The birthplace of the single greatest achievement of Western Civilization: Mozart’s Don Giovanni, in a beautiful photo by Jean-François Chaubard.
The Prague State Opera House (formerly, the New German Theatre) is a gorgeous neo-recoco edifice, built in the early 1880’s. Unfortunately, it’s surrounded by soviet-era architectural atrocities on the sides & a very busy thouroughfare in front – so it’s hard to take a good picture. This one is the best I’ve found.
This is the most beautiful picture I could find of this magnificent building. It was taken by Miroslav Petrasko. He is a wonderfully talented and skilled photographer. On his blog, you can see many great photos of Prague and other central European cities, and get lots of excellent advice for taking your own photos.
