St Mawes Castle (Cornish: Kastel Lannvowsedh) is an artillery fort constructed by Henry VIII near Falmouth, Cornwall, between 1540 and 1542. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the Carrick Roads waterway at the mouth of the River Fal. The castle was built under the direction of Thomas Treffry to a clover leaf design, with a four-storey central tower and three protruding, round bastions that formed gun platforms. It was initially armed with 19 artillery pieces, intended for use against enemy shipping, operating in partnership with its sister castle of Pendennis on the other side of the estuary. During the English Civil War, St Mawes was held by Royalist supporters of King Charles I, but surrendered to a Parliamentary army in 1646 in the final phase of the conflict.
The castle continued in use as a fort through the 18th and 19th centuries. In the early 1850s, fears of a fresh conflict with France, combined with changes in military technology, led to the redevelopment of the fortification. The out-dated Henrician castle was turned into a barracks and substantial gun batteries were constructed beneath it, equipped with the latest naval artillery. In the 1880s and 1890s an electronically-operated minefield was laid across the River Fal, operated from St Mawes and Pendennis, and new, quick-firing guns were installed at St Mawes to support these defences. After 1905, however, St Mawes' guns were removed, and between 1920 and 1939 it was run by the state as a tourist attraction.

St Mawes (Cornish: Lannvowsedh) is a small town opposite Falmouth, on the Roseland Peninsula on the south coast of Cornwall, England, United Kingdom. It lies on the east bank of the Carrick Roads, a large waterway created after the Ice Age from an ancient valley which flooded as the melt waters caused the sea level to rise dramatically, creating an immense natural harbour, often claimed to be the third largest in the world. It was once a busy fishing port, but the trade declined during the 20th century and it now serves as a popular tourist location, with many properties in the town functioning as holiday accommodation. The town is in the civil parish of St Just in Roseland.
A year-round ferry provides a service to Falmouth, which is less than a mile away by boat, but due to its proximity to the Fal estuary it is some 30 miles away by road. The Place Ferry links the South West Coast Path and operates from Good Friday to the end of October.
St Mawes was a rotten borough in Cornwall, England. It returned two Members of Parliament (MPs) to the House of Commons of England from 1562 to 1707, to the House of Commons of Great Britain from 1707 to 1800, and to the House of Commons of the United Kingdom until it was abolished by the Great Reform Act in 1832.
The borough consisted of the manor of St Mawes, a decayed fishing port and market town in the west of Cornwall. Like most of the Cornish boroughs enfranchised or re-enfranchised during the Tudor period, it was a rotten borough from the start.
The right to vote rested with the portreeve and "resident burgesses or free tenants", making it essentially a scot and lot borough (there were 87 voters in 1831), but the control of the "patron" was entirely secure. In practice the patron always worked in close collusion with the Crown, and the members returned were generally court nominees throughout the borough's existence. In the 1760s the Boscawen family (the Viscounts Falmouth) were considered to have the main influence over the choice of one member and Robert Nugent over the other; by the time of the Great Reform Act, the patronage had passed to the Marquess of Buckingham.
