Mapping Mountains – Hill Reclassifications – 100m Twmpau

Castell Dinbych (SJ 051 657) - 100m Sub-Twmpau reclassified to 100m Twmpau 

There has been a reclassification to the Twmpau list with a 100m Sub-Twmpau being reclassified to a 100 Twmpau due to a survey with the Trimble GeoXH 6000.  The hill is situated in the centre of Dinbych (Denbigh) in north-east Wales, and its name is Castell Dinbych (Denbigh Castle in English).  

The present construct is the remains of one of Edward 1’s fortifications after he visited his neighbours and asked them not to be so rebellious.  It is situated in an impressive position overlooking the town to the west and the Vale of Clwyd to the east.  In its time the castle must have been an imposing construction, one no doubt meant to subjugate.  

The critical bwlch of the hill may be placed in someone’s living room beside a road named Bryn Stanley; I asked permission to place the Trimble on a fence post adjacent to a front garden as satellite reception may have been awkward inside the bungalow.
