Red Sand Forts

The Red Sand Forts comprise seven concrete and steel structures rising above the water of the Thames Estuary and connected by metal walkways. The towers form a military complex with multiple levels serving different functions.

The British Army built these fortifications in 1943 to protect shipping lanes against German air attacks during World War II. Equipped with anti-aircraft artillery, they served maritime defense during a critical phase of the conflict.

In the 1960s, pirate radio stations like Radio 390 broadcast from these towers and reached large audiences along the British coast. The towers became symbols of rebellion against strict radio regulations of that era.

Visiting requires a boat trip out to the estuary, so arrange tours or private providers in advance. The structures are viewable from outside, but direct approach depends on current conditions and local regulations.

The metal structures of the towers have created artificial reefs over the decades, attracting fish populations. Divers and nature enthusiasts sometimes visit the site because of these unexpected underwater habitats that have developed around the structures.
