Featured Row – Nant y Wern (Pant Serthfa) in the Brecon Beacons

View from north east (Scale 1m).

Nant y Wern also known as Pant Serthfa is a single stone row measuring at least 5.95m and possibly 54m long, including at least four or six small and medium-sized stones situated on a gentle south facing slope. The row is orientated north to south and is built across the limit of visibility to Cefn yr Ystrad.  The row is also at the limit of visibility to Pen y Fan.

    Good one. And enjoyable to read. It’s in a very “nowhere” area, as I recall. Fine views tbhough and it’s thought-provoking that Pen y Fan is visible.  Pant y Serthfa = the hollow of the steep place. The construction with a Y between two nouns always means “the … of the …” which sometimes is pretty clumsy. The fa on the end of a word sometimes means the place of / the place where, e.g, Cyfarthfa, the place of barking. Reaching a good translation often requires some interpretation, and I think it’s likely pant y serthfa means the hollow *by* the steep place. Nant y Wern seems an odd alternative. The brook of the grove / the alder / the swamp / the meadow, therefore I’d suggest The Marshy Stream. Wern / gwern is, not surprisingly, a very common place name.




  2. Thanks Miles. The hollow of the steep place is very descriptive. The row stands on a low ridge adjacent to a hollow at the foot of a cliff.
