Right in the middle of Hausmannian architecture in Paris, stands the Pompidou Centre. The Museum of Modern Art, if you will. It's sort of like a shoe-box on it's side, and the skeleton of the building is on the outside! It make for great space on the inside, though, because there are not very many inside columns or supports. Put up the wall for the art, and voila, there you have it. We saw an exhibit of Post-modern art all created by women; the feminist movement. Not my cup of tea, mind you, but very well done.
