Centre Pompidou, Paris

Commonly known as the Beaubourg, this distinctive building was commissioned in 1968 by the then President Georges Pompidou, and opened in 1977. Most Parisians were initially shocked by its unconventional 'inside out' architectural style: air conditioning, escalators, and lifts are all on the outside, giving the interior unparalleled freedom. Extensively refurbished in the late 1990s, the center is home to the Musée National d'Art Moderne and the Bibliothèque Publique d'Information (BPI) as well as temporary exhibitions, cinemas, and other attractions. Hours and admission prices vary for individual attractions.
