BURGH CASTLE
Gariannonum Roman Fort (Burgh Castle)
10.6.53
I
Roman fort. Probably 260-280 A.D., evacuated c.407-8. Subsequently used as Saxon settlement. Norman motte and bailey castle constructed at south-west corner in late C11, completely removed 1839. Flint, brick and concrete. Roughly quadrangular. North, east and south walls survive. Traces of foundations of west wall discovered during excavations of 1958-62. Walls of coursed flint facing to concrete rubble core. Every 5-6 courses of flints are three courses of bricks, giving striated appearance to walls. At corners and at centre of shorter sides (north and south) are bulbous drum bastions, standing away from walls at base and linked to walls at top. They are solid. Two further bastions are symmetrically placed in east wall flanking central main gateway. Gateway is now only a jagged hole. The bastions are later additions, probably C4. Scheduled Ancient Monument, County number 399.
