Gravesend blockhouse is a Tudor artillery fortification constructed in the 1540s under Henry VIII's coastal defence programme. The structure served to protect the Thames estuary and the approaches to London, forming part of a chain of strategically positioned gun emplacements along the Kent coast. Built in brick and stone, the blockhouse originally featured gun platforms designed to mount cannon for defence against invasion during the period of heightened military tension with France and the Holy Roman Empire. Though substantially altered and reduced in height during subsequent centuries, the surviving remains preserve evidence of Tudor military engineering and continue to illustrate the technological response to early modern threats to national security.
