Originally 103 towers were built between 1805 and 1812 to resist a potential invasion by Napoleon.
29 were built between Aldeburgh and St Osyth Stone between 1808 and 1812 to protect Essex and Suffolk, the rest having been built a few years earlier across the Kent and Sussex coasts. They were built of brick, 13 foot thick on the seaward side, stood about 30 foot high and were equipped with a cannon on the roof. A supporting fort, or Redoubt, was built at Harwich.The largest tower is Martello CC, at Aldeburgh, which is effectively four towers joined together.
St Osyth to Felixstowe towers (A to Q).
Bawdsey to Hollesley towers (W to AA).
