Zouches Manor (also Zouches Castle) was an Anglo-Saxon moated manor in Fulbourn Fen, a Site of Special Scientific Interest in the village of Fulbourn, Cambridgeshire, England.
[1] The manor was built by Alan la Zouche, Earl of Brittany (the same family that held Ashby-de-la-Zouch in Leicestershire) [2] in the 13th century on an earlier site.
The moat ditch and platform are likely to have been constructed in the 12th or 13th century, obscuring who exactly built the structure.
The Zouches and their successors continued to hold Zouches Manor of the honour of Richmond into the 15th century in socage, rendering two gilt spurs yearly into the 15th century.
The location commands access to the village and the upland areas from The Fens and was probably chosen to defend against attack from the Fens during troubles such as the First Barons' War in the 13th century and the battles between the Romano-British (to the south), Anglo-Saxons (in East Anglia) and Belgae & Norman invaders.
