A new art location will be opening in the heart of Vienna in the spring of 2022. The museum for the famous collection of Heidi Goëss-Horten will be completed between the Albertina and the Opera House. The first museum publication is dedicated to the creation of this new exhibition venue, its architecture and construction history, positioning it within the context of the foundation of new museums. Heidi Horten’s art collection has been carefully built up since the early 1990s and presents its main focus on works of international modernism, Neo-Expressionism and American Pop-Art. The volume examines the previous historical buildings, their princely clients, the current redesign and the conversion of a former secular residential outbuilding into a contemporary art museum. In an interview with Heidi Goëss-Horten the collector and patron introduces herself and provides fascinating insights into a prestigious European private collection.
