Dating back to 1071, Oxford Castle is known for sightings tied to its long history as both a fortress and a prison. The most reported figure is Mary Blandy, executed here in 1752, whose pale apparition has been seen on the castle mound and near the Debtors’ Tower, often accompanied by the scent of perfume. Former inmates are said to appear in the underground crypt and D-Wing, where visitors feel sudden cold gusts, hear dragging footsteps, and report whispers in empty cells. With nearly a millennium of conflict, imprisonment, and execution, Oxford Castle is regarded as one of Oxfordshire’s most intensely active haunted landmarks.
