One of two ring structures, probably hut circles, is located on the poorly-drained S-facing slope to the N of Nant Fyda.

SN73801557: 26m to the SW of its neighbour, this ring structure measures 5.5m (E-W) by 5m and is defined by a stony bank 0.3m high. Again there is no obvious entrance. Loose stone is stacked against the outer SW arc.
