NAR SH77SE14

A mound traditionally identified as the site of a medieval castle. It is situated close to the modern bridge of Pont Tal-y-cafn, which replaced a more ancient ferry.
This is an oval or near rectangular steep sided mound, about 30m across north-south and 4.0m high. It has a level summit some 15m across. The mound has been disturbed on the east, where a building is shown on the 1st edition OS County series (Caernarvon. IX.9 1888). There is apparently no trace of a ditch.
With the exception of the mighty Conwy, this is the only castle in Arllechwedd Isaf commote. It is possible that this was the site of a llys, a princely court, before the rise of Conwy.
