Kirche am Steinhof, also called the Church of St. Leopold, is the Roman Catholic oratory of the Steinhof Psychiatric Hospital in Vienna, Austria. The building designed by Otto Wagner is considered one of the most important Art Nouveau churches in the World.
The church, situated 310 metres (1,020 ft) above sea level, dominates and forms part of the Steinhof Psychiatric Hospital; previous official title was Niederösterreichische Landes-Heil- und Pflegeanstalt für Nerven- und Geisteskranke 'Am Steinhof' (Lower Austrian State Healing and Care Institution for the Neurologically and Mentally Sick, 'Am Steinhof'). It is located on a hillside (the Baumgartnerhöhe) below the Galitzinberg in the 14th Vienna district, Penzing. It has a separate status as part of the surrounding hospital and does not form part of the Archdiocese of Vienna.
