09 - Tenement houses on Próżna Street
Before the war, mainly Jewish people lived here, and the street had commercial character. Zalman Nożyk, the founder of the nearby synagogue, lived in the tenement house at number 9. The famous industrialist Majer Wolanowski lived in the house at number 14. Initially, he ran a hardware store here. With time, he founded a factory producing wire, nails and roofing cardboard on Gęsia Street. With time, he expanded the scope of production for the needs of the railway. It is worth mentioning that Próżna is one of the few streets in Warsaw that survived the destruction of the ghetto.
