One of the smallest museums in Poznań and quite tricky to visit. Not only do you have to call ahead to inform the museum of your visit (within the specified opening hours), you then need to find the dang place – go through the courtyard, ring the doorbell, then climb to the second floor. The series of rooms here are filled with rusty pots, scales, vials, and cast iron mortars from the 18-20th centuries. While in the past you'd find yourself wandering around in ignorance, the museum now offers small guides in English, German, and French. One room has been designed to mimic a 19th century pharmacy - complete with a box for morphine - while another includes over 1,200 rare medical books, a stuffed alligator, and an inmate's uniform recovered from Mathausen.
