Summary :
Castell Bach is a bivallate coastal promontory fort with a concentric annexe lying just 20m above the sea, naturally defended to the north and west by sea cliffs. Two sets of curving bank and ditch c. 90m long defend the easily approachable east/northeast side and enclose an area of about 0.3ha. There is no obvious entrance. A second slighter defensive bank with evidence of a stone revetment lies approximately 100m to the east, and extends from a natural scarp to the sea cliffs. The interior of Castell Bach is overlooked from the scarp. A survey by K Ray indicated that the inner enclosure originally had just one bank and ditch, and that the second was added at the same time as the outer defence. The site is under pasture. K Murphy 14 December 2005 - from Cadw and Ordnance Survey descriptions.
