The Lentos Kunstmuseum, designed by Jörg Weber and Josef Hofer, is an oscillating three-story glass cube, 130 meters long by 30 meters wide, that fits seamlessly into the surrounding architectural landscape of the Danube River in Germany. It lies like a glass ship at anchor in Lintz, Germany, and provides 8,000 square meters of space for internationally renowned art from the classical modern period to the present. Below deck, as it were, is an underground library, museum shop, restaurant, café and bar. For their design of the Lentos, Weber and Hofer won the 2003 Architectural Achievement of the Year award from the province of Upper Austria and the 2003 Client's Prize from the Austrian government. This book celebrates the structural, technical and aesthetic details of their outstanding architectural project.
