Few addresses inspired as much fear in the ghetto as ul. Kościelna 8/10. Known as the 'Red House,' it was commandeered by the Kripo (Criminal Police) as a headquarters to combat smuggling. In reality it was allowed to turn into a brutal interrogation centre, where those suspected of illegal activity would be tortured in the basements. Today the building is the property of the nearby Church of the Assumption of Our Blessed Mary, with only the plaque outside suggesting the sinister purpose the building once served.
