The Castle Haven School was built by John Anthony LeCompte Radcliffe for Dorchester County in 1870 because there was no local school for his children to attend. John was paid $500 for the project, losing $60 on the deal. Originally located on the west side of Castle Haven Road nearby, the school operated from 1870 until 1924. After the school closed, George L. Radcliffe, the builder's son, bought the lot that contained the school building and in August 1930 had the building moved to the Spocott property. The schoolhouse was then moved to the windmill complex in 1986.
