An anti-Napoleonic circular fort commanding the harbour. Eleven guns on battlements.
This large circular fort was built in 1808 to protect the harbour from a Napoleonic invasion. The casemates (rooms for soldiers, stores and ammunition) now accommodate various military, bygone and maritime collections. The maritime collections and displays include naval navigation equipment, naval uniforms, shipmodels, objects connected with lighthouses and lifesaving and the last Harwich whelk boat.
