3/5 pl. Grzybowski Street. The All Saints' church.
The church was built between the years 1883-1892.
It was slightly damaged during the siege of Warsaw in September 1939. During the occupation it was known as one of three Christian churches to be situated on the ghetto area and help Christians of Jewish origin who had been made live in the ghetto. During the Warsaw Uprising 1944 the church was controlled by the Polish people, which meant constant threat of attacks and damages. On August 17 during bombing 30 people lost their lives. After the Uprising only building walls and cellars survived. The equipment, including altars, paintings and organs, was destroyed.
The reconstruction lasted till the year 1979.

- commemorating the Home Army soldiers of IV unit "Gurt" of the I District Warszawa Śródmieście;
