Living in an era of artistic and intellectual giants competing for attention, Otto Wagner was a celebrated architect, but his fame beyond Austria is not what it should be. But Wagner’s legacy of breathtaking designs lives on in buildings throughout Vienna, with his 1907 Kirche am Steinhof as perfect a little chapel as could be. Inaugurated by Archduke Franz Ferdinand, the art nouveau structure with the gold cupola literally shines from the western hills that lead into the Vienna Woods. With the chapel’s mosaics, visitors have a chance to discover the genius of Koloman Moser, a cofounder of the Wiener Werkstätte arts movement. His glass windows, along with gorgeous sculptural angels by Othmar Schimkowitz, have appeared on a commemorative 100-euro coin.
