The interior design of the 19th/20th-century drawing room is inspired by the history of the Loewenfeld family. Starting in the second half of the 19th century, Chrzanów, a private city, became the property of a company of Wrocław merchants, including Emanuel Loewenfeld. He soon became its only owner. He was married to Róża Ascher and had four sons: Wilhelm, Adolf, Henryk, and Brunon. All of them had made a mark on the city's history by linking their lives with Chrzanów. Róża and Henryk had a particularly positive impact. They funded numerous projects, including charitable ones, as well as the main avenue of the city, named after Henryk to this day. Loewenfelds' chapel-mausoleum designed by the Lviv architect Teodor Talowski stands in the parish cemetery. Until the outbreak of the Second World War, the family lived in the current Chrzanów Museum building - the former manor storehouse. It was also the gathering place for the "Żaby" choir. The secondary school teacher, Adolf Loewenfeld, was a member of the choir and its president. A plaque on a wall of the Museum building commemorates this fact.
