One of the famous sites in York is Clifford's Tower. Clifford's Tower was originally part of a castle built by the Romans. One of its most tragic stories involves a group of Jews who were being persecuted. They barricaded themselves inside the tower. When they realized that they weren't going to escape, rather than fall into the hands of the Romans, they committed suicide. The few that survived were later executed by the Romans. This is a view of the Tower from the base.
