Mapping Mountains – Significant Name Changes – Y Trichant – The 300m Hills of Wales

New Piece (SJ 297 141)

There has been a Significant Name Change to a hill that is listed in the Y Trichant – The 300m Hills of Wales, with the summit height, bwlch height and their locations, the drop and status of the hill derived from a Trimble GeoXH 6000 survey conducted by Myrddyn Phillips.

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

Y Trichant – The 300m Hills of Wales – Welsh hills at or above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub list entitled the Sub-Trichant, with the criteria for this sub category being all Welsh hills at or above 300m and below 400m in height with 20m or more and below 30m of drop.  The list is authored by Myrddyn Phillips with the Introduction to the list and the renaming of it appearing on Mapping Mountains on the 13^th May 2017, and the Introduction to the Mapping Mountains publication of the list appearing on the 1^st January 2022. 

Y Trichant - The 300m Hills of Wales by Myrddyn Phillips

The hill is adjoined to the Stiperstones group of hills, which are situated in the eastern part of South Wales (Region B, Sub-Region B2), and it is positioned with the B4393 road to its north-east, the A483 road to its west and the A458 road to its south, and has the town of Y Trallwng (Welshpool) towards the south-west.

The hill appeared in the original 300m height band of Welsh P30 hills published on Geoff Crowder’s v-g.me website, under the transposed and invented name of Breidden Forest Top, with an accompanying note stating; Name from forest at summit.

Name from forest at summit

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, with little consideration for the meaning of the name and where it was appropriately applied to.  My preference was to use farm names and put Pen, Bryn or Moel in front of them or as in this instance transpose the name of a forest and add the word Top to it.  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. 

Extract from the Tithe map

The enclosed land where the summit of this hill is situated is given the number 749 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 New Piece in the apportionments, with the details on the Tithe map appearing in the parish of Alberbury and in the county named as Montgomery. 

Extract from the apportionments

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is New Piece and this was derived from the Tithe map.

Cefn y Castell (SJ 305 133)

Freshly enthused with the prospect of determining the absolute height of many a hill can give added impetus to revisit areas that have not been visited for many a year.  It was with this added enthusiasm that I set out for some of my local hills; the Breiddin.  I’d done a circuit of all the P30’s and Subs in this compact hill group a few years ago and had always wondered if I would repeat it.  With the forecast of winter sunshine and with confidence in using the Trimble I decided that five P30’s and two Subs, including one Marilyn and two marginal HuMPs was the order of the day.

The route took me up through patches of woodland where on my last visit I’d disturbed two deer, a rare sight on hills in mid Wales, to the grassy summit of Pritchard’s Hill (SJ 316 147).  Footpaths on the map indicated that I had to venture in to the back garden of a house before walking down a track to gain the lower slopes of Kempster’s Hill.  I was soon confronted with ‘Oh you, what are you doing there!’  This was the owner of the house who had spotted me from the end of the track, I sheepishly approached and apologised for any disturbance and then spent the next ten minutes in conversation about the local names of the hills.

By now the sun was up casting lengthy shadows on the ground as patches of mist in the valley below were edging their way around bends in the River Severn.  Gaining the summit of Kempster’s Hill (SJ 318 143) the open land of Shropshire was on view with sunlight enhancing the ridge of the Stiperstones.  I surveyed the high point and look forward to the result as no absolute height appears on the map for this hill.

My next objective was Cefn y Castell (SJ 305 133), otherwise known as Middletown Hill.  Passing over Bulthy Hill (SJ 312 136) I decided to give it a quick survey.  Five minutes later I packed the Trimble in its protective case and carried on up the ridge to the summit of Cefn y Castell.

Gathering data on the summit of Cefn y Castell (SJ 305 133)

The time was now approaching 10.30am and a bank of cloud had appeared skimming the upper reaches of Cefn Digoll (Long Mountain).  This soon expanded to envelop the top of Moel y Golfa and the Breiddin with wisps of cloud gently rolling down the valley either side of where I stood.

I chatted with a man walking his two dogs on the way down to a 307m sub-hill and gathered data at its bwlch and summit, before assessing the bwlch of Cefn y Castell which has a 271m spot height on the narrow road on the Ordnance Survey enlarged mapping on the Geograph website.  This area has a parking ground for cars and I decided that the safest place for the Trimble was adjacent to this area on a grass verge.  It also seemed to be the point of the critical bwlch that could be deemed as ‘natural’.

The next hill was the highest and the only Marilyn of the day; Moel y Golfa (SJ 290 125).  The last time I had visited was with Bob Kerr who was staying over during his visits to film and be interviewed on his attempt of the Seven Summits (the continental high points).  On that particular day we sought shelter just below the summit amongst trees as there was a brisk wind that would destroy the audio on the small digital camera I conduct the interviews with.  Today the summit was peaceful with the bank of cloud greying the valley and the sun breaking through to highlight the colours on the higher land.  Twas a fine time to be out on the hill.

As each summit and bwlch was visited I collected a minimum of five minutes of data and continued this process as I attempted to decipher where the critical bwlch position was for the Breiddin.  Was it beside a tree in a field or on a gravel track or in another field full of sheep with rummaging pigs alerting local farmers of my presence?  I opted for data collection beside the tree and on the gravel track and quickly headed in to the Breiddin Forest where a series of wooded green tracks and the customary forest track took me over the summit of New Piece (SJ 295 136) toward its bwlch and then the summit of New Piece (SJ 297 141) a sub P30 hill whose name was later found from Tithe maps.

Next stop was the Breiddin and its large monument named Rodney’s Pillar.  I had a good look around the base of the monument and assessed the height of the natural rock on its four sides.  This is where a level and staff comes in to its own as judging by eyesight alone is not ideal.  The Trimble was set up and activated and gathered over 13 minutes of data as I pottered around with the camera and visited a nearby panoramic viewfinder.

The downward route through the forest was on a good green track all the way down the ridge toward the Admiral Rodney pub to the awaiting car.  I’d been out over seven hours and collected data at sixteen points.  A Marilyn, two marginal HuMPs, a further two P30’s and two subs and all except for one critical bwlch (the one for Moel y Golfa) had been surveyed.  It proved a great day on the hill.

Postscript 

Since visiting these hills full LIDAR coverage is now available.  The LIDAR (Light Detection & Ranging) technique produced highly accurate height and positional data that is now freely available for England and Wales.  Consequently the numerical details for these hills have been analysed using this technique, resulting in the LIDAR height and position being prioritised for some of these hills.
