Built between 1540 and 1542 as part of Henry VIII's coastal defences, St Mawes is one of the best-preserved Tudor artillery forts in the country, its clover-leaf plan largely unaltered since. It sits opposite Pendennis Castle across the Carrick Roads - reviewers often pair the two in a single day - with a small beach next to the overflow car park.

History

Henry VIII · 1540

Henry VIII commissioned this clover-leaf artillery fort between 1540 and 1542 under Thomas Treffry's supervision to guard Carrick Roads and counter French invasion threats. The fort featured a central tower and three round bastions designed for cannon placement, initially carrying 19 artillery pieces. It saw action during the English Civil War, was upgraded multiple times, and served again in the Second World War before becoming a heritage site.
