Y Trichant – The 300m Hills of Wales – Significant Name Changes

 

Y Trichant – The 300m Hills of Wales – Significant Name Changes


Y Trichant - The 300m Hills of Wales are the Welsh hills at or above 300m and below 40om in height that have a minimum drop of 30m.  Accompanying the main P30 list is a sub list entitled the Sub-Trichant, with the qualification to this sub category being all Welsh hills at or above 300m and below 400m in height with 20m or more and below 30m of drop, with the Introduction to the re-naming of this list and its publication history appearing on Mapping Mountains on 13th May 2017.

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.

Pt. 323.6m (SN 987 839) - 260th significant name changes

Summit Relocations post for Pt. 323.6m

 

There has been a Significant Name Change to a hill that is listed in the Y Trichant – The 300m Hills of Wales, with the summit height, bwlch height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips.

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

Y Trichant – The 300m Hills of Wales – Welsh hills at or above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub list entitled the Sub-Trichant, with the criteria for this sub category being all Welsh hills at or above 300m and below 400m in height with 20m or more and below 30m of drop.  The list is authored by Myrddyn Phillips with the Introduction to the list and the renaming of it appearing on Mapping Mountains on the 13th May 2017, and the Introduction to the Mapping Mountains publication of the list appearing on the 1st January 2022. 

Y Trichant - The 300m Hills of Wales by Myrddyn Phillips

The hill is adjoined to the Hirddywel group of hills, which are situated in the northern part of South Wales (Region B, Sub-Region B2), and it is positioned with the A470 road to its north and minor roads to its west and east, and has the town of Llanidloes towards the west.

The hill appeared in the original 300m height band of Welsh P30 hills published on Geoff Crowder’s v-g.me website, under the transposed name of Pen-y-banc, with an accompanying note stating; Name from buildings to the North.


Pen-y-banc320cSN988840136214Name from buildings to the North


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 Pen, Bryn or Moel in front of them.  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

However, on occasion even when research is conducted an appropriate name for the hill may not be found, and on such occasions the listing protocol is to use the point (Pt. 323.6) notation, and for this hill this is such an example.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Pt. 323.6m, and this is being used as the author has not found an appropriate name for the hill either through historic research and/or local enquiry.

The hill is adjoined to the Hirddywel group of hills, which are situated in the northern part of South Wales (Region B, Sub-Region B2), and it is positioned with the A489 road to its north and minor roads to its south-west and south-east, and has the town of Y Drenewydd (Newtown) towards the east.

The hill appeared in the original 300m height band of Welsh P30 hills published on Geoff Crowder’s v-g.me website, under the transposed name of Cefn-nith, with an accompanying note stating; aka Penstrowed 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, with little consideration for the meaning of the name used and where it was appropriately applied to.  My preference was to use farm names and put Pen, Bryn or Moel in front of them or as in this instance transpose a prominent name that appears near the summit of this hill on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map.  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.

Since the original publication of the Welsh P30 lists on Geoff Crowder’s v-g.me website there have been a number of 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 were digitally updated such as the Ordnance Survey Vector Map Local that was hosted on the Geograph website and which was entitled the Interactive Coverage Map, whilst others are current and digitally updated such as the interactive mapping on the Magic Maps and WalkLakes websites, and it is the series of Ordnance Survey Six-Inch maps that form the basis of the change in the listed name of this hill. 

Extract from the Ordnance Survey series of Six-Inch maps

The Ordnance Survey series of Six-Inch maps formed the base map Ordnance Survey used for many decades leading to the production of the 1:10,000 Series of maps, both have now been superseded by the digitised Master Map.  The series of Six-Inch maps are excellent for name placement and especially so compared to the contemporary Ordnance Survey 1:25,000 Explorer map, and it is the series of Six-Inch maps as well as the contemporary Ordnance Survey 1:25,000 Explorer map that place the name of Cefn Lladron adjacent to the summit of this hill.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Cefn Lladron and this was derived from the contemporary Ordnance Survey 1:25,000 Explorer map and confirmed by the Ordnance Survey series of Six-Inch maps.

