Explore the Historic Humber Forts from Cleethorpes Beach

Standing on Cleethorpes Beach, you’ll be treated to striking views across the Humber Estuary, where the iconic Bull Sand Fort and Haile Sand Fort rise from the water. These historic World War I-era structures were part of the east coast’s defensive network, built to control access to the Humber and protect a designated ‘safe muster area’ for naval convoys.

Bull Sand Fort, the larger of the two, was constructed on a submerged sandbank over a period of four years. Its completion came just after the war ended, but it remained a marvel of military engineering. Designed to accommodate 200 men, it even had fresh water pumped in from a natural stream beneath the seabed. During World War II, it was reactivated and armed with quick-firing guns, serving as a strategic post for the East Riding Heavy Artillery Regiment.

Haile Sand Fort, positioned on a hexagonal concrete foundation, became operational in 1917. This four-story, circular fort featured light steel armor and a two-story central observation tower, originally housing two quick-firing guns. Like Bull Sand Fort, it was reoccupied in 1939 for coastal defense.

Both forts were decommissioned in 1956 and have since been abandoned, but their rugged silhouettes remain a reminder of the area’s wartime history. Visible from Cleethorpes on clear days, they are a fascinating glimpse into the past and a unique sight for visitors to the Lincolnshire coast. Whether you’re walking along the sands or simply enjoying the view, the Humber Forts are a must-see part of Cleethorpes’ rich maritime heritage.
