The BNF (Bibliothèque Nationale de France) or differently named "Bibliothèque Francois Mitterrand". This group of buildings have one of the most beautiful architecture I've ever seen. A must see place in Paris.
BNF, Paris, France.
I'm sorry for the watermark on the image but unfortunately a lot of people and companies on the web are using it without giving me any credit. So if anyone wants to use it, please email me.
