Summary :
HEN GAER;PEN GAER
Hen Gaer occupies the highest point of a rounded hill at 120m above sea level. It is a univallate fort, strongly defended by a bank and ditch up to 12m wide and 3m-4m high overall. The original entrance on the west side is a simple gap but with a large mound (PRN 2016) outside which Hogg described as resembling a Roman titulum, but he considered it likely to be modern. A watching brief in 2003-04 during cable laying, however, indicated a ditch at the base of the mound, suggesting it was part of the entrance defences. Aerial photographs show faint traces of ridge and furrow in the otherwise featureless fort interior. The interior is oval, approximately 140m by 75m, and is under improved pasture. Scrub and trees grow on the defences.
