Sandown Castle was one of Henry VIII's Device Forts or Henrician Castles built at Sandown, North Deal, Kent as part of Henry VIII's chain of coastal fortifications to defend England against the threat of foreign invasion. It made up a line of defences with Walmer Castle and Deal Castle to protect the strategic stretch of coast known as the Downs. These three castles were known as Castles of the Downs. It has been partially demolished by the sea, but originally it would have been identical to Walmer Castle in construction.
