Remains of old castles include part of the walls of Bungay, the ancient stronghold of the Bigods; the picturesque ruins of Mettingham, built by John de Norwich in the reign of Edward III; Wingfield, surrounded by a deep moat, with the turret walls and the drawbridge still existing; the splendid ruin of Framlingham, with high and massive walls, founded in the 6th century, but restored in the 12th; the outlines of the extensive fortress of Clare Castle, anciently the baronial residence of the earls of Clare; and the fine Norman keep of Orford Castle, on an eminence overlooking the sea. Among the many fine residences within the county there are several interesting examples of domestic architecture of the reigns of Henry VIII and Elizabeth. Hengrave Hall (c. 1530), north-west from Bury St Edmunds, is a noteworthy example an exceedingly picturesque building of brick and stone, enclosing a courtyard. Another is Helmingham Hall, a Tudor mansion of brick, surrounded by a moat crossed by a drawbridge. West Stow Manor is also Tudor; its gatehouse is fine, but the mansion has been adapted into a farmhouse.
