There are 18 altars in the main part of the church, and more in the various chapels. The first focal point of any visitor is the distant High Altar , built over seven years from 1641 to 1647 as part of the first refurbishment of the cathedral in the baroque style. The altar was built by the Tobias Pock at the direction of Vienna's Bishop Philipp Friedrich Graf Breuner with marble from Poland, Styria and Tyrol. The High Altar represents the stoning of the church's patron St. Stephen. It is framed by figures of the patron saints of the surrounding areas — Saints Leopold, Florian, Sebastian and Rochus — and surmounted with a statue of St. Mary which draws the beholder's eye to a glimpse of heaven where Christ waits for Stephen (the first martyr) to ascend from below.
