Burgh Castle Roman Fort

Built in the late 3rd century as part of Rome's chain of 'Saxon Shore' forts, Burgh Castle stands on a low cliff above the Waveney estuary, and three of its walls survive almost to their original height, making it one of the best-preserved Roman monuments in Britain. The fourth wall collapsed into the marshes long ago, so entering by the east gate opens a wide view across Breydon Water. Look for the bastions with central holes, perhaps for catapults, one fallen outward from the south wall, and a stretch of banded flint and tile facing. After the Norman Conquest the fort became a motte-and-bailey castle. Norfolk Archaeological Trust runs the site, with free volunteer tours in summer. Reviewers single out the scale of the walls and the peaceful riverside walks. Dogs on leads are welcome, and the Angles Way long-distance path passes through the fort. Tip: use the pay car park on Butt Lane rather than the narrow village lanes.
