Are there renovations going on now? What parts are closed?
The children's museum (lower ground), ground floor and first floor are open. Only half of the first floor is museum. Until they open the fourth floor don't bother.
3 floors are open, the time that I went, it was only restricted the area of the library. I recommend you the video of NYC (every 30 minutes)
I have not been there lately and am actually in Barcelona for the past week and not returning until the 3rd I go know that the building is quite old and periodically they renovate when they find the funds when they csn
Your best bet for a current and correct answer to these questions would be to ask the museum. You have reached a posting site on Trip Advisor, not the museum itself. Check the museum's website for contact information.
