MARTELLO TOWER, Aldeburgh
The largest and most northerly of more than 100 Martello Towers built from Sussex to Suffolk to help defend England from the French. Aldeburgh's tower is unusual because it is quatrefoil in shape - four towers in one, designed to take 4 guns. It was built between 1808-1812. Derelict by the 1970s, it was restored by the Landmark Trust and is now managed by them as a holiday let. It is not generally open to the public so please respect people's privacy is you want to see it from the outside. It sits just a few minutes walk south of Aldeburgh, on the shingle spit of Orford Ness between the River Alde and the North Sea.
