Cae Mawr (SH 468 648)
There has been a Significant Name Change to a hill
that is listed in The Welsh P15s,
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:
The Welsh
P15s – Welsh hills with 15m
minimum drop, irrespective of their height, with an accompanying sub list entitled the Welsh Sub-P15s,
with the criteria for this sub category being all Welsh hills with 14m or more
and below 15m of drop. The list is authored by Myrddyn Phillips, with the
Introduction to the list appearing on Mapping Mountains on the 10th
May 2019.

The Welsh P15s by Myrddyn Phillips |
The hill is adjoined to the
Ynys Môn group of
hills, which are situated in the
north-western part of North Wales (Region A, Sub-Region A1), and it is positioned
with the Menai Strait to its immediate south-east, the B4419 road to its north,
the A4080 road to its north-west and a minor road to its west, and has the
village of Dwyran towards the west north-west.

When the listing that became known as The Welsh P15s was being compiled, this
hill was listed under the point (Pt. 23m) notation with an estimated c 19m of
drop, based on the 23m summit spot height that appears on the Ordnance Survey
1:25,000 Explorer map and an estimated c 4m bwlch height, based on
interpolation of 5m contouring between 0 – 5m.

Extract from 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 apportionments |
The enclosed land where the summit of this hill is
situated is given the number 200 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 Mawr in the apportionments, with the details on the Tithe map appearing in the parish of Llangeinwen and in the
county named as Anglesey.
Therefore, the name this hill is now listed by in The Welsh P15s is Cae Mawr and this was
derived from the Tithe map.
