Penarth (ST 188 720)
There has been a Significant Name Change to a hill
that is listed in the 30-99m Twmpau and
Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height
and their locations, the drop, dominance 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:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height with 30m minimum
drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all
Welsh hills at or above 30m and below 100m 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, with
the Introduction to the Mapping Mountains publication of this list appearing on
the 3rd December 2015, and is now available in its entirety on Mapping Mountains in Google Doc format.
The hill is adjoined to the Bro Morgannwg group of
hills, which are situated in the southern part of South Wales (Region C,
Sub-Region C2), and it is positioned with the A4160 road to its south-west and
the Bristol Channel to its east, and with the summit of the hill being a part
of the town that takes its name from the hill; Penarth, which is situated to
the south of the city of Caerdydd (Cardiff).
The hill appeared in the original 30-99m Welsh P30
list on Geoff Crowder’s v-g.me website under a partly transposed and invented
name of Penarth Head Hill, with an accompanying
note stating; Name from headland to the East.

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 transpose the name of a headland and add the word Hill to it. This is not a practice that I now advocate as
with time and inclination place-name data can be improved either by asking
local people or by examining historic documents, through this form of research
an appropriate name for the hill can usually be found.
Extract from the Ordnance Survey 1:25,000 Explorer map |
The land this hill incorporates takes in the
headland that encloses the hill to its east; this is named Penarth Head on
contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer
maps. The summit of this hill is now a
part of an urban development and town, which is named Penarth; with the town
taking its name from the hill. The
translation of Penarth can mean head of
the promontory; therefore Penarth Head is tautological, albeit with the
repetition in a different language.
Therefore, the name this hill is now listed by in
the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Penarth, and this was derived from
contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps and
deduction of the names meaning.
