Dinas (SH 498 378)
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 Moel Hebog 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 A497 road to its north
and a minor road to its south, and has the town of Cricieth surrounding it.
When the original 30-99m 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. 43m) notation with an
estimated c 20m of drop, based on the 43m summit spot height that appeared on
the Ordnance Survey Vector Map Local hosted on the Geograph website and which
was entitled the Interactive Coverage Map, and an estimated c 23m bwlch height,
based on interpolation of 5m contouring between 20m – 25m.
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 576 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 Dinas in the apportionments, with the details on the Tithe map appearing in the parish of Cricieth and in the
county named as Caernarfon.
Extract from the Ordnance Survey series of Six-Inch maps |
Therefore, the name this hill is now listed by in The Welsh P15s is Dinas and this was
derived from the Tithe map. This name compliments
detail on the Ordnance Survey 1:25,000 Explorer map and the Ordnance Survey
series of Six-Inch maps.
