This is the face of Vienna that is not to my taste.
State Hall of the Austrian National Library (Prunksaal).
It was designed by one of the two most popular architects of the Baroque days, Johann Bernhard Fischer von Erlach.
Unfortunately, Johann Bernhard died in 1723, the year that construction works started, and so the building was completed by his son Josef Emmanuel.
The Prunksaal is now incorporated into the Austrian National Library, but remains in its original shape. "Inside it is something like an orgasm of Baroque elements: lots and lots of marble, gold and stucco work blend together, are spiced up with frescos and wood decorations" (www.tourmycountry.com/austria/austriannationallibrary.htm).
On the square in front of it you can see a memorial of Emperor Joseph II, the big reformer of the enlightenment (the Emperor from the movie "Amadeus").
