About a 40 minute drive from Avebury Stone Circle lies Uffington ‘Castle’, which occupies the summit of Whitehorse Hill. This is a rare and outstanding example of a large Iron Age hillfort. The famous White Horse is the oldest chalk-cut hill figure in Britain, perhaps over 3,000 years old. Nearby Dragon Hill, a natural mound about 10 meters high, is named for its association with the legend of St George.
