Castell Bryn Gwyn is a fort defended by a high bank and, unusually, occupies level ground. Excavations in 1959 and 1960 showed that the rampart and now filled-in ditch were similar in form to hillfort defences.
Excavations have shown that Castell Bryn Gwyn has a long and complex history of occupation. Neolithic flints and pottery finds from beneath the defensive bank suggest that there may have been an enclosure here around 2000BC. Subsequently and during the Iron Age the defences were rebuilt. The circular bank is very well preserved - a clay and gravel bank 10m wide and 2m high surrounds a level area 17m in diameter, now revetted by stone walls.
The site was originally surrounded by a deep ditch, which is no longer visible. Theres been some damage to the site by the building of a farmhouse.
