Plac Kościelny is one of the most characteristic places in the history of the Łódź ghetto. Two neo-Gothic towers of the Church of the Assumption of the Blessed Virgin Mary rise above the square. During the occupation, a warehouse was located there, where the stolen Jewish property was kept, and after 1942 - things left behind by the Jews murdered at Chełmno on the Ner. The Church was called a "White Factory" by the inhabitants of the ghetto - it was filled with feathers from bedding looted by the Nazis from the Jews of the Litzmannstadt Ghetto and ghettos in towns near Łódź. Buildings around Plac Kościelny housed institutions important for the functioning of the ghetto. A bridge over Zgierska St. connecting the two parts of the ghetto (featured in the archival photographs) was located near the entrance to the temple. Opposite the church (at Lutomierska St.) the Jewish police station was located.
Number 4 Plac Kościelny was the address of the following departments: Population Registration Department, including the Housing Office, the Registry Office, Department of Statistics and Archives - it was here that "The Chronicle of the Łódź Ghetto" was created, a document which is one of the most important sources of information on Jewish people during World War II. The Chronicle was created by the Jews of Łódź, including Stanisław Cukier-Cerski, , Bernard Ostrowski and Abraham Kamieniecki, as well as Jews who had been deported to the Litzmannstadt Ghetto in 1941, such as Oskar Singer (who supervised the work on the "Chronicle" from April 1943), Bernard Heiling, Oskar Rosenfeld from Prague and Alice de Buton from Vienna. The Department of Statistics employed photographers, including Mendel Grossman and Henryk Ross; they took thousands of photographs of the Łódź ghetto, providing us with an opportunity to learn about the everyday life in the closed area. Until September 1942, the building also housed a Rabbinical College.
The parish house at 8 Kościelna St. a police station of the German criminal police (kripo) was located, called the "red house". It was a particularly grim place where the ghetto residents were imprisoned, beaten and tortured.
