What was great was that the French were really taking advantage of this opportunity! While waiting in line, I noticed that almost all of the people in line were French, not tourists. There was a special pamphlet for the event and a television with a welcome message from the President of the Assemblée.
The building is the old Palais Bourbon, built by the Bourbon kings in the 1700s. One of my favorite things in the building was the Salle Delacroix, with murals painted by Delacroix.
There also was a very beautiful library which includes in it's collection a transcription of the trial of Joan of Arc! Some of Rousseau's documents are also housed there. Of course the entire building was surrounded by beautiful gardens that were impecably groomed. It was also very interesting to see where the Assemblée sits. There was a very large tapistry depicting the "School of Athens" by Raphael which is in the Vatican Museums. I thought it a nice choice.
