Holinshed tells us that "into Peuenseie hauen diuerse waters doo resort," but soon after his time the inning was complete and Pevensey had ceased to have a haven at all.

They are of immense solidity, over 12 feet thick, with a core of rubble flint and faced with small stones of very neat masonry ; there are a plinth of green sandstone and three string-courses, the upper one of brick. To secure their permanence on marshy soil elaborate precautions were taken, piles were driven, huge timbers laid across in places, foundations of puddled clay, rammed chalk and of a flint concrete were supplied, but in spite of it all about a third of the circuit has fallen and much more would have gone but for modern support. At intervals are apsidal towers, two of these flank the principal entrance ; on the western side there were three other gates, the north one having the curious arrangement of a curved passage through the wall, which can be seen close to where a large section has fallen. A bank of clay against the walls within may possibly be a relic of the earthworks, though in the excavations carried out under the direction of F. L.
