This elevated site, overlooking Dover Harbour was built between 1877 and 1874 as a battery for 3 x 10" rifled muzzle loaders as part of a network of seaward firing batteries. The battery sits on an artificial terrace cut into the hillside just beneath the crest. Its curved trace was constructed between 1874 and 1877, with low visibility in mind, for heavy RML guns in deep concrete emplacements with integral bomb-proofed support buildings. A covered way runs alongside the trace to the rear, beyond which is a secondary cartridge store cut deep into the hillside. The covered way linked the battery with the South Military Road, one of the main service roads on Western Heights. The battery was disarmed by 1902 and remained, probably in care and maintenance, until 1940. At this time, it was brough back into service and extensively remodelled to take three 6-inch guns for coast defence, remaining operational until late in 1944. The flanks of the battery were secured by three pillboxes (TR 34 SW 424, 492 & 493). It was abandoned after the war. (location accurate to the nearest 10m based on available information)
