The Rear Synagogue had been used for worship purposes until the 1920s, then it was a leather storeroom and, after World War II, it served as a fruit and vegetable store. It was not until 1989-1997 that it underwent an extensive reconstruction and it was opened to the public as a museum. In 2003, it was listed as a UNESCO World Heritage Site as part of the Jewish Quarter. In the women´s Gallery of the synagogue, there is an exhibition of the Jewish ceremonial object (including a Torah scroll) and a unique model of the Jewish Quarter at a scale of 1:100, capturing the state of the quarter in 1850.

Seligmann Bauer House, standing next to the Rear Synagogue, presents a unique exposition of the Jewish family housing in the interwar period. On the ground floor there is a grocery store, on the first floor a kitchen, a bedroom, and a butcher's shop in the yard. The attic of the building is adapted to a lecture hall.
