Tilbury Fort is the best-preserved example of a 17th-century bastion-trace fortification in England, designed to protect the Thames Estuary. The site features a sophisticated pentagonal layout with double moats and an array of brick-vaulted magazines. It served as a strategic defensive point from the 16th century through the Second World War. Visitors explore the artillery bastions, the 17th-century chapel, and the officer’s barracks. The structure showcases the evolution of military engineering, including adaptations made to counter modern naval threats in the 19th and 20th centuries. It is managed by English Heritage as a historical site and includes a gift shop. The fort remains a significant landmark for maritime history in the Thames Gateway region.
