Things to see and do Young Island

Accessible from Young Island, the small Fort Duvernette, also known as "Fort Rock", was built around 1800 on a massive rock over 60 m high to protect the village of Calliaqua, an important anchorage for ships calling at the time, where sugar was loaded for English ports.

Two English military garrisons lived in the fort, one forming a first protective rampart 15 m from the summit, and the other at the summit itself. Fort Duvernette still possesses a complete battery of armaments from that period.
