The gleaming Lentos Kunstmuseum stops you dead in your tracks. Defined by razor-sharp lines, this glass-and-steel landmark was designed by Zurich architects Weber & Hofer, who decided to leave a large gap in the base of its rectangular shape. The gallery showcases a world-class collection of contemporary art, including works by Warhol, Schiele, Klimt and Kokoschka, which is complemented by rotating exhibitions.
