The Stephansdom is one of the symbols of Vienna. This Gothic Cathedral stands tall in the perfect centre since the 14th century. Back in the day, more than 10 000 people were buried under this church. Now, a part of the catacombs is open to visitors who are interested in this kind of thing. So you could go down into the depths of the city and see its past. Or, alternatively, rise high above it for a different experience.
