Mapping Mountains – Significant Name Changes – Y Trichant

Cromwell Hill (SJ 182 048)

There has been a Significant Name Change to a hill that is listed in the Y Trichant, with the summit height and drop of the hill being confirmed by a Trimble GeoXH 6000 survey conducted by Myrddyn Phillips which took place on the 7^th January 2018.

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

Y Trichant – Welsh hills at and above 300m and below 400m in height that have 30m minimum drop.  The list is authored by Myrddyn Phillips and the Introduction to the list and its re-naming and publication history was published on Mapping Mountains on the 13^th May 2017.

The hill is adjoined to the Carnedd Wen range of hills which are situated in the south-eastern part of North Wales (Region A, Sub-Region A4), and the hill is positioned between the A 458 road to its north and the A 483 road to its south-east, and has the town of Y Trallwng (Welshpool) to its north-east.

The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the name Pen-y-parc.  Hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of this hill the name of Pen-y-parc that appears on contemporary Ordnance Survey maps is that for the old farm situated just below this hill, and not to the hill itself.

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now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historical documents, through this form of research an appropriate name for the hill can usually be found, and in the case of this hill the name of Cromwell Hill was derived from local enquiry.

Therefore, the name this hill is now listed by in the Y Trichant is Cromwell Hill and this was derived from local enquiry.
