This small market town has a remarkable history and was founded in the 10th century by Alfred the Great. He encircled it with strong walls. Its strategic position on the banks of the River Thames persuaded William the Conqueror to built Wallingford Castle which was later destroyed by Oliver Cromwell after a 65-day siege. Earlier, King Henry 11 had held his first parliament in Wallingford in 1154.
The town hall, which stands on pillars, dates from 1670 and is one of many old buildings that have survived the ravages of time. The hall contains a number of important portraits (view by appointment). In modern times the town’s most famous resident was the crime writer Agatha Christie who lived at Winterbrook House.
