominant Hills of Wales - Welsh P30 hills whose prominence  equal or exceed half that of their absolute height.  With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose prominence is between one third and half that of their absolute height, with the Introduction to the Mapping Mountains publication of this list appearing on the 3rd December 2015, and which is now available in its entirety on Mapping Mountains in Google Doc format.

The hill is adjoined to the Gwent Is Coed group of hills which are situated in the south-eastern part of South Wales (Region C, Sub-Region C3), and it is positioned with the A449 road to its west, the A48 road to its south and the B4235 road to its north-east, and has the city of Casnewydd (Newport) towards the west south-west.

Extract from the Ordnance Survey 1:25,000 Explorer map

The hill appeared in the original 200m Welsh P30 list on Geoff Crowder’s v-g.me website under the name of Gray Hill, which is a name that appeared near the summit of this hill on Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps of the day.


Gray Hill273mST434935171/17214275m on 1986 1:50000 map


Since publication of these P30 lists on Geoff Crowder’s v-g.me website there have been a number of Ordnance Survey maps made available online, some of these are historic such as the series of Six-Inch maps on the National Library of Scotland website, whilst others are current and digitally updated such as the Vector Map Local that used to be hosted on the Geograph website and which is named the Interactive Coverage Map.  Two of the historic maps now available are the Ordnance Survey Draft Surveyors map which formed the basis for the first publicly available Ordnance Survey One-Inch ‘Old Series’ map, and it is these maps that form the basis for the change in this hill’s listed name.

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Surveyor’s surveyors between the 1780s and 1840 and formed the basis for the first publicly available One-Inch map.  They were drawn at scales of six inches to the mile for areas considered of particular military significance and down to two inches to the mile for other areas.  Fair copies were then produced from these preliminary drawings to one inch to the mile and then copper plates were prepared for printing.  The Draft Surveyors maps for the whole of Wales are now available online and they form an important part in the study of Welsh upland place-names as they bridge the time frame between the late 18th century and the mid-19th century when the Ordnance Survey produced their first One-Inch maps, and importantly for this hill and its listed name, this map gives the Welsh version, along with its English counterpart.

Extract from the Ordnance Survey Draft Surveyors map

The One-Inch ‘Old Series’ map was the first map that Ordnance Survey produced, and their publication culminated from the whole of Britain being surveyed between 1791 and 1874 and the detail gathered therein produced at a scale of one inch to the mile and published in sheet format between 1805 and 1874.  The One-Inch ‘Old Series’ maps for the whole of Wales are now available online; they are also available in map format as enlarged and re-projected versions to match the scale and dimensions of the Ordnance Survey 1:50,000 Landranger series and are published by Cassini.  This series of maps form another important part in the study of Welsh upland place-names and bridge the timeframe leading up to the production of the Ordnance Survey base map of the Six-Inch series, and again, this map gives the Welsh version of this name; Mynydd Llwyd, along with its English counterpart.

Extract from the Ordnance Survey One-Inch 'Old Series' map

The intricacies of language and prioritising one in favour of another for listing a hill is fraught with complication, with originating Cymraeg names being anglicised and also originating English names being cymricised, examples such as these are more common in border country and especially so for anglicised forms.  There is no steadfast rule that fits all, but as a standard a name that has its origins in the Welsh language should be prioritised in favour of a contemporary anglicised or English version of the name, and ideally for this to be substantiated by either historic documentation and / or contemporary usage.  Likewise, if a name exists where an element of it is in English and if this name applies to a hill that is situated in a Welsh speaking part of Wales it is standard practice to use a full Welsh term for the name.  It is also standard practice to use a Welsh name for a hill if another name exists that has originated in a different language.

Therefore, the name this hill is now listed by in the 200m Twmpau and Y Trechol – The Dominant Hills of Wales is Mynydd Llwyd, and this was derived from the Ordnance Survey Draft Surveyors map and the One-Inch ‘Old Series’ map, with the Welsh name for this hill prioritised over its English counterpart, which for listing purposes is standard practice.


The full details for the hill are:

Mapping Mountains - Significant Name Changes - 200m Twmpau

Hafod Mountain (SJ 211 630) - 38th significant name change

Survey post for Hafod Mountain


There has been a Significant Name Change to a hill that is listed in the 200m Twmpau, with the summit height and its location confirmed by a Trimble GeoXH 6000 survey conducted by Myrddyn Phillips on the 18th December 2019 and the bwlch height and its location, the drop and status of the hill derived from detail on contemporary Ordnance Survey maps.

The summit of Hafod Mountain (SJ 211 630)

The criteria for the list that this name change applies to are:

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

The hill is adjoined to the Moel y Gamelin group of hills, which are situated in the north-eastern part of North Wales (Region A, Sub-Region A2), and it is positioned with the A494 road to its south and minor roads to its west, north and east, and has the village of Gwernymynydd towards the south.

