Highdown Hill is a small hill 226 feet high that stands just north of Ferring on the West Sussex coast and is seperated from the main bulk of the South Downs to the north.
It has had much use in Prehistoric times with a settlement in the Bronze age, fortification in the Iron age, a Roman bath house and a Saxon cemetary, allegedly the burial place of the Saxon King Ælla after the battle at Mount Badon with King Arthur in 516AD
