Find Stephansdom at Stephjansplatz 3 in central Vienna. Enter on the west through the oddly named Giant's Gate, which is flanked on either side by the Towers of the Heathen. The southeastern tower, or Stuffl, is 449-feet tall. The view from up there is superb, but you have to pay to go up. The never-finished north tower or Adlerturn is home to the 21.3-ton Pummerin bell, which was made of the bronze of cannons captured by Austrian armies from the Turks. There's an elevator up to the bell tower, but admission is charged there as well.
Proceed counter-clockwise and along the south side of the church you'll find the Chapel of St. Eligius and the Pötscher Madonna, which shed tears when the Austrians beat the Turks in the Battle of Zenta in 1697.
Move along, passing the Singer's Door, Canon's Sacristy, Lower Sacristy, the South Transept and Chapel of St. Katherine and the red marble tomb of the Emperor Frederick III. At the east end of the church is the main altar, with the Archbishop's Throne and High Altar behind it.
Continue around to the north side of the church past the Winter Sacristy, the gilded and painted Wiener Neustädter Altarpiece, the North Transept and Chapel of St. Barbara and the Gothic Pulpit, which features the carved heads of Saints Jerome, Augustine, Gregory the Great and Ambrose. Next up is the Bishop's Door and the Chapel of the Cross, which contains the tomb of Austrian hero Prince Eugene of Savoy.
Take the stairs in the North Transept down to the Crypts and Catacombs. The highlight here is the urns containing the entrails of members of the Hapsburg dynasty. Apparently their bodies are buried at one church, their hearts in another and everything else winds up here.