Extract from the Ordnance Survey 1:25,000 Explorer map

The hill appeared in the original 200m Welsh P30 list on Geoff Crowder’s v-g.me website under the partly invented and transposed name of Bryn Gwernymynydd, with an accompanying note stating; Name from village to the South.


Bryn Gwernymynydd285mSJ212631117265Name from village to the South


During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them or as in this instance use the name of a village and precede it with the word Bryn.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

After surveying the summit of this hill I called at a number of houses on my way back to my car and was directed toward Hafod Issa Parc Arthur farm and Jo Owen.  It is Jo who grazes sheep on the land where the summit of this hill is situated.

Jo Owen of Hafod Issa Parc Arthur farm

I was soon standing in the farm yard talking with Jo and having explained my interest in the hill and its name, she told me that her Grandmother moved to the area in 1938 and worked and lived at Plas Hafod (SJ 213 634).  We could see the upper part of the hill from the farm and Jo said that it’s known as Hafod Mountain and that a part of the hill that is farther over and lower is known as Hafod Moor and explained that when the lead mines were operating in the 1800s the hill was known as Mold Mountain.

Mapping Mountains - Significant Name Changes - 200m Twmpau

Cymin (SO 527 125) - 37th significant name change


There has been a Significant Name Change to a hill that is listed in the 200m Twmpau and Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height, their locations, the drop, dominance and status of the hill confirmed by LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the two listings that this name change applies to are:

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

Y Trechol - The Dominant Hills of Wales - Welsh P30 hills whose prominence  equal or exceed half that of their absolute height.  With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose prominence is between one third and half that of their absolute height, with the Introduction to the Mapping Mountains publication of this list appearing on the 3rd December 2015, and which is now available in its entirety on Mapping Mountains in Google Doc format.

The hill is adjoined to the Fforest y Ddena group of hills which are situated in the south-eastern part of South Wales (Region C, Sub-Region C3), and it is positioned with the A4136 road to its north and the A466 road to its south-west, and has the town of Trefynwy (Monmouth) towards the west.

The hill appeared in the original 200m Welsh P30 list on Geoff Crowder’s v-g.me website under the name of Kymin Tower, which is a name that appeared near the summit of this hill on Ordnance Survey 1:25,000 Outdoor Leisure maps of the day.


Kymin Tower250cSO52812416214


During my early hill listing I paid little regard to name placement on the map, or the meaning of names and to what feature the name was appropriately applied to.  Therefore I prioritised names for listing purposes that I now understand are either inappropriate or where another name is viewed as being more appropriate.  The name of Kymin Tower refers to an 18th century round house and naval temple that are positioned on the summit area of this hill, as these are inanimate objects a name that refers directly to the hill is more appropriate.

Extract from the Ordnance Survey 1:25,000 Explorer map

Contemporary Ordnance Survey maps use the name Kymin which is positioned near the summit of this hill.  This form of this name also appears in a number of online sources.  The word Kymin is anglicised from the Welsh word Cymin, meaning common or unenclosed land, with the definite article ‘Y’ lost as evidenced in the anglicised form (Place-names of Gwent, Richard Morgan, Gwasg Carreg Gwalch 2005).

The intricacies of language and prioritising one in favour of another for listing a hill is fraught with complication, with originating Cymraeg names being anglicised and also originating English names being cymricised, examples such as these are more common in border country and especially so for anglicised forms.  There is no steadfast rule that fits all, but as a standard a name that has its origins in the Welsh language and where this is substantiated by either historic documentation and / or contemporary usage should be prioritised in favour of a contemporary anglicised or English version of the name.  Likewise, if a name exists where an element of it is in English and if this name applies to a hill that is situated in a Welsh speaking part of Wales it is standard practice to use a full Welsh term for the name.  It is also standard practice to use a Welsh name for a hill if another name exists that has originated in a different language.

Therefore, the name this hill is now listed by in the 200m Twmpau and Y Trechol – The Dominant Hills of Wales is Cymin, and this was derived from the anglicised form that appears on contemporary Ordnance Survey maps.

Y Trechol - The Dominant Hills of Wales by Myrddyn Phillips

The hill is adjoined to the Mynyddoedd Duon group of hills which are situated in the eastern part of South Wales (Region C, Sub-Region C3), and it is positioned with the Afon Wysg (River Usk) and the B4598 road to its west, the A40 road to its north and the A449 road to its east, and has the village of Raglan towards the east north-east and the town of Brynbuga (Usk) towards the south south-east.

When the original 100m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was listed under the name of Clytha Hill, which is a prominent name that appears on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map close to what was thought to be the summit of this hill.

Extract from the Ordnance Survey 1:25,000 Explorer map

LIDAR analysis has relocated the summit position of this hill from a 196m point that was given as two spot heights that are positioned close to where the name of Clytha Hill appears on contemporary Ordnance Survey maps to a higher 201.4m summit positioned at SO 36613 06919.  This higher summit is situated in woodland that is named on the map as Coed y Bwnydd.  This name appears on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map and its position in relation to the summit of this hill is substantiated via the Ordnance Survey series of Six-Inch maps.
