Bonjour, an FYI for those planning to visit the Pompidou Center over the next 4-5 weeks. Level 5 is closed until October 21. I was disappointed yesterday to find that only Level 4 was open, plus the special exhibit floor. Level 4 is contemporary art, Level 5 is 20th Century modern art, for example, Picasso. You can still go to the top level for the excellent view of Paris, however.
Speaking of Picasso, I can tell you that the Picasso Museum is definitely closed. I walked by the other day, and the builidng is a shell, I believe the sign says the estimated opening is April 2014. From the looks of things, though, I'd be surprised if it is open by then.
