The oldest ghost?

The city of York was an important centre for the Romans, who built a camp where York Minster stands today. During recent excavations under the Minster a man who was working there saw half a Roman soldier marching towards him. As the soldier came nearer he saw the other half below the level of the floor. Then he understood that the man was walking at the level of the old Roman Road. The soldier walked past and slowly disappeared.

Most ghosts seem to die after about four centuries, but the ghost of the Roman soldier in York is nearly nineteen hundred years old!
