Slide of RCAHMW colour oblique aerial photograph of Caer Cadwgan, taken by T.G. Driver, 19/12/1999.

Caer Cadwgan is an oval enclosure, approximately 96m from north-east to south-west by 55m. It is defined by scree-like tumbled walls crowning a distinct hill above the Ffrwd Cynon valley. It also shows traces of a dividing wall, enclosing the higher, south-eastern part of the main enclosure. A less substantially defined outer circuit encloses an area about 60m across on the eastern and southern sides, with an entrance on the west, to the north of which is a possible oval banked and terraced enclosure, about 36m across, abutting the main circuit.

Excavations between 1984 and 1989 recorded details of a north-east facing entrance, subsequently blocked, and examined an area of the interior, with the remains of two circular structures, one of which was multiphase, its sequence interupted by a four-post structure. Occupation may have extended into the Roman period, with subsequent re-use (or continuing use).
