Roughly quadrangular (laminated) pillar stone, roughly dressed. The broad face was set towards the Roman Road, with Latin inscription facing S.W. down-slope.
Enw'r Safle: Ystradfellte, Powys
Nodiadau: Original monument was formerly located on the edge of the Roman Road, some 5 metres S.E. of its present position. It was reset in the 19th century and again in 1940, in a rectangular pavement to the W. of Sarn Helen (the Roman Road that linked Neath with Brecon). Its position suggests a road-side burial in the Roman tradition. Stone also referred to as 'Maen Madoc' (AC 1939).
