During the Nazi occupation there were two heroic uprisings: First, the Jewish Ghetto Uprising. Then, about a year later, the entire city rose up against the Nazis in the Warsaw Uprising. As more Jewish people were moved in from the countryside, Warsaw’s ghetto was soon the miserable home of well over a million people. Ghetto Heroes Square — now surrounded by bland Soviet-style apartment blocks — marks the heart of what was the Jewish ghetto. But the Nazis regrouped, and brutally put down the Warsaw Uprising.
