Mapping Mountains - Hill Reclassifications – 100m Twmpau

Bryn y Beili (SJ 235 643) - 100m Twmpau addition

There has been a new addition to the Welsh 100m P30 list due to a recent survey with the Trimble GeoXH 6000.  The hill is situated in the centre of Yr Wyddgrug (Mold) in north-east Wales.  The name of the hill is Bryn y Beili (Bailey Hill in English), and it is almost hidden from view when approaching from the High Street as it rises behind the former Pendref Chapel and is surrounded by a high wall, trees and shrubs.  

Bryn y Beili has the remains of a Norman castle on its summit which may have been built on a much earlier burial mound.  This hill lends its name to the current usage of Yr Wyddgrug and Mold as the name of the town; yr, gŵydd, crug (high hill, the prominent mound) in Cymraeg, and mont, hault in Norman French.  

The hill was proposed by Mark Trengove as a potential new P30 and involved an exciting survey as the Trimble GeoXH 6000 was run over by a car whilst surveying in the area of the bwlch.  Our second survey attained a good data set from the tree covered summit and was backed up with a basic levelling survey from the position of a spot height just below the summit.
