The Kirche am Steinhof on a hilltop in the western edge of Vienna is Otto Wagner's Jugendstil masterpiece and one of Europe's great early-modern churches. Completed in 1907 for the patients of the Steinhof psychiatric hospital, it was the first church in the world built with full attention to hygiene, light, and the needs of mental-health patients.
The copper dome was originally fully gilded; the white marble facade is studded with bronze rivets. Inside, the spare interior glows with stained glass by Koloman Moser. The church is now part of a hospital but is open to visitors. Bus 48A from Burggasse.
