Vale of Glamorgan
One of the largest medieval fortresses in Britain, begun in 1268 by the Anglo-Norman marcher lord, Gilbert de Clare. Concentrically planned, the rings of stone and water defences are formidable even today. Famous for its 'leaning tower'. Impressive great hall, now used for various functions.
