Gravesend blockhouse is a coastal artillery fortification constructed in the early sixteenth century, forming part of the defensive scheme initiated by King Henry VIII to protect the Thames estuary and London from naval attack. The structure was built circa 1540 as a gun tower capable of mounting cannon to command the river approaches, positioned strategically on the Kent shore near the town of Gravesend. Though substantially modified and rebuilt in later centuries, particularly during the Napoleonic Wars period when its defences were strengthened, the blockhouse retains evidence of its Tudor origins in its masonry construction and basic plan. The fort remained an active military installation well into the modern period, serving successive generations of national defence requirements along one of England's most strategically important waterways.
