Cae Glog Fawr (SN 750 716)
There has been a Significant Name Change to a hill that is listed in the Y Trichant – The 300m Hills of Wales, 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:
Y Trichant
– The 300m Hills of Wales – Welsh
hills at or above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub list entitled the
Sub-Trichant, with the criteria for this sub category being all Welsh hills at
or above 300m and below 400m in height with 20m or more and below 30m of
drop. The list is authored by Myrddyn Phillips with the
Introduction to the list and the renaming of it appearing on Mapping Mountains
on the 13th May 2017, and the Introduction to the Mapping Mountains
publication of the list appearing on the 1st January 2022.
Y Trichant - The 300m Hills of Wales by Myrddyn Phillips |
The hill is adjoined to the Carn yr Hyrddod group
of hills, which are situated in the northern
part of South Wales (Region B, Sub-Region B1), and it is positioned with minor roads to its north,
west and south, and the B4343 road farther to its north-west, and has the
village of Pont-rhyd-y-groes towards the north-west.
When the original 300m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website, this hill was not
included in the Hills to be surveyed
sub list, as it was considered not to meet the criteria then used for this sub
category.
After the sub list was standardised, and
interpolated heights and drop values also included the details for this hill
were re-evaluated and it was listed under the point (Pt. c 362m) notation with an
estimated c 19m of drop, based on an estimated c 362m summit height and an
estimated c 343m bwlch height, with both heights based on interpolation of 10m
contouring.

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 468 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 Glog Fawr in
the apportionments, with the details on the Tithe map appearing
in the parish of Ysbyty Ystwyth and in the county named as Cardigan.

Therefore, the name this hill is
now listed by in the Y Trichant – The 300m
Hills of Wales is Cae Glog Fawr and this was derived from the Tithe map.
