Three Places. Such as they are, Poland, France, and Russia.
In Poland is Auschwitz, one of many World War II death camp established by The Third Reich. Along with Auschwitz, there are Treblinka, Sobibor, and the others.
In France is Oradour-sur-Glane, one of many silent witness of terrifying massacre done also by the same regime, if I may call it regime. There is also the beach of Normandy where the biggest marine assault ever took place.
In Russia is Stalingrad, one of many fierce battles happened during second world war.
Seriously, who would open the first topic of daily post and write about it? Of course the cities mentioned above have recovered from their wound. Why would people go to visit and reminisce the old days?
