Map - Kunsthaus Zürich (Kunsthaus)

The Kunsthaus Zürich is in terms of area the biggest art museum of Switzerland and houses one of the most important art collections in Switzerland, assembled over time by the local art association called Zürcher Kunstgesellschaft. The collection spans from the Middle Ages to contemporary art, with an emphasis on Swiss art.

The old museum part was drawn-up by architects Karl Moser and Robert Curjel and opened in 1910. Particularly notable are the several preserved Moser interiors in the original section of the museum, decorated in masterful Neo-Grec version of Secession style. The bas-reliefs on the facade are by Moser's longtime collaborator Oskar Kiefer. The original museum building was extended in 1925, 1958 and 1976.

A $230 million extension by London-based David Chipperfield was opened in 2020. Half of the extension's budget came from the city and canton of Zurich, with the other half provided by private donors. Chipperfield's design is a massive rectangular sandstone-covered building. The extension will add 5040 sqft of galleries, increasing display space by 78%. The Kunsthaus will become the largest Swiss art museum, overtaking the Kunstmuseum Basel in the available space but not the collection. The two upper floors will be for art, with facilities at ground level and a basement link under the street to the original museum across the street in Heimplatz.

Lydia Escher (1858–1891), being a prominent Zürich patron of the arts, was honored by the Gesellschaft zu Fraumünster association on the occasion of her 150th anniversary by a commemorative plaque, located at the front of the building. The place was baptized on 20 August 2008 by the city of Zürich as Lydia Welti-Escher Hof.
