The first castle in Lydford, was built just after the Norman conquest. It was intended to help control Devon following the widespread revolt against Norman rule in 1068. It was abandoned by the 12th century. The second castle was constructed in 1195 following a wave of law and order problems across England. It included a stone tower with a surrounding bailey, and rapidly became used as a prison and court to administer the laws in the Forest of Dartmoor and the Devon stannaries. In 1342 the castle, still being used as a prison and courtroom, passed to the Duchy of Cornwall, who owned it until the 20th century.