The hill is adjoined to the Mynydd Epynt group of hills, which are situated in the central part of South Wales (Region B, Sub-Region B1), and it is positioned encircled by minor roads, with the B4520 road farther to its west, the A470 road farther to its south, east and north-east, and has the town of Talgarth towards the east south-east.

When the original 300m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website, this hill was not included in the 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-evaluated and it was listed under the point (Pt. 347m) notation with an estimated c 20m of drop, based on the 347m summit spot height that appears on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map and an estimated c 327m bwlch height, based on interpolation of 10m contouring between 320m – 330m.

Extract from the Ordnance Survey Draft Surveyors map

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey 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, it is this map that places the name Mynydd Llandyfalle across what is now open access land and which takes in the summit of this hill.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Mynydd Llandyfalle and this was derived from the Ordnance Survey Draft Surveyors 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. 

Extract from the Tithe map

The enclosed land where the summit of this hill is situated is given the number 11 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 a part of Pen Rhiw Einon farm in the apportionments, with the details on the Tithe map appearing in the parish of Llandyfalle and in the county named as Brecon. 

Extract from the apportionments

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Pen Rhiw Einon and this was derived from the Tithe map.

Y Pedwarau – The 400m Hills of Wales – Welsh hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list are five categories of sub hills, with this hill listed in the 390m Sub-Pedwar category.  The criteria for this category are all Welsh hills at or above 390m and below 400m in height that have 30m minimum drop.  The list is co-authored byMyrddyn Phillips and Aled Williams and is published on Mapping Mountains in Google Doc format.

Y Pedwarau - The 400m Hills of Wales by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Mynydd Epynt group of hills, which are situated in the central part of South Wales (Region B, Sub-Region B1), and it is positioned with the B4519 road to its north-east and a minor road to its south, and has the small community of Capel Uchaf (Upper Chapel) towards the south-east.

The hill appeared in the original 300m height band of Welsh P30 hills compiled by Myrddyn Phillips and published on GeoffCrowder’s v-g.me website, under the invented and transposed name of Twyn y Mynachdy, with an accompanying note stating; Name from buildings to the West.


Twyn y Mynachdy398mSN996423147/160188Included by contour configuration. Name from buildings to the West


During the original compilation Myrddyn Phillips 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.  His preference was to use farm names and put Pen, Bryn or Moel in front of them or as in this instance transpose a name of a farm and add the words Twyn y to it.  This is not a practice that is now advocated 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.

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 1909 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 Lan Ucha (of the farm) Ty’n y Wern in the apportionments, with the details on the Tithe map appearing in the parish of Merthyr Cynog and in the county named as Brecon. 

Extract from the apportionments

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales and the Y Pedwarau – The 400m Hills of Wales is Lan Ucha Ty’n y Wern and this was derived from the Tithe map.

The hill is adjoined to the Mynydd Epynt group of hills, which are situated in the central part of South Wales (Region B, Sub-Region B1), and it is positioned encircled by minor roads, with the A40 road farther to its south, and has the town of Aberhonddu (Brecon) towards the south-east.

The hill appeared in the original 300m height band of Welsh P30 hills published on Geoff Crowder’s v-g.me website, under the invented and transposed name of Mynydd Aberbiran, with an accompanying note stating; Name from stream to the South-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 Pen, Bryn or Moel in front of them or as in this instance transpose the name of a stream and add the word Mynydd 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 the original publication of the Welsh P30 lists on Geoff Crowder’s v-g.me website there have been a number of 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 were digitally updated such as the Ordnance Survey Vector Map Local hosted on the Geograph website and which was entitled the Interactive Coverage Map, whilst others are current and digitally updated such as the interactive mapping on the Magic Maps and WalkLakes websites.  One of the historic maps now available online is 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 the Draft Surveyors map along with the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map and the Tithe map that has instigated the change in the listed name of this hill.

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey 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, it is this map that places the name Mynydd Aber Esgair close to its summit. 

Extract from the Ordnance Survey Draft Surveyors 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 20 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 Aberysgir Common in the apportionments, with the details on the Tithe map appearing in the parish of Aberysgir and in the county named as Brecon. 

