Mapping Mountains – Significant Name Changes – 200m Twmpau


Castell (SH 655 061)

There has been a Significant Name Change to a hill that is listed in the 200m Twmpau, with the summit height and drop of the hill being confirmed by a Trimble GeoXH 6000 survey which took place on the 14th May 2018.

The criteria for the list that this name change applies to are:

200m Twmpau – Welsh hills at or above 200m and below 300m in height that have 30m minimum drop.  With the word Twmpau being an acronym standing for thirty welsh metre prominences and upward. 

The hill is adjoined to the Tarennydd range of hills which are situated in the south-western part of North Wales (Region A, Sub-Region A3), and it is positioned between two river valleys with the Afon Dysynni to its north-west and the Afon Fathew to its south, and has the small community of Dolgoch towards the south and Abergynolwyn towards the east north-east. 

Castell (SH 655 061)

The hill appeared in the 200m P30 list on Geoff Crowder’s v-g.me website under the invented name of Bryn Rhiwerfa with an accompanying note stating; Name from buildings to the East.

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put Pen, Bryn or Moel in front of them.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

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 2133 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 Castell on the Tithe map, the details of which appear in the county named as Merioneth and in the parish of Towyn.

When visiting this and adjoining hills I met a number of local farmers, including Joanne Redman on the summit of Coed Uchaf (SH 649 055), Joanne was on her quad bike taking photos of her father’s farm, Nant-y-mynach (SH 644 048), we talked about this and other hills and Joanne suggested that I should contact her father; Tomos Lewis, whose telephone number she kindly gave me.

The following day I contacted Tomos and two days later then visited him, Tomos is aged 60 and a Welsh speaker, and has lived at Nant-y-mynach for 54 years, having moved there from the council houses in Abertrinant when aged six.  During our conversations Tomos proved very knowledgeable and gave me many hill names that do not appear on any Ordnance Survey map, and one of them was the name for this hill which he said was known as Castell, this was during our telephone conversation, when we met he referred to this hill by its plural; Cestyll.

Therefore, the name this hill is now listed by in the 200m Twmpau is Castell and this was derived from the Tithe map and substantiated by local enquiry.
