Rusting valve and pipework inside the surviving WWII sea-flame barrage hut at Seaford, East Sussex.

A close-up of the heavily corroded valve and metal pipework surviving inside the wartime hut near Marine Parade, Seaford, East Sussex. The structure is believed to be associated with the Second World War sea-flame barrage system, designed to release and ignite oil along the coastline in the event of a German invasion. The surviving machinery provides a fascinating glimpse of the engineering associated with Britain’s extraordinary coastal defence preparations.
