Otto Wagner Church or Steinhof Church, (Kirche am Steinhof) - also called the Church of St. Leopold, built between 1903 and 1907 by the 63-year-old architect Otto Wagner.
It is considered one of the most important Art Nouveau churches in the world.

The copper-covered dome of this prime example of Viennese Art Nouveau architecture is visible from quite a distance, as the church stands high on the crest of the hill.
On the two bell towers enthrone the bronze figures made by the sculptor Richard Luksch (1872-1936): Saint Leopold, protection patron of Vienna and Lower Austria, on the west tower, and Saint Severin, protection patron of Linz, on the east tower.
