Folly fort

The main characteristic of a folly fort was that it was built on the water, very close to the edge, very small, and exclusively for military defense with no intention of being used as normal living quarters.

They were really defense fortifications rather than what were called "forts" at the time, which were on land and much larger.

Today two skyscrapers stand in the same place, which is at the water's edge and no longer an island due to land reclamation.

The British captured it on 6 November 1856 in an intense, one-hour action during the second Opium War.
