Castles in Cornwall

  • The Old Blockhouse / Isles of Scilly

    The 16th century Old Blockhouse is located at the southern end of Old Grimsby harbour on Tresco. It was built in the reign of Henry VIII as part of a series of coastal defences to protect against invasion from the French.

  • One of a pair of defensive structures, the other being on the far side of the river mouth in Fowey. The blockhouses were linked by a huge metal chain which could be raised to prevent ships entering the harbour during an attack. Built in 1380 primarily to defend from French and Spanish.

  • St Michaels Mount / Marazion

    Island castle set in the middle of Mount's Bay, just off the coast of Marazion. The Mount is now managed by the National Trust but remains the home of St Aubyn family.
