The Kirchner Museum houses the world's largest collection of work by Ernst Ludwig Kirchner, the German Expressionist painter who spent the last 20 years of his life in Davos. Kirchner's Alpine paintings — savage, angular, vibrating with colour — are a complete departure from his urban Berlin work and show the mountains as something wild and overwhelming rather than picturesque.
The purpose-built museum, designed by Gigon/Guyer and opened in 1992, is itself a significant piece of architecture — four glass and concrete cubes that manage to feel both austere and luminous. The permanent collection covers all periods of Kirchner's output; temporary exhibitions bring in Expressionist and modern art from around Europe. It's one of the more rewarding small museums in Switzerland and well worth two hours.
