Tilbury Fort

Tilbury Fort is a star-shaped fortress on the north bank of the Thames with angular bastions and water-filled moats, supplemented by two tiers of gun emplacements along the riverbank. The site includes underground gunpowder magazines and casemates that demonstrate the evolution of fortification design across multiple centuries.

The fort started as a small blockhouse in 1539 under Henry VIII to protect against French threats, but was completely redesigned from the 1670s onward under Sir Bernard de Gomme, gaining its distinctive star shape. This transformation made it one of the most advanced fortifications of its era.

The fort reveals how military design changed over time and remains a place where visitors can observe how a defensive fortress actually functioned. The layout and structures show the practical demands of protecting a strategic waterway.

Access is by marked pathways across the grounds, with underground passages open to visitors where sturdy footwear is recommended. Visiting in dry weather is ideal, as paths can become slippery otherwise.

The fort is remembered as the place where Queen Elizabeth I delivered a speech to troops in 1588 as they prepared for the expected Spanish Armada invasion. This moment remains anchored in English history as a symbol of resolve during times of danger.
