We all know what the Nazis did to the Jews during WW II but I was not aware that it happened in Rome as well. The plaque in the upper right is a reminder that on October 16,1943, the Nazis brought trucks to this spot in the Jewish Quarter and rounded up thousands for deportation to Auschwitz.
This 150MM German gun is located on a cliff near the town of Longues-sur-Mer overlooking the beaches of Normandy and were used to fire on the ships during the invasion. Town mayors, after the war, were allowed by the government to remove any metal, equipment, food, materials, etc. and sell/use the items for the good of the people. The mayor of Longues sur Mer decided to leave the guns intact as a monument to the hostilities.
