Formerly known as the Zwanzigerhaus, the building was originally the Austrian Pavilion at the 1958 Brussels World Fair. Built, dismantled and rebuilt by Karl Schwanzer, it is one of the most important Austrian architectural monuments of the ’50s. It has now been brought right up to date with a renovation and name change. Open to the public again since late 2011, it showcases Austrian art from the 20th and 21st century.
