Old Sarum is a large, cone-shaped hill that rises near Salisbury, in Wiltshire, England. The hill is about 300 feet (90 meters) high and is surrounded with earthworks (walls and fortifications made of packed earth). Old Sarum was fortified in turn by the ancient Britons, the Romans, and the Saxons. It was later the site of a Norman castle, and Bishop Herman founded a cathedral there in about 1072.
