Natasha Williams, English Heritage’s head of historic properties for the Sussex area, said, “As part of the project, the exhibition space in the East Tower at the castle has also been revamped, with new interpretation highlighting how the Second World War gave a strange twist to Pevensey Castle’s history.
“After the fall of France in 1940, Pevensey once more became a potential landing place for an invasion.
“Designated a fortress, its garrison was ordered to defend it to the last man. Observation posts were set up, the perimeter defences were refortified, pillboxes for machine-gun posts were built, and an anti-tank blockhouse was constructed in the mouth of the Roman West Gate.
“The towers of the inner bailey were refitted as barracks for the garrison, which over the course of the war included the Home Guard, British and Canadian soldiers and US Army Air Corps units.
“Through first-hand accounts of international troops, stories told include how the troops climbed the walls for training, running along the tops (sometimes in the dark) and jumping over the gaps in stonework.”For more information visit www.english-heritage.org.uk/visit/places/pevensey-castle
