Mapping Mountains – Significant Name Changes – Y Trichant


Bryn-glas Bank (SO 103 559)

There has been a Significant Name Change to a hill that was surveyed for potential Y Trichant status, with the summit height and lowest summit of the hill being confirmed by a Trimble GeoXH 6000 survey which took place on the 6th September 2017.

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

Y Trichant These are the Welsh hills at and above 300m and below 400m in height that have 30m minimum drop,  with the introduction to the re-naming and publication history of this list appearing on Mapping Mountains on the 13th May 2017.

The hill is adjoined to the Fforest Glud range, this group of hills is situated in the south-eastern part of Mid and West Wales (Region B, Sub-Region B1), and the hill is positioned between the two small communities of Frank’s Bridge to the east and Llansanffraid-yn-Elfael (Llansantffraed-in-Elwel) to the south south-west.

The summit is adjoined to a higher summit, both of which can be construed as being a part of the same hill, with a 356m and 357m map height respectively.  The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the name of Hirllwyn Bank.  Although the lower summit does not have sufficient prominence to qualify even for Sub-Twmpau status it is worthwhile documenting the name of it.

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 and used many names that seemingly applied to a hill and whose placement was nearest the summit of the hill on Ordnance Survey maps of the day.  Therefore I prioritised names for listing purposes that I now understand are inappropriate.  This hill is such an example, and as both summits consist of bounded land the details for each were examined on the Tithe map.

The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act.  This act allowed tithes to be paid in cash rather than goods.  The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.  This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.

The enclosed land where the lower summit of this hill is situated is given the number 252 on the Tithe map

The enclosed land where the lower summit of this hill is situated is given the number 252 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land.  The land where the summit of this hill is situated is named as Bank on the Tithe map and described as Pasture, importantly the land is that adjoined to the farm of Bryn-glas, in affect it is the Bank of Bryn-glas, or simply put; Bryn-glas Bank; the details on the Tithe map appear in the county named as Radnor and in the parish of Llansanffraid-yn-Elfael.

When cross referenced in the apportionments the enclosed land is named Bank and is adjoined to Brynglas

When visiting this hill and its near neighbours I made several place-name enquiries, one of which was with Philip Dyke who was out on his quad bike on a field directly below this hill’s summit.  Philip is aged 62 and farms from Gwernfach having lived there for 57 years, with his family having lived in this area for hundreds of years, and he confirmed that the land where the lower summit is situated is known as Bryn-glas Bank, and the land of the higher summit is known as Gwernhwsmon Bank which also confirms information from the Tithe map.  

Therefore, if this summit were higher than Gwernhwsmon Bank (357.3m [converted to OSGM15] at SO 10538 55967) it would be listed as Bryn-glas Bank in the Y Trichant, and this name was derived from the Tithe map and also confirmed locally.

Previously Listed Name:  (higher summit previously listed as) Hirllwyn Bank
