Cae Rosser (SO 388 005)
There has been a Significant Name Change to a hill
that is listed in the 30-99m Twmpau and
Y Trechol – The Dominant Hills of Wales,
with the summit height, bwlch height and their locations, the drop, dominance
and status of the hill confirmed by LIDAR analysis conducted by Myrddyn
Phillips.

The criteria for the two listings that this name
change applies to are:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height with 30m minimum
drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the
criteria for this sub category being all Welsh hills at or above 30m and below
100m in height with 20m or more and below 30m of drop, with the word Twmpau
being an acronym standing for thirty
welsh metre prominences and upward.
Y Trechol – The Dominant
Hills of Wales
– Welsh P30 hills whose prominence equal or exceed half that of their absolute
height. With the criteria for Lesser
Dominant status being those additional Welsh P30 hills whose prominence is
between one third and half that of their absolute height. The list is authored by Myrddyn Phillips with
the Introduction to the start of the Mapping Mountains publication of this list appearing on the 3rd December 2015, and which is now available in its entirety on Mapping Mountains in Google Doc format.
The hill is adjoined to the Gwent Is Coed group of hills which are situated in the
south-eastern part of South Wales (Region C, Sub-Region C3), and it is positioned
with the A472 road to its north and the A449 road to its east and the Afon Wysg
(River Usk) to the west, and has the town of Brynbuga (Usk) towards the north north-west.
The hill originally appeared in the 30-99m P30 list on Geoff Crowder’s v-g.me website under the transposed name of Red Hill, which is a name adjoined to a minor road
on the contemporary Ordnance Survey 1:25,000 Explorer map and not necessarily
to the hill itself.

During my early hill
listing I paid little regard to name placement on the map, or the meaning of
names and to what feature the name was appropriately applied to. Therefore I prioritised names for listing
purposes that I now understand are either inappropriate or where another name
is viewed as being more appropriate.

As this hill comprises bounded land the Tithe map
was consulted. 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 317 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 Rosser in the apportionments, with the details on the Tithe map appearing in the parish of Llangeview [sic] and in the county named as
Monmouth.

Therefore, the name this hill
is now listed by in the 30-99m Twmpau
and Y Trechol – The Dominant Hills of
Wales is Cae Rosser, and this was derived from the Tithe map.
