About

Sleaford Castle is a medieval castle in Sleaford, Lincolnshire, England. Built by the Bishop of Lincoln in the early 1120s, it was habitable as late as 1555 but fell into disrepair during the latter half of the 16th century. Two English monarchs are known to have stayed at the castle, King John and Henry VIII.
