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

 

Caer Wedyn (SJ 095 047) 

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 and a Trimble GeoXH 6000 survey 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 13^th May 2017.

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 has a minor road to its north-west and its south and the B4389 road to its east, and has the small town of Llanfair Caereinion towards the north north-east. 

The hill appeared in the original Welsh 300m P30 list published on Geoff Crowder’s v-g.me website, under the invented and transposed name of Bryn Ty-bwnc, with an accompanying note stating; Name from buildings to 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 and as in this instance transpose the name of an old derelict farm house and add 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.

This was one of a number of hills visited in the company of Alex Cameron during a day’s hill bagging.  When leaving the summit the sound of a quad bike appeared in an adjacent field and it quickly disappeared over the brow of the hill.  However, it thankfully reappeared and I flagged it down. 

The local farmer on the quad bike was Glyn Evans and we chatted for ten minutes or so.  It is Glyn’s field where the summit of this hill is situated and he told me that the hill doesn’t have an individual name, but the upper field where the summit is situated is known as Caer Wedyn after the name of the old landowning farm.  Glyn surmised that the older name for the hill may have been Tŷ Bwnc after the old derelict farm house, but he told us that he had no evidence to substantiate this.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Caer Wedyn, and this was derived from local enquiry.
