Mapping Mountains – Significant Name Changes – Y Trichant

Llanbradach Tip (ST 137 916)

There has been a Significant Name Change to a hill that is listed in the Y Trichant, with the summit height and its location confirmed by LIDAR analysis conducted by Myrddyn Phillips, and its bwlch height and location derived from the Ordnance Survey Vector Map Local hosted on the Geograph website and which is entitled the Interactive Coverage Map.

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

Y Trichant – 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 Cymoedd Gwent group of hills, which are situated in the eastern part of South Wales (Region C, Sub-Region C2), and it is positioned with the B4263 road to its south-west and the A469 road and the Afon Rhymni (Rhymney River) to its east, and has the small community of Llanbradach towards its south-east.

The hill appeared in the original Welsh 300m P30 list on Geoff Crowder’s v-g.me website under the partly invented and transposed name of Mynydd Llanbradach, with an accompanying note stating; Name from buildings to the South-East.

Name 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 Pen, Bryn or Moel in front of them or as in this instance transpose the name of a small community 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.

Since publication of these P30 lists on Geoff Crowder’s v-g.me website research in to appropriate names of hills has been made easier by the availability of the Internet, and a search online names the deposited mine spoil from which this hill and adjacent smaller hills are made of as a part of the Llanbradach Tip, and this is the name this hill is now listed by.

Therefore, the name this hill is now listed by in the Y Trichant is Llanbradach Tip, and this was derived from online sources.
