Martello tower

Martello towers are small defensive forts built by the British Empire at the time of the Napoleonic Wars. They stand about 40 feet (12m) high (with two floors) and had a garrison of one officer and 25 men. Their round structure and thick walls of solid masonry made them immensely resistant to cannon fire, while their height made them an ideal platform for a single heavy artillery piece, mounted on the flat roof and able to traverse a 360° arc. A few were surrounded by a moat for extra defence.

They took their inspiration (and their name, albeit mutated) from a round fortress, itself part of a larger Genovese defense system, at Mortella Point in Corsica. This had, in 1794, successfully beaten off the attack of two British warships, HMS Fortitude (74 guns) and HMS Juno (32 guns) but was eventually defeated by land-based forces after two days of heavy fighting. The British were duly impressed by the effectiveness of the tower against their most modern warships and copied the design. Between 1804 and 1812 they built a chain of similar structures to defend the south and east coast of England, Ireland and Guernsey to guard against possible invasion from France, as much as the French built similar towers, also used for communication by optical telegraphs (Chappe Telegraph). 105 were built in England, set at intervals along the coast from Seaford, Sussex, to Aldeburgh, Suffolk. Most were constructed under the direction of General William Twiss (1745?1827) and a Captain Ford.

The effectiveness of Martello towers was never actually tested in combat against a Napoleonic invasion fleet. After the Napoleonic threat had passed, England's Martello towers met a variety of fates. Many were taken over by the Coast Guard to aid in the fight against smuggling. Fifteen were demolished to re-use their stonework. Thirty were washed away by the sea, while four more were destroyed by the military in experiments to test the effectiveness of the new rifled artillery. During the Second World War, some Martello towers returned to military service to serve as observation platforms and firing platforms for anti-aircraft artillery. Forty-seven have survived in England, of which a few have been restored and transformed into museums, visitor centres, and galleries, such as Jaywick Martello Tower. Many are privately owned or private residences and the remainder are derelict.
