Guide to Martello Towers

Martello Towers are small forts that were first built at the beginning of the 19th Century along the coast in several countries belonging to the British Empire (and elsewhere in the world) in order to ward off an attack from Napoleon. Today, a number of these towers are still standing in various parts of Suffolk.

Appearance and Uses of the Martello Towers

Martello towers - also known simply as Martellos - are generally around 40 feet in height and have an unusual rounded shape with thick walls of solid stonework. The round, curved appearance of the Martellos was implemented to enable the garrison of soldiers and officers that inhabited them to have complete 360 degree views.

The wide roofs made an ideal stage to hold a cannon, which was placed on a pivot and so also to rotate 360 degrees. The thick, stone walls made the Martello a sturdy platform, and also highly resistant to enemy cannon fire. Some of the Martellos also had a moat around them as a further protection from attack. Often, a single doorway is found 5m off the ground that could only be accessed by a removable ladder.

British Martellos were typically 2 or 3 floors high, and a base of 24 men plus 1 officer occupied them. The men lived on the first floor which was divided into separate rooms for cooking and sleeping. There was a cistern within the fort to provide the men with water, which was refilled with rain via an internal drainage system that linked to the roof. A fireplace was built into a wall on the first floor for heating, bathing and cooking. The ground floor was used as a stock room, where supplies of ammunition plus food & drinking water were kept.

Origin of the Martello Towers

These curved forts were inspired by the Genovese defence system at Mortella Point in Corsica, which were first built in 1565. The Corsicans had originally built these towers on the coast of the island in order to protect their villages from pirates. The towers and their watchmen were paid for by local villagers, and whenever a pirate threat was seen, the watchmen would alert the villagers by lighting a fire on the tower's roof. Although the pirate threat subsequently dwindled, the Genovese built a newer generation of circular towers that were used to ward off later foreign invasions.

In 1794, the fort at Mortella Point was overthrown by the land-based forces British after two days of heavy fighting. It is thought that the British were able to capture the fort because the Corsican's cannons were largely aimed sea-ward and unable to change direction. Despite this overthrowing, the British were greatly impressed with the fort and felt that it could be a great asset if defended correctly, and so went on to imitate the design. However, they spelled the name wrong, using "Mortella" as "Martello", which translates to "hammer" in Italian. When the British withdrew from Corsica in 1803, they blew up the tower - after attempting to do so for a very long time! - leaving it in an unusable state.
