4th Arrondissement Museums and Galleries
Place Georges-Pompidou, 4th
This postmodern building revolutionized the world of architecture—and turned the rarified concept of a museum into something that could be unintimidating and fun. Designed by Renzo Piano, Richard Rogers, and Gianfrancho Franchini, the Centre Pompidou is marked by an exterior lined with colorful tubes that hold the center's plumbing, electric, and circulation systems—inside, it's just as interactive. Home to a public library, a center for music and acoustic research, and the Musee National d’Art Moderne, since its inception in 1977 some of the most important modern art in the world has graced its walls, including pieces from Dali, Pollock, Warhol, and Picasso.
Maison Européenne de la Photographie
5 Rue de Fourcy, 4th
While the work of photographers like Helmut Newton might hypothetically seem too stark and modern for this rambling and elegant 18th century mansion, it's a combination that totally works: Beyond an impressive permanent collection, this museum always lands the exhibitions everyone is talking about, whether it's Shirin Neshat, Henri Cartier-Bresson, or Sebastião Salgado. Keep in mind that they're closed on Mondays and Tuesdays.
