Mapping Mountains – Significant Name Changes – 300m Twmpau


Tyfaenor Park (SO 070 715)

This is the fiftieth post under the heading of Significant Name Changes, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 18th February 2016.

The hill is part of the group of hills associated with Pegwn Mawr, this range of hills is situated in the north-eastern part of Mid and West Wales.  The hill is positioned to the east north-east of the small community of Abaty Cwm-hir (Abbeycwmhir) and to the north north-west of the meeting of the Bachell Brook and the Clywedog Brook.

Tyfaenor Park (SO 070 715)

The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the name Tyfaen.  This name was derived from that of Tyfaenor Park which appeared on the maps of the day as well as on current Ordnance Survey maps.  It is not known why the first word of the name which is wholly appropriate for the hill was shortened.  The listing this hill is now a part of is named Twmpau (thirty welsh metre prominences and upward) and its height, drop and status was confirmed by the survey with the Trimble.

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put Pen, Bryn or Moel in front of them or as in this instance, shorten the name that in itself is appropriate to use.  This is not a practice that I now advocate as with a little research either conducted locally or historically an appropriate name for the hill can usually be found.  

Since publication of these P30 lists on Geoff Crowder’s v-g.me website there have been a number of Ordnance Survey maps made available online, some of these are historical such as the series of Six-Inch maps on the National Library of Scotland website, whilst others are current and digitally updated such as the enlarged map on the Geograph website.  Two of the historical maps now available are the Ordnance Survey Draft Surveyors map which formed the basis for the Ordnance Survey One-Inch ‘Old Series’ map, and these maps coupled with that of the Tithe map formed the basis for the confirmation of this hill’s name.

The name this hill is now listed by is Tyfaenor Park and the land that this name is applicable to was confirmed via 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.

Accessing information on the Tithe map is simplified by the use of a split screen enabling the summit to be pinpointed on the map on the right and for the same point to appear on the Tithe map on the left

The enclosed land where the summit of Tyfaenor Park is situated is given the number 466 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 appears in the county named as Radnor and in the parish of Llanbister. 

The name where the summit of the hill is situated is named in the apportionments

There are many maps that are now available online and these give the opportunity to compare the composition of a hill’s name and in the instance of Tyfaenor Park this can be followed from the Draft Surveyors map, through the Tithe map, to the Ordnance Survey One-Inch ‘Old Series’, the Six-Inch map and to the current Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps.  There are of course many other maps also available for this form of comparison, but the study of the ones mentioned above can give us inkling to how this hill’s name was represented through the ages and this is depicted below:

Ordnance Survey Draft Surveyors map:  Divanner Park

Tithe Map:  Devanner Park

Ordnance Survey One-Inch ‘Old Series’ map:  Devanner Park

Ordnance Survey Six-Inch map:  Ty-faenor Park

Ordnance Survey 1:50,000 and 1:25,000 map:  Tyfaenor Park 


Therefore the name this hill is now listed by in the Twmpau is Tyfaenor Park, and this was derived from a number of sources, including the Tithe map for what land the name applied to, and the current Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps for name confirmation.  


The full details for the hill are:

Previously Listed Name:  Tyfaen

OS 1:50,000 map:  136, 147
