1911 Encyclopædia Britannica/Anderida

ANDERIDA, an ancient Roman fort at Pevensey, near Eastbourne in Sussex (England), built about A.D. 300 as part of a scheme of land-defence against the Saxon pirates; repaired, probably by the great Stilicho, about A.D. 400; and after the Norman Conquest utilized by William the Conqueror for a Norman castle. Its massive Roman enceinte still stands but little damaged.
