What is recorded here

Bishop Alexander of Lincoln raised Sleaford Castle in the 1130s as a formidable administrative centre, complete with corner towers, a central keep and a double moat fed by the River Slea. Successive bishops occupied the fortress for over four centuries until Bishop Holbeach transferred it to Edward, Duke of Somerset in 1547, after which men stripped its stones for other builds. That greedy dismantling reduced a grand medieval stronghold to grassy earthworks and a single fragment of the north eastern corner tower.

The National Heritage List for England records Sleaford 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.

Sleaford Castle was built in the 11th century by the de Sleaford family, likely following the Norman Conquest. It is remembered as an important medieval stronghold and is now a scheduled monument due to its historical and archaeological significance.
