Flitwick Castle in the Bedfordshire town of Flitwick is a motte and bailey castle that was constructed toward the end of the 11th Century. It is thought that the castle was constructed on the orders of William Lovet, who held the manor of Flitwick after the Norman Conquest.
The castle is mentioned in the Doomsday Book and was constructed out of timber, as were many early Norman castles.
Today, earthwork remains are all that are left of this castle. These earthwork remains are located in a public open space know as Temple Hill or Mount Hill.
The remains of the castle can be visited during any reasonable daylight hour.
