Fort Borstal is a Napoleonic coastal defence fort located near Gravesend in Kent. Constructed in the early nineteenth century as part of the extensive fortification programme undertaken by the British government to counter the threat of French invasion during the Napoleonic Wars, the fort represents a significant example of early nineteenth-century military architecture. The structure comprises a substantial brick-built fortification designed with gun emplacements to defend the Thames estuary approaches. Though modified and repurposed over subsequent centuries, Fort Borstal remains an important archaeological and architectural record of Britain's coastal defence strategies during the Napoleonic period.
