As part of the Operation Overlord deception operation known as Operation Fortitude, a fake oil dock was created at Dover. The architect Basil Spence was called upon to design it. Constructed from camouflaged scaffolding, fibreboard and old sewage pipe, the fake facility spanned 3 acres (1.2 ha) and included fake versions of pipelines, storage tanks, jetties, vehicle parks and antiaircraft emplacements.
