Cliffe Fort

Cliffe Fort is a mid-19th-century military fortification near the Thames featuring casemated gun positions and underground passages. The structure contains ammunition storage chambers and a range of lighting systems integrated into its granite construction.

The fort was built between 1861 and 1870 in response to British concerns about French naval threats along the Thames. It later became involved in testing new torpedo technology for coastal defense systems.

The fort reflects how Britain viewed its coastal defense needs in the 19th century and the strategic importance of the Thames to national security. Its design shows how military engineers adapted structures to work on marshy ground.

The fort sits on private property and is not open to the public for visits. The site contains flooded areas, making close approach difficult and potentially unsafe.

The fort housed one of Britain's early Brennan torpedo installations, an innovative remote-controlled weapon of its time. This technology represented a leap forward in how coastal defenses were being modernized.
