The focal point of Vienna's inner city is St. Stephen's Square, where the Gothic spire of St. Stephen's Cathedral rises over the skyline.
Viennese law forbids the construction of any building taller than the cathedral. Tours of the cathedral include an ascent by elevator to the peak of the bell tower, where visitors may take in a commanding view of the city in all directions.
Another tour takes visitors down into the underground realm of the church, called the catacombs or crypts. Dukes, bishops, and common folk alike were buried in tombs under the cathedral during the Middle Ages.
