Dům Gustava Mahlera, Museum and cultural monument in Jihlava, Czech Republic.

Dům Gustava Mahlera stands at Znojemská 4 in Jihlava, in a house where Gustav Mahler grew up from 1860. The building, protected as a cultural monument since 1958, holds the exhibition Gustav Mahler and Jihlava, with a stylized reconstruction of Bernard Mahler's tavern in the basement and works by Jihlava-born artist Thea Weltner on the ground floor.

The Mahler family moved to Jihlava in 1860, and Gustav grew up in this house on what was then Brtnická Street. His father Bernard opened a distillery and taproom here in 1861; Gustav lived in the house until 1875 and sold it after his parents' deaths in 1889. A memorial plaque by sculptor Milan Knobloch was unveiled on the facade on 19 June 1960, and the house has been a protected cultural monument since 1958.

The house reflects the diversity that shaped Jihlava during Mahler's time, with Czech, German, and Jewish communities living side by side and influencing the city's cultural life. Visitors can trace these connections through the exhibitions and see how such differences touched the young composer.

The house stands at Znojemská 4, with the exhibition on the upper floors reached by stairs. The ground floor holds the information and sales point, and the top floor houses the research room and the offices of the Spolek Dům Gustava Mahlera association. The building has been in the city's direct management since July 2008.

In the basement, a stylized reconstruction of Bernard Mahler's tavern and distillery recalls the family business that operated in the house's courtyard wing. The top floor holds a research room and the seat of the Gustav Mahler House Association.
