Before World War II, Warsaw was a hub of Jewish life in Poland, home to around 380,000 Jews – nearly a third of the city’s population. In October 1940, the Nazis forced the Jewish population into the Warsaw Ghetto, a space of just 1.3 square miles (3.4sq km).
Over 265,000 Jews were deported to the Treblinka extermination camp, while thousands more perished from starvation, overcrowding and disease. The ghetto was mostly destroyed following the Warsaw Ghetto Uprising of 1943, but a few structures survived, including small sections of the ghetto wall.
