The Day the Canal Vanished In 1978, workers dredging the Chesterfield Canal uncovered a heavy iron chain, unaware it was still attached to a hidden maintenance plug from the 1700s. When they lifted it, centuries of engineering suddenly gave way. An entire section of the canal drained in moments, stunning everyone on site and turning a routine job into an unforgettable historical surprise. #HiddenHistory #EngineeringSurprise #CanalLife #UnexpectedMoments
