The tower from war to history

A Martello tower is a type of small defensive fort built across the British Empire during the 19th century, in response to the threat of Mediterranean pirates. The Corsicans had built similar towers since the 15th century to protect coastal villages from pirates. However, these towers were replaced with circular towers after the Genoese took over. The Genoese tower at Mortella Point is the inspiration for Martello towers. These towers, standing 40 feet (12 m) high and with walls about 8 feet (2.4 m) thick, were designed to be resistant to cannon fire, with a single heavy artillery piece on the flat roof and a small garrison of 24 men and one officer. While these towers were eventually made obsolete by rifled artillery, many have survived as historic monuments.
