St Andrew's Castle was an artillery fort constructed by Henry VIII near Hamble-le-Rice, Hampshire, between 1542 and 1543. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended Southampton Water near the Solent. St Andrew's comprised a keep and a gun platform, protected by a moat. The castle was decommissioned in 1642 during the English Civil War and has been largely destroyed through coastal erosion.
