Cae Pant (SN 908 472) 

There has been a Significant Name Change to a hill that is listed in The Welsh P15s, with the summit height, bwlch height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips.

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

The Welsh P15s – Welsh hills with 15m minimum drop, irrespective of their height, with an accompanying sub list entitled the Welsh Sub-P15s, with the criteria for this sub category being all Welsh hills with 14m or more and below 15m of drop.  The list is authored by Myrddyn Phillips, with the Introduction to the list appearing on Mapping Mountains on the 10^th May 2019. 

The Welsh P15s by Myrddyn Phillips

The hill is adjoined to the Drygarn Fawr group of hills, which are situated in the central part of the South Wales Region (Region B, Sub-Region B1), and it is positioned with minor roads to its north-east and south, and the A483 road to its north-west, and has the town of Llanwrtyd towards the west.

When the listing that became known as The Welsh P15s was being compiled, this hill was included in the main P15 list under the point (Pt. 214m) notation with an estimated c 16m of drop, based on the 214m summit spot height that is positioned at SN 90855 47214 and which appears on the Ordnance Survey 1:25,000 Explorer map, and an estimated c 198m bwlch height based on interpolation of 10m contouring between 190m – 200m.

As the summit of this hill comprises bounded land the details for it 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 summit of this hill is situated is given the number 555 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 Cae Pant in the apportionments, with the details on the Tithe map appearing in the parish named as Llangamarch and in the county named as Brecon.

Therefore, the name this hill is now listed by in The Welsh P15s is Cae Pant and this was derived from the Tithe map.
