Redoubt 4, grade II listed and a designated Scheduled Monument, was built in 1782. It formed part of a group of defensive structures designed to resist French and Spanish attacks while the Royal Navy was engaged in the War of American Independence (1775-1783). The battery had 15 gun embrasures. It was disarmed in 1815, re-armed in 1849 and remodelled in 1887, when the sea-facing wall was strengthened and new gun emplacements and bomb proof accommodation were added. In 1899 the redoubt was renamed ‘Grenville Battery’ and was intended to defend against battleship bombardment.
