Mapping Mountains – Significant Name Changes – Y Trichant

Llain (SO 031 628)

There has been a Significant Name Change to a hill that was surveyed for Sub-Trichant status, with the summit height, drop and status of the hill confirmed by a Trimble GeoXH 6000 survey which took place on the 2^nd February 2018 and subsequent LIDAR analysis conducted by Myrddyn Phillips.

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

Y Trichant – Welsh hills at and above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub category entitled the Sub-Trichant consisting of all Welsh hills at and above 300m and below 400m in height that have 20m or more and below 30m of drop.  The list is authored by Myrddyn Phillips and the Introduction to the list and the re-naming and publication history was published on Mapping Mountains on the 13^th May 2017.

The hill is adjoined to the Hirddywel range of hills which are situated in the northern part of Mid and West Wales (Region B, Sub-Region B1), and is positioned above the A 4081 road which is to its south-east, and has the small community of Llanllŷr to its east and the town of Llandrindod to its east south-east.

Llain (SO 031 628)

This hill was not listed in the sub list that accompanied the 300m P30 list on Geoff Crowder’s v-g.me website as it did not meet the criteria used at that time, and therefore this hill has never appeared in a published hill list, but the name given to the bounded land where the summit of the hill is situated is worth documenting as it does not appear on an Ordnance Survey map and has been derived from 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 summit of this hill is situated is given the number 655 on the Tithe map

The enclosed land where the summit of this hill is situated is given the number 655 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 Llain and described as Pasture in the apportionments accompanying the Tithe map; it appears in the county named as Radnor and in the parish of Llanyre. 

When cross referenced in the apportionments the enclosed land is named Llain

Therefore, the name this hill is now documented as is Llain and this was derived from the Tithe map.
