On the north side of the Minster a quiet little street, Chapter House Street, runs along one side of the Treasurer's House, close to the line of an important Roman street (via decumana) which led to the north-east gate of the fortress. The Roman street itself forms the floor of a small cellar inside the Treasurer's House, which is now open to visitors. It was here that one of the strangest stories in York's history began. In 1953 a young local man, Harry Martindale, was working in the cellar when he heard the sound of a trumpet. He turned to see a group of Roman soldiers walk out of the wall and continue past him. Later, he described how the soldiers' legs were not visible below the knee. After being ridiculed Harry stopped telling his story, but in 1954 excavations showed that a series of cobbled street surfaces had built up during and since the Roman period making sense of Harry's claim! The ghostly soldiers were presumably walking on the earliest and deepest street level!
