What is recorded here

Folkingham Castle is a water-locked rectangular island where moats replaced hills, giving Gilbert de Ghent a defensible gift from William the Conqueror and later becoming a Beaumont seat. John Leland found it falling into ruin in 1535, and its stones may have been reused locally after Civil War damage. The earthworks still mark a place where water, not height, was the wall.

The National Heritage List for England records Folkingham Castle as a scheduled monument. The saved point comes from the centre supplied by the official record. Listing does not by itself mean that the public may enter the place.

Folkingham Castle was built in the 11th century, likely by the de Fiennes family, and later held by the powerful D'Albini family, who were key Norman lords in Lincolnshire. It is important as a rare example of a motte-and-bailey castle that provides insight into early Norman military architecture and land control in post-Conquest England.
