the porches and parapets of the towers. Another characteristic is the round towers, which are confined to East Anglia, but are considerably more numerous in Norfolk than in Suffolk, the principal being those of Little Saxham and Herringfleet, both good examples of Norman. It is questionable whether there are any remains of pre-Norman architecture in the county. The Decorated is well represented, but by far the greater proportion of the churches are Perpendicular Gothic, fine examples of which are so numerous that it is hard to select examples. But the church of Blythburgh in the east and the exquisite ornate building at Lavenham in the west may be noted as typical, while the church of Long Melford, another fine example, should be mentioned on account of its remarkable lady chapel. 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. The county has a number of Martello towers along its stretch of coastline, most of which were constructed during the first decade of the 19th century to guard against a potential invasion by Napoleon Bonaparte's France.
