Bayham Old Abbey: The impressive ruins of an abbey of Premonstratensian 'white canons', on the Kent-Sussex border. They include much of the 13th to 15th-century church, the chapter house, and a picturesque 14th-century gatehouse. Now set in a landscape designed by Humphry Repton, the famous landscape gardener, who also planned the grounds of Kenwood House in London. Rooms in the 'Georgian Gothick' dower house are also open to visitors.
