St Mawes castle is a Device fort built between 1540 and 1545 as part of Henry VIII's south coast fortifications. Together with its sister castle at Pendennis, St Mawes defended the approaches to Carrick Roads, one of the largest natural harbours in the country. It was built just above an earlier fortification dating to the late 1530s. The building work was supervised by Thomas Treffry, who supervised the building of Pendennis Castle at about the same time. St Mawes was constructed with a central tower overlooking three huge circular bastions attached on the sides in a clover leaf pattern, providing a wide area for gun placements, with gun ports covering every angle of approach to the estuary.
