High Grove Wood (ST 423 898)
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 A48 road to its north and the M4 motorway to south, and has
the city of Casnewydd (Newport) towards the west.

The hill appeared in the original 30-99m Welsh P30
list on Geoff Crowder’s v-g.me website under the name of High Grove, which
is a name that appears close to this hill’s summit on contemporary Ordnance
Survey 1:25,000 Explorer maps.

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 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 181 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 High Grove Wood in the apportionments, with the details on the Tithe map appearing in the parish of Saint Brides Netherwent
and in the county named as Monmouth.
Extract from the apportionments |
Although the name High Grove is probably a
shortened version of the name that appears on the Tithe, it is the full Tithe
name that is now prioritised. Therefore,
the name this hill is now listed by in the 30-99m
Twmpau and Y Trechol – The Dominant
Hills of Wales is High Grove Wood, and this name was derived from the Tithe
map.
