Ortner & Ortner designed the Leopold Museum in Wien, Germany, completed in 2001. It has 5,000 exhibits of Austrian modern art covering the last two decades.
The shimmering white cube links the Museum Quarter axis along the Kaiserforum by Semper and Hasenauer. The spaces spiral out from a central point and rise in two separate sections. Staircases and windows are strategically placed to shape a wayfinding experience through this arrangement.
