Radical in 1977, radical in 2017: Renzo Piano and Richard Rogers's Pompidou Center in Paris, with the inside on the outside, color coded by function and organized around the idea of movement. Of course on the day we visited we couldn't move inside from outside due to a workers' strike (En Grève!) so we have no idea if with the inside on the outside the outside is likewise on the inside. Though if the inside were truly on the outside these exterior photos would show the Cy Twombly exhibition our traveling companion was hoping to see since of course the inside of a museum isn't just filled with the electrical, plumbing and ventilation systems but also the art. False advertising!
