Warszawa - Zamek Krolewski

The Royal Castle of Warsaw.  Originally constructed from 1598 through 1619, the Royal Palace or Zamek, The castle was a prominent target of the Germans during the 1939 invasion for its symbolism.  The roof was removed to help decompensation of the building and after the 1944 Uprising the remains of the building were dynamited by the Germans leaving little more than a pile of rubble as they evacuated the city in January 1945. 

The building was rebuilt with donations from the US in between 1971 through 1984.
