Mapping Mountains – Significant Name Changes – The Welsh P15s


Newry (SO 048 504) 

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 10th May 2019. 

The Welsh P15s by Myrddyn Phillips

The hill is adjoined to the Mynydd Epynt group of hills, which are situated in the central part of South Wales (Region B, Sub-Region B1), and it is positioned with the A470 road to its north and east, a minor road to its west and the B4520 road farther to its west, and has the town of Llanfair-ym-Muallt (Builth Wells) towards the north-west.

When the listing that became known as The Welsh P15s was being compiled, this hill was listed under the point (Pt. 193m) notation with an estimated c 15m of drop, based on the 193m summit spot height that appears on the Ordnance Survey 1:25,000 Explorer map and an estimated c 178m bwlch height, based on interpolation of 10m contouring between 170m – 180m.

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 231 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 a part of Newry farm in the apportionments, with the details on the Tithe map appearing in the parish named as Llanddewi’r-cwm and in the county named as Brecon.

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