Today it plays host to contemporary exhibitions of art, culture, science and technology in its main hall 'La Nef'.. The building is also home to the science museum, the 'Palais de la Decouverte'.
Even if your not into art exhibitions the building itself, which actually contains more steel than the Eiffel Tower, is worth a visit even if just to view it internally.
