Vienna, like most historic cities has most of its main architectural highlights within walking distance of each other. These are located in the Innere Stadt (Inner City).
During a meeting there I had the opportunity to stroll through the city centre which is bounded by the Ringstrasse (Ring Road). I guess they keep names fairly literal in Vienna.
St Stephan's Catherdral (Stephansdom) is a good starting point for a stroll around. The thing you notice straight away is the roof, which is covered in colourful tiles forming striking geometric patterns.
The seat of the Archbishop of Vienna, the church's origins go back to 1147 though what you see now was largely built in the 14th and 15th centuries. Definitely worth a look and good starting point for a general wander around what is one of the most stunning and impressive cities I have visited.
