Today was crazy.  we went to Sachsenhausen.  It was a Nazi concentration camp.  It was also used as a special camp by the Soviets after the war.  They didn.t want the world to know some of the stuff they did so they distroyed most of the camp.  It was crazy to see how big the complex actually was.  it blew me away.  The tour was 6 hours long.  it was very intense.  I am so glade i went though.  but i am supper tired. tomorrow we are going to just walk around Berlin one more time before we leave on the night train.
