Most of the site is under modern housing but the southern gate and a building have been put on show.
The Romans arrived in Caister-on-Sea in the 1st century AD (built around AD 200). It was occupied until the end of the 4th century, when Roman forces were withdrawn from Britain. The name Caister-on-Sea derives from the Latin 'castra' meaning castle being part of a line of Saxon Shore forts. To the west of the naval/army base, a civilian settlement was established. It was situated on an island, with the River Bure and Yare/Waveney emptying into the North Sea. Seven miles to the south Burgh Castle TG4704 : Roman Walls at Burgh Castle guarded the southern part of the estuary. Caistor on Sea fort was much larger, housing the army and sailors. It is also thought it supplied Burgh castle (via the sea) as it is possible a Roman road connected this site with Caistor St Edmund near Norwich TG2303 : Venta Icenorum - north wall.
