St Mawes Castle is one of the best-preserved of Henry VIII’s coastal artillery fortresses, and the most elaborately decorated of them all. Built between 1539 and 1545 to counter an invasion threat from Catholic France and Spain, this fort, along with its sister, Pendennis Castle, guards the important anchorage of Carrick Roads on the Fal estuary. Other coastal forts built during this period include Portland, Deal and Walmer Castles.

The clover-leaf shaped St Mawes Castle was originally surrounded by octagonal outer defences, and was designed to mount heavy ‘ship-sinking’ guns. The castle’s fine state of preservation is due to the fact that it was little developed after its completion.

After falling to Civil War Parliamentarian forces in 1646, the castle remained neglected until being partially re-armed during the 19th and early 20th centuries.
