St. Stephen's Cathedral
Vienna, AT
You can not think of Vienna without thinking of the St. Stephen Cathedral. This notorious religious building is well recognizable for its four towers, the tallest of which - south tower- measures 136.44 meters. 343 steps bring visitors to the tower room, from which there is a breathtaking view across Vienna. Besides the beautiful altars and side chapels, the cathedral is also home to a vast treasury, which includes relics decorated with gold and precious stones, liturgical books and vestments.
