Pen Crwn (SN 963 736)
There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, with the hill's height and drop being confirmed by a survey with the Trimble GeoXH 6000 which took place on the 12th March
2016.
The criteria for the list that this name change applies to are:
The criteria for the list that this name change applies to are:
The hill is a part of the Pegwn Mawr range, this group of hills is situated in the north-eastern part of Mid and West Wales, and the hill is positioned to the south-west of the small community of Pant-y-dŵr and to the north of Rhaeadr Gwy (Rhayader).

The hill appeared in the 400m P30 list on Geoff
Crowder’s v-g.me website under the name of Cefn
Lletyhywel, which is a name that appeared close to the summit of the hill
on Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps of the
day.

During my early hill listing I paid little regard
to name placement on a 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 inappropriate, and Cefn Lletyhywel is
such an example as this name has been consistently applied by the Ordnance
Survey to land below and to the south of the summit of this hill, whilst a
number of different scaled Ordnance Survey maps position the name Pen Crwn as applicable to land taking in
the summit of this hill.

Therefore, the name this hill is now listed by in the Y Pedwarau is Pen Crwn
and this was derived from a number of different scaled Ordnance Survey maps
that place this name applicable to land that takes in the summit of this hill.