Extract from the apportionments

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Mynydd Aberysgir and this was derived from the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map in combination with the Ordnance Survey Draft Surveyors map and the Tithe map.

When the original 300m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website, this hill was not included in the 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-evaluated and it was listed under the point (Pt. 335m) notation with 22m of drop, based on the 335m summit spot height that appears on the contemporary Ordnance Survey 1:25,000 Explorer map and the 313m bwlch spot height that appeared on the Ordnance Survey Vector Map Local hosted on the Geograph website and which was entitled the Interactive Coverage Map.

The hill is adjoined to the Mynydd Epynt group of hills, which are situated in the central part of South Wales (Region B, Sub-Region B1), and it is positioned with minor roads to its north and south, and the A483 road to its north-west, and has the town of Llanwrtyd towards the north north-east.

The hill appeared in the original 300m height band of Welsh P30 hills published on Geoff Crowder’s v-g.me website, under the invented and transposed name of Bryn Cefn Coch, with an accompanying note stating; Name from buildings to the North.

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 Pen, Bryn or Moel in front of them.  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.

However, on occasion even when research is conducted an appropriate name for the hill may not be found, and on such occasions the listing protocol is to use the point (Pt. 391.2) notation, and for this hill this is such an example.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Pt. 391.2m, and this is being used as the author has not found an appropriate name for the hill either through historic research and/or local enquiry.

The hill is adjoined to the Mynydd Epynt group of hills, which are situated in the central part of South Wales (Region B, Sub-Region B1), and it is positioned encircled by minor roads, with the A38 road farther to its north and the B4560 road farther to its east, and has the town of Talgarth towards the east north-east.

The hill appeared in the original 300m height band of Welsh P30 hills published on Geoff Crowder’s v-g.me website, under the invented name of Pen-y-gaer, with an accompanying note stating; Name from ancient hill fort at summit.

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 Pen, Bryn or Moel in front of them or as in this instance use a name that is in common usage for such ancient monuments, without confirmation of its actual use.  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.

Since the original publication of the Welsh P30 lists on Geoff Crowder’s v-g.me website there have been a number of resources made available online.  One of these is Coflein; the online database for the National Monuments Record of Wales, which constitutes the national collection about the historic environment of Wales.  Coflein documents detail associated with ancient structures, including hill forts, and for this hill and its listed name it is Coflein that use the name of Llanfilo Camp.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Llanfilo Camp and this was derived from detail supplied by Coflein.

The hill is adjoined to the Mynydd Du group of hills, which are situated in the southern part of South Wales (Region B, Sub-Region B5), and it is positioned with a minor road to its north-west, the A474 road farther to its west, the A4067 road to its south-east and the A4068 road to its north-east, and has the town of Pontadawe towards south-west. 

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

The hill appeared in the original 300m height band of Welsh P30 hills published on Geoff Crowder’s v-g.me website as a twin listed top with the prioritised name given as Tarren y Gigfran, although both this and that of Mynydd Allt-y-grug were given as twin names.

Since the original publication of the Welsh P30 lists on Geoff Crowder’s v-g.me website there have been a number of 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 were digitally updated such as the Ordnance Survey Vector Map Local that was hosted on the Geograph website and which was entitled the Interactive Coverage Map, whilst others are current and digitally updated such as the interactive mapping on the Magic Maps and WalkLakes websites, and it is the series of Ordnance Survey Six-Inch maps that form the basis of the change in the listed name of this hill.

The Ordnance Survey series of Six-Inch maps formed the base map Ordnance Survey used for many decades leading to the production of the 1:10,000 Series of maps, both have now been superseded by the digitised Master Map.  The series of Six-Inch maps are excellent for name placement and especially so compared to the contemporary Ordnance Survey 1:25,000 Explorer map, and it is the series of Six-Inch maps that prioritise the name of Mynydd Allt y Grug for this hill, with that of Tarren y Gigfran positioned against a small escarpment edge and therefore a feature name, rather than a hill name.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Mynydd Allt y Grug and this was derived from contemporary Ordnance Survey maps and priority status of the name ascertained from the Ordnance Survey series of Six-Inch maps.
