Burgh Castle (Roman *Gariannonum*) is one of the best-preserved Saxon Shore forts, built in the later 3rd century AD (likely c. 260–280) on a low promontory overlooking the former estuary of the Yare and Waveney, which then formed a broad tidal inlet. The fort encloses roughly 6 acres within massive flint-and-tile walls still standing up to 4.5 m high on three sides, with characteristic external bastions added during or shortly after the initial construction. A *vicus* developed outside the walls, and after the Roman period the site was reused for an early monastic foundation (probably Fursa's *Cnobheresburg*, c. 630s) and later a Norman motte-and-bailey castle inserted into the southwest corner.

As a key node in the Saxon Shore defensive system listed in the *Notitia Dignitatum* (where *Gariannonum* is garrisoned by the *equites stablesiani*), it controlled access to the rich estuarine hinterland of Venta Icenorum and the North Sea approaches to East Anglia. Its exceptional preservation makes it, alongside Portchester and Pevensey, one of the most informative survivors of late Roman coastal defence in Britain.
Excavations by Charles Green (1958–61) and later work by the Norfolk Archaeological Unit revealed timber buildings inside the fort, evidence of late Roman occup
