Situated in the grounds of the Psychiatric Hospital of the City of Vienna, Kirche am Steinhof, built from 1904 to 1907, is the remarkable achievement of Otto Wagner. Kolo Moser chipped in with the mosaic windows, and the roof is topped by a copper-covered dome that earned the nickname Limoniberg (Lemon Mountain) from its original golden colour.
It’s a bold statement in an asylum that has other art-nouveau buildings, and it could only be pushed through by Wagner because the grounds were far from the public gaze.
