This is a Grade 1 listed building protected by law*.


Remains of a Roman-Saxon shore fort, probably built in the late C3 and evacuated in the early C5. The fort walls survive on three sides (north, south and east) and reach a height of c.4.6m and up to 3m thick; they are of coursed flint facing a concrete rubble core. At every 5-6 courses of flints are 3 courses of brick, giving a striated appearance to the walls. At the corners and at the centre of the shorter sides (north and south) are bulbous drum bastions which were probably added in C4. The wall on the west has collapsed and is no longer visible. The remains of the late C11 Norman motte and bailey occupied the south west quadrant of the fort, where it was visible at one time as a large earthen mound encircled by a ditch. The mound was partly removed circa 1770 and completely levelled in 1839, and the ditch was infilled, although it survives as a buried feature and has been recorded as a crop mark enclosing an oval area measuring circa 72m north-south by 53m east-west. A section excavated across the ditch on the east side established that it is circa 4m deep and that the lowest levels of fill are waterlogged. On the south east side a breach circa 18m wide in the south curtain wall marks where the ditch cuts through, and traces of the southern edge of the mound above the scarp of the inner edge of the ditch remain visible against the outer side of the wall to the west of the breach. Approximately a quarter of the area formerly covered by the mound was also excavated and found to contain several large, clay-filled pits, identified as foundations for part of a timber sub-structure to support the tower, also of timber, which stood on top of the mound. The remainder of the fort, to the north and east of the motte, was adapted for use as the bailey of the castle. A north-south bank, remains of which were observed in the excavations at the north west corner, is thought to have been constructed at this time to block the gap on the western side of the fort left by the collapse of the north end of the original Roman wall on that side. The broken western end of the north wall was reinforced by a large earthen mound heaped against its outer face up to 6m high above the falling ground level to the north. Post-Conquest occupation of the fort is confirmed by finds of C11/C12 pottery. (Derived from Scheduling Report)

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
