Bomb Rubble
Hopefully these bombs are defused. After the war the surviving inhabitants of Nuremberg had to remove tons and tons of rubble from destroyed buildings out to the outskirts where it was disposed of in big rubble piles near the Nazi Party Rally Grounds. Short gauge trains were routed right into the downtown to haul the refuse out. In among the rubble live unexploded ordinance was often found. And there are still live ammunition finds occurring today.
