Erected shortly after the Norman Conquest, by Roger de Montgomery in 1067, Arundel Castle was to protect the gap that had been carved by the River Arun through the South Downs.

A large castle, of traditional motte-and-bailey design, with the motte 70 feet high and the baileys extending north and south when originally constructed. The buildings today rest on 12th century foundations and are predominantly from the late 1800s
