Between the Halles district and the Marais in Paris is the Centre Pompidou, an art and cultural center. In contrast to the historic buildings of the quarter, the Centre Pompidou features shocking modern architecture, sometimes described as an "inside out" design because the architectural details of staircases and elevators appear on the exterior. The main attraction of the Centre Pompidou is the National Museum of Modern Art, which displays an extensive collection of contemporary art, beginning with the Fauves (Derain, Dufy, Matisse, and Bonnard) continuing with Cubism (Picasso, Braque, and Leger), then Expressionism, Constructivism (Klee and Mondrian), Dadaism and Surrealism (Dali, Ernst, Magritte, and Masson), Abstract Expressionism (de Stael, Hartung, Poliakoff, Estere, and Dubuffet), New Realism, and Pop Art (Warhol, Oldenburg). The sculpture collection is also noteworthy.
