1. Brawdy Castle is an enclosure set above the confluence of two streams, some 430m east-southeast of St David's Church, Brawdy (NPRN 419487). It is defined on the south and east by steep natural scarps, whilst about the north and west is a quadrant of three banks with intermediate ditches. The roughly triangular interior has a maximum depth of 48m, the defences occupying a band about 50m across.
An excavation, 1985-91, produced evidence for Iron Age, Romano-British, and later occupation.
