Surviving WWII Type 24 infantry pillbox at Barcombe Mills, built to defend the River Ouse crossing in 1940.

A surviving Second World War Type 24 infantry pillbox at Barcombe Mills, near Lewes in East Sussex. Constructed in 1940 as part of Britain’s anti-invasion preparations, the pillbox was positioned to defend a strategically important crossing of the River Ouse. Its irregular hexagonal design provided firing positions covering different approaches. Together with a nearby anti-tank gun emplacement, it formed part of the inland defensive network intended to delay a possible German advance through Sussex.
