The most recent work of renowned Austrian sculptor and photographer Werner Feiersinger is an artistic intervention at the Belvedere 21, Austria&;s national museum for contemporary art, located in the former Austrian Pavilion for the 1958 Brussels World&;s Fair, which was transferred to Vienna in 1962. For this extensive sculptural work, Feiersinger took cues from the building&;s history and architectural details. As is characteristic of his work, the Belvedere 21 intervention combined the artist&;s deep and broad knowledge of design and architectural history with a laconic, minimalist formal vocabulary.             Werner Feiersinger.
