If you want to visit a different, even if not impacting place, you can go and either take a walk around or enter and visit the facilities. It's easily reachable by the Metro Line 14 (drop off at Bibliotheque Francois Miterrand Station). The view of the Seine river is magnificient. The 4 buildings standing at the 4 corners like 4 open books, with the woods garden in the middle makes it different, even if not as magificient as more classic buildings. The esplanade between the buildigns around and above the central garden is a place were people walk, jog, and the stairs around (especially on the north side) allow people to sit and relax while eating some snack. There are always some expositions Inside the complex, and there is a movies multi-theatre as well.
