Powys, Mid-Wales (SO 123 922)

An impressive motte laying to the east of Newtown (possibly now in the golf course?). The inner bailey is 18m x 38m, and has strong defences in the form of the River Severn to the east and north.  The motte reaches a height of 9m, with a summit of 11m across.  Other defences included a ditch. The outer bailey was 30m x 45m, with a 2m rampart protecting the outside flank of the motte. Probably built by Roger de Montgomery in the 1080s, to protect the important route alongside the Severn (other castles including Hen Domen, Montgomery, and Dolforwyn, in addition to Roman forts at Caersws and Forden Gaer).
