Castle Nimble

Castle Nimble (also called Knapp; Maes Hyfaidd; Maes Hyvaidd) was a motte and bailey defensive fortification near Old Radnor, in Radnorshire (modern-day Powys), Wales. Castle Nimble appears to have had an oval-shaped ditched motte, with a semi-rectangular bailey, and some other enclosures, including possibly a pond.
