Your guide to Martello Towers in the UK and throughout the world.

Martello Towers In Jersey & Guernsey

Jersey

The British built eight true Martello towers in Jersey, three between 1808 and 1814, and five between 1834 and 1837, one of which, L'Etacq, the German occupation forces destroyed during World War II.
The three original towers are:

Icho Tower (1811)
Portelet Tower (1808)
La Tour de Vinde (AKA Noirmont; 1808–1814)

The four surviving, later towers are:

Lewis Tower (AKA St Ouen 1; 1835)
Kempt Tower (AKA St Ouen 2; 1834)
La Collette Tower – Absorbed into the 19th-century artificers' barracks and workshops
Victoria Tower (1837)

In addition, there are a number of towers in Jersey (the Jersey Round Towers), that are frequently referred to as Martello towers, though they are not Martellos. They were built in the late 18th century, ie, before the Martellos, and differ from them in a number of ways. One may think of them as precursors, like the Genoese towers they resemble.

Guernsey

There are three  Martello towers in Guernsey, all built in 1804: Fort Grey, Fort Hommet and Fort Saumarez.

In addition, there are a number of earlier towers in Guernsey (the Guernsey loophole towers), that many people refer to as Martello towers, though they are not Martellos. They were built in the late 18th century, i.e., before the Martellos, and differ from them in a number of ways. One may think of them as precursors, like the Genoese towers they resemble.

Lastly, Bréhon Tower, built in 1856, is an oval tower that represents the final evolution of the Martello tower.
