The result of an open architectural competition held in 1983, work did not commence under 1987 with the museum finally opening on 6th June 1991. The architect chosen was Hans Hollein, who won the Pritzker Architecture Prize in 1985. The long drawn out project is sited on an awkward triangular site. The Museum offers exhibition spaces that allow for a multitude of possible uses. These spaces combine both daylight and artificial lighting systems, creating optimal lighting for the various requirements of the art objects and the provision of external views. In spite of its somewhat bizarre shape, the gallery has a bright, spacious air. Some critics have claimed that the dazzling architecture is more interesting than the exhibits.
