Capeston Rath is a bivallate in land promontory fort occupy ing a gentle southeast-facing slope at c.30m above sea level. It is a blunt promontory, with fairly steep slopes to the south and east. The defences comprise a 145m long curving line on the north and west sides of the promontory, enclosing an area c.40m N-S and 65m E-W. The inner bank stands 2m above the interior of the fort and 2m above the ditch. The outer bank stands 3m above the ditch on its interior side and 5m above the outer ditch. Large stones on the inner bank suggest a revetment wall. The entrance seems to be at the southern end of the defences on the west side. A detached mound to the southwest of this possible entrance may be a medieval motte or a bastion/barbican entrance arrangement. The interior is under pasture and the ramparts under scrub. Badger setts in the banks are damaging the site. There is a recent gap through the defences for vehicular access to the interior on the north side.

Gatehouse Comments

A slight suggestion of medieval re-use including the suggestion of the making of a mound is not particularly convincing.
