Flitwick Castle

Flitwick Castle was an 11th-century castle located in the town of Flitwick, in the county of Bedfordshire, England. It now exists only as ruins, reduced to little but an earth mound.
It was a small, timber Motte-and-bailey castle, surrounded by a moat. The castle was mentioned in the Domesday Book, in 1086, as being under the ownership of William Lovet, a Norman. Lovet had displaced Alwin, who had been the Saxon owner of Flitwick prior to the Norman Conquest.
The earthwork remains of the castle are on what is now a public green space known as Temple Field or Mount Hill. The ditches have been filled in and the mound is now about high. The name Temple Field takes its name from the nearby church. The site is a Scheduled Monument.
