Sleaford Castle

Sleaford’s Castle grounds are a popular area of public open space and now the subject of a major research project coordinated by the Sleaford Castle Heritage Group. Archaeological and historical research is expected to continue for several years.

Sleaford Castle was built by the Bishop of Lincoln, Alexander de Blois between 1123 and 1139 and held by the Church for over 400 years. The castle fell out of use in the mid-1500’s and into disrepair. It was substantially demolished in the following century. Little remains to be seen today apart from earthworks and a small remnant of a tower in the north-eastern corner of the riverside castle site.
