Site Description
Caer Penrhos is a triangular or boomerang shaped hillfort, some 258m north-south by 142m, with an entrance at the north-eastern end. It occupies a promontory position with its strongest defences facing east. A medieval castle ringwork has been superimposed on eastern side of hillfort. This is some 67m by 48m and is probably the castle recorded as having been built by Cadwaladr apGruffyd - the 'War Dragon of Llanrhystud' - in 1148.
RCAHMW aerial reconnaissance has revealed a double-ditch system cutting across neck of promontory outside the north-eastern entrance, comprising two ditches about 40m apart, following outline of earthwork defences. These lend weight to argument for a prehistoric date for the site, despite it being rejected by Hogg in the 1994 Cardiganshire County History.
