Jaywick Martello Tower

They were constructed to defend the country against invasion by Napoleon Bonaparte and his armies.

In total, 103 Martello towers were built between 1804 and 1812,[3] 74 were built between 1804 and 1808 along the Kent and Sussex coast from Folkestone to Seaford,[4] and 29 along the east coast between Point Clear near St Osyth and Aldeburgh from 1809 to 1812.

Three other east coast towers are known as AA, BB and CC.

The roof held three sea-facing cannon, usually one heavier gun flanked by two smaller howitzers.

[7] In 2005 the tower opened as a gallery space and arts venue managed by Essex County Council.
