Sirens and church bells sounded in homage to Jewish fighters who perished during the fight in World War II.
The major Jewish revolt began on April 19, 1943, and was finally crushed by Adolf Hitler’s forces around a month later.
Thousands of Jews died in the uprising, and tens of thousands of survivors were sent to death camps.
Polish President Bronislaw Komorowski led commemoration ceremonies at the Monument to the Ghetto Heroes.
Some surviving veterans of the uprising attended the ceremony.
Before the revolt, the Nazis sent around 300,000 Warsaw Ghetto residents to their deaths in camps, while others died from hunger and disease.
