Cae Felin Wynt (SS 683 954)
There has been a Significant Name Change to a hill
that is listed in the 100m Twmpau and Y Trechol – The Dominant Hills of Wales,
with the summit height, its location, the drop and status of the hill confirmed
by LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the two listings that this name
change applies to are:
100m Twmpau - Welsh hills at or above 100m and below 200m in height with 30m
minimum drop, with an accompanying sub list entitled the 100m Sub-Twmpau with the criteria for this sub category being all
Welsh hills at or above 100m and below 200m in height with 20m or more and
below 30m of drop, with the word Twmpau
being an acronym standing for thirty
welsh metre prominences and upward.
Y Trechol – The Dominant Hills of Wales – Welsh P30 hills whose
prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose
prominence is between one third and half that of their absolute height. The list is authored by Myrddyn Phillips with
the Introduction to the start of the Mapping Mountains publication of this list
appearing on the 3rd December 2015.
The hill is adjoined to the
Fforest Fawr group of hills, which are
situated in the western part of South Wales (Region C, Sub-Region C2), and it is positioned with the B5444 and the A4217
roads to its west and the Crymlyn Bog to its east, and has the city of Abertawe
(Swansea) towards the west south-west.
The hill originally appeared in the 100m P30 list
on Geoff Crowder’s v-g.me website under the name of Cefn Hengoed, which is a
name that appears close to the summit of this hill on contemporary Ordnance
Survey maps.

During my early hill
listing I paid little regard to name placement on the map, or the meaning of
names and to what feature the name was appropriately applied to. Therefore I prioritised names for listing
purposes that I now understand are either inappropriate or where another name
is viewed as being more appropriate. And
as I have been unable to substantiate the name of Cefn Hengoed for that of the
hill I examined the Tithe map.

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.

| Extract from the Tithe map |
The enclosed land where the summit of this hill is
situated is given the number 1115 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 felin wynt in the apportionments, with the details on the Tithe map appearing in the parish of Llansamlet and in the
county named as Glamorgan.

Therefore, the name this hill is now listed by in
the 100m Twmpau and Y Trechol – The Dominant Hills of Wales
is Cae Felin Wynt, and this name was derived from the Tithe map.
