Hill Reclassifications post for Grug
Summit Relocations post for Grug
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.

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 that have 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.

200m Twmpau by Myrddyn Phillips |
The hill is adjoined to the Mynydd Pencarreg group of hills, which are situated in the south-western part of South Wales (Region B, Sub-Region B1), and it is positioned with a minor road to its north and south-east, and the A485 road to its east, and has the town of Llandysul towards the north north-west.
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. 266m) notation with 25m of drop, based on the 266m summit spot height positioned on a road at SN 44142 32904 that appears on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map and the 241m 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.

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 2553 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 Grug in the apportionments, with the details on the Tithe map appearing in the parish of Llanfihangel-ar-arth and in the county named as Carmarthenshire.
|
Extract from the apportionments |
Therefore, the name this hill is now listed by in the 200m Twmpau is Grug, and this was derived from the Tithe map.
The full details for the hill are:

The hill is adjoined to the Mynydd Pencarreg group of hills, which are situated in the south-western part of South Wales (Region B, Sub-Region B1), and it is positioned encircled by minor roads, with the A484 road farther to its north and the B4333 road farther to its east, and has the town of Castellnewydd Emlyn (Newcastle Emlyn) towards the north-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 Pen, Bryn or Moel in front of them or as in this instance transpose an incomplete name that appeared on the Ordnance Survey 1:25,000 Explorer map 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.

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 position the name of Allt Pen Bwlch adjacent to the summit of this hill.

Therefore, the name this hill is now listed by in the 200m Twmpau is Allt Pen Bwlch and this was derived from the Ordnance Survey series of Six-Inch maps. With the caveat that the complete name of Bwlch y Foel appears on the contemporary Ordnance Survey 1:25,000 Explorer map and the name of Banc y Foel appears on 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 Pen, Bryn or Moel in front of them or as in this instance use a prominent name that appeared close to the summit of the hill on the contemporary Ordnance Survey 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.
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. 277.7m) notation, and for this hill this is such an example with the name of the Common applicable to land that does not take in the summit of this hill.
Therefore, the name this hill is now listed by in the 200m Twmpau is Pt. 277.7m, 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 full details for the hill are:

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 is the Ordnance Survey One-Inch ‘Old Series’ map and it is this map that formed the basis for the change in the listed name of this hill.

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 this map that places the name of Pen y Castell close to the summit of the hill.
Therefore, the name this hill is now listed by in the 200m Twmpau and Y Trechol – The Dominant Hills of Wales is Pen y Castell, and this was derived from the Ordnance Survey One-Inch ‘Old Series’ map.
The full details for the hill are:
