Mapping Mountains – Significant Name Changes – Y Pellennig, Yr Uchafion and 800m Twmpau

Craig Berwyn (SJ 071 323)

This is the ninth post under the heading of Significant Name Changes, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 21st June 2014.

The hill is situated in Y Berwyn, which is an extensive group of hills positioned in the south-east part of north Wales, and is relatively remote for a Welsh hill with the nearest towns being Llandrillo to the north-west and Llanarmon Dyffryn Ceiriog to the east.

The hill first made an appearance in a hill list as Cader Berwyn, S. Top in a 1929 update to the Twenty-Fives which was compiled by John Rooke Corbett and published by the Rucksack Club Journal.  Since this time the hill has been listed a number of times and usually by names associated with that of Cadair Berwyn, which strictly speaking is the hill to its north at SJ 072 327, and which has a triangulation pillar on it and a map height of 827m.

Unfortunately all previous hill list authors have used the map name that appears nearest to this hill’s summit, although doing this is convenient it has conjured up all manner of inappropriate combination of names centred around that of its adjacent hill, including Cadair Berwyn New Top, Cadair Berwyn South Top as well as the use of the adjacent hill’s name; Cadair Berwyn.

The hill was only confirmed by the Ordnance Survey as the highest in Y Berwyn when contacted by Bernard Wright who had recognised that the summit of the hill was higher than its adjacent northerly peak; Cadair Berwyn, and also of its adjacent southerly peak; Moel Sych, Bernard suggested the name of Craig Uchaf for this hill as it seemingly had no name for it on the map of the day.  This is the name previously given the hill in unpublished format before extensive place-name research for this area took place.

As a result of this research the hill has subsequently been listed under the name of Craig Berwyn in Y Pellennig – The Remotest Hills of Wales (Europeaklist, Haroldstreet, and Mapping Mountains 2015) which is the name that some local farmers and shepherds know it by, and which already appears on current Ordnance Survey maps.

The full details for the hill are:
