Mapping Mountains – Significant Name Changes – Y Pedwarau


Foel Eryr (SN 065 320)

There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 12th September 2015.

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

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, and the introduction to the Mapping Mountains publication of this list appeared on the 30th January 2017.

The hill is a part of the Mynydd Preseli range, which is a group of hills situated in the south-western part of mid and west Wales.  The hill is positioned between the small communities of Brynberian to the north-east, Pontfaen to the west north-west and Maenclochog to the south south-east.

Foel Eryr (SN 065 320)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name of Cerrig Lladron, which is a name that appeared close to the summit of the hill on Ordnance Survey maps of the day.

During my early hill listing I paid little regard to name placement on a map, or the meaning of names and to what feature the name was appropriately applied to.  Therefore I prioritised names for listing purposes that I now understand are inappropriate, and Cerrig Lladron is such an example as this name has been consistently applied by the Ordnance Survey to a patch of stony ground to the north-east of this hill’s summit, whilst the same maps are consistent in applying the name Foel Eryr to the hill and not just to a feature on the hill.

The use of this name is substantiated by the name used on the panoramic viewfinder at the summit of the hill where Foel Eryr is inscribed as the name of the hill.  Therefore the name this hill is now listed by in Y Pedwarau is Foel Eryr and this name appears on contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps.
