Cerrig Engan (SH 405 734)
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 coast to its west, minor roads to its north-east, west and
south, the A55 and A5 roads farther to its north and the B4422 road farther to
its south-east, and has the town of Llangefni towards the east north-east.
When the listing that became known as The Welsh P15s was being compiled, this
hill was not included in either the main P15 list or the accompanying P14 sub
list, but it was documented under the point (Pt c 70m) notation with an
estimated c 13m of drop, based on an estimated c 70m summit height and an
estimated c 57m bwlch height, with both heights based on interpolation of 5m
contouring that appear on the Ordnance Survey 1:25,000 Explorer 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.

The enclosed land where the summit of this hill is
situated is given the number 84 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 Cerrig Engan in the apportionments, with the details on the Tithe map appearing in the parish of Aberffraw and in the
county named as Anglesey.

Therefore, the name this hill is listed by in The Welsh P15s is Cerrig Engan and this
derived from the Tithe map.
