The site at Ceunant Egryn appears to be a later Prehistoric settlement enclosure. It is roughly D-shaped, some 42m east-west by 26m deep, and occupies a declining spur set high above the steep valley of the Ceunant stream. It is defined by a curving rubble stone wall on the north. This is some 2.5m wide and appears to be defined by rows of earthfast orthostatic stones. In the sloping interior is a curving building platform about 10m by 8.0m. Excavations in 1919 recovered an iron terret or harness ring and traces of a hearth. The site can be identified as a concentric settlement enclosure in which an imposing thatched roundhouse was set within a concentric walled enclosure.
