Two banked enclosures set close by the N bank of the stream in Cwm Crogau. The N-most is subrectangular, in the order of 10-15m N-S by 5.0-7.5m, on the S banks run down to the stream, enclosing a rectangular area. The complex is c.30m across overall.
Possibly a settlement, or folds.
The upper 0.6km of Cwm Crogau, within which these features are found, is enclosed by a bank/wall, segregating an area c.70-125m across.
