English Heritage: Deddington Castle
The earthworks forming Deddington Castle lie in a rural location to the south-east of the village of Deddington. No stonework is visible above ground today, but the site is nevertheless a striking one owing to the scale of the earthworks and the size of the enclosed area.
This castle was the Oxfordshire base of Odo of Bayeux, half-brother of William the Conqueror and a powerful man in England after the Norman Conquest.
Deddington is located 17 miles north of Oxford. There are a number of nearby bus routes, and King's Sutton train station is 5 miles away.
