Marisco Castle was originally a mid 13th century stone shell keep and bailey fortress, founded by King Henry III. Standing on a prominent cliff-top site, in 1643 during the Civil War the royalist Thomas Bushell rebuilt the castle. In the 1850s, the ruinous rectangular keep was repaired and its interior converted into fishermen's cottages, built around a central courtyard. Including subsequent additions the present castle comprises of a keep, a parade ground revetted with stone, a northern curtain wall, an outer ditch on the north and west sides and a storage cave to the east. Visit pending.
