The Künstlerhaus in Vienna's 1st district has accommodated the Künstlerhaus Vereinigung since 1868. It is located in the Ringstrassenzone in between Akademiestraße, Bösendorferstraße and Musikvereinsplatz. The building was erected between 1865 and 1868 and has served as an exhibition space and an event venue ever since. In 2015, shares were split between two proprietors, with the Haselsteiner Familien-Privatstiftung as the majority shareholder and the Künstlerhaus Vereinigung, Gesellschaft bildender Künstlerinnen und Künstler Österreichs, the oldest existing artists' association in Austria, as the minority shareholder. In 1949 a cinema moved into the western wing of the building. As of 2013, this cinema is operated as Stadtkino im Künstlerhaus and is one of the screening venues for the annual Viennale film festival. Additionally, a theatre was established in the eastern wing in 1974, which was last operated by the brut until 2017. Between autumn 2016 and spring 2020, the Künstlerhaus faced a major renovation. During the reconstruction the former Altmann'sche Textilfabrik in Vienna-Margareten (Stolberggasse 26) served as its temporary accommodation. The newly refurbished Künstlerhaus was reopened on 6 March 2020. Today, the Künstlerhaus Vereinigung presents its exhibitions on the upper-floor of the building, while the Albertina Modern, which first opened its doors on 27 May 2020, shows/displays exhibitions on the ground- and underground-floor. Thus, the Künstlerhaus is now home to two independent cultural institutions.
