"Pevensey Castle is associated with
the earliest history of Britain. Upon its site
stood the Roman Camp of Anderida, oval in
shape, and obviously adapted to surface configuration. It is the reputed site of the landing of
Caesar. The British occupied it when the
Romans left, and here occurred the great massacre
by the South Saxons under Ella in 477. In
1066 William I. landed at Pevensey and erected
one of his portable wooden castles, probably
within the Roman Camp." Extract from "British Castles" (Open Library)
