CAER BLAEN- Y-CWM MARGAM
Primary Reference Number (PRN) : 00759w Trust : Glamorgan Gwent Community : Margam Unitary authority : Neath Port Talbot NGR : SS83338807 Site Type (preferred type first) : Iron Age Hillfort Status : Scheduled Monument
Summary : Caer Blaen-y-cwm stands at 300 m above OD. The enclosure is quadrangular, covering 0.1ha and is defended by two banks (4 to 6m wide, 0.7m high), separated by a ditch (1.5m deep from the edge of the banks). The entrance is on the S and is 4.5m wide.
Description : Caer Blaen-y-cwm stands at 300 m above OD on a broad mountain spur falling gently to the S, about 4 km SW of Maesteg (RCAHM 1976). The enclosure is quadrangular, with west side measuring 25m, the north 31m, the east 39m and the south 44m, overall covering 0.1ha. The enclosure is defended by two banks (4 to 6m wide, 0.7m high), separated by a ditch (1.5m deep from the edge of the banks). The overall width is 11 to 15m. A hollow crosses the enclosure from the N to the S. On the N it has breached the defences, but on the S it appears to have been adapted to the original entrance, a 4.5m wide gap.
Caer Blaen-y-Cwm stands at 300m OD on a broad mountain spur falling gently to the S about 4km SW of Maesteg. The enclosure is quadrangular, the W and N sides straight, the E and S bowed outwards slightly. The area is 0.1ha. It is defended by a ditch between two banks. The overall width is 11 to 15m. A hollow trail cuts right through the fort from N to S. On the N it has breached the defences, but on the S it appears to have utilised the original entrance, which survives as a gap 4.5m wide through both banks. The interpretation of the site published by Sir Cyril and Lady Fox (Antiquity VIII 1934, 400) suggests that the fort lies at the centre of a much larger square enclosure about 210m across. However reconsideration of the various earthworks suggests that they are not contemporary with the fort, or at any rate do not constitute an enclosure. (Wiggins and Evans 2005)
