Cae Nesaf Glanrafon (SH 317 387)
There has been a Significant Name Change to a hill
that is now listed in the 100m Twmpau, with
the summit height, drop and status of the hill being confirmed by LIDAR
analysis conducted by Myrddyn Phillips.
The criteria for the list that this name change
applies to are:
100m Twmpau – All Welsh hills at and above 100m and below 200m
in height that have 30m minimum drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.
With an accompanying sub category entitled the 100m Sub-Twmpau consisting of all Welsh hills at and above 100m and
below 200m in height that have 20m or more and below 30m of drop.
The hill is adjoined to the Pen Llŷn range of hills which are
situated in the north-western part of North Wales (Region A, Sub-Region A1),
and is positioned overlooking the B 4354 road which is to its immediate north
and the A 497 road which is to its south-west and has the small community of
Nefyn to its north-west.
The hill did not appear in the 100m P30 list on
Geoff Crowder’s v-g.me website as it did not meet the criteria set for the
accompanying sub list which was entitled Hills
to be surveyed, however when this sub list was standardised and interpolated
drop values later added the hill was only listed with an estimated c 18m of
drop, and it was LIDAR analysis that classified it to the 100m Sub-Twmpau category.
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.

The enclosed land where the summit of this hill is
situated is given the number 171a and the adjacent field to the south the
number of 171 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 and that of the southerly field is named as Cae nesa glanrhafon, with
the details
on the Tithe map appearing in the county named
as Carnarvon [sic] and in the parish
of Bodean.

Therefore, the name this hill is now listed by in
the 100m Twmpau is Cae Nesaf
Glanrafon, and this name was derived from the Tithe map.
