Inside the Stephansdom (St. Stephen's Cathedral) there are many altars, like these 3 side altars.
In the back the St. Joseph altar, the middle is St. Januarius altar and up front (right) a for me unknown altar.
Stephansdom (St. Stephen's Cathedral) is the mother church of the Roman Catholic Archdiocese of Vienna (Austria).
The current Romanesque and Gothic form of the cathedral, seen today in the Stephansplatz (St. Stephen's Square), was largely initiated by
Duke Rudolf IV (1339–1365) and stands on the ruins of two earlier churches, the first a parish church consecrated in 1147. The most important religious building in Austria's capital, St. Stephen's Cathedral has borne witness to many important events in that nation's history and has,
with its multi-coloured tile roof, become one of the city's most recognizable symbols.
