National Gallery of Art

The National Gallery of Art is an art museum in Washington, D.C., United States, located on the National Mall, between 3rd and 9th Streets, at Constitution Avenue NW. Open to the public and free of charge, the museum was privately established in 1937 for the American people by a joint resolution of the United States Congress. Andrew W. Mellon donated a substantial art collection and funds for construction.

The core collection includes major works of art donated by Paul Mellon, Ailsa Mellon Bruce, Lessing J. Rosenwald, Samuel Henry Kress, Rush Harrison Kress, Peter Arrell Browne Widener, Joseph E. Widener, and Chester Dale. The Gallery's collection of paintings, drawings, prints, photographs, sculpture, medals, and decorative arts traces the development of Western art from the Middle Ages to the present and includes the largest mobile created by Alexander Calder.

The Gallery's campus includes the original neoclassical West Building designed by John Russell Pope, which is linked underground to the modernist East Building, designed by I. M. Pei, and is next to the 6.1-acre (25,000 m2) Sculpture Garden. The Gallery often presents temporary special exhibitions spanning the world and the history of art. It is one of the largest museums in North America.
