National Gallery of Art Washington, DC

The National Gallery houses an extensive collection of European and American art in two spectacular buildings. In the grand, neoclassical West Building, Rembrandt, Rubens and Gainsborough are well-represented. The permanent collection includes works from the 13th to 20th Centuries including a section devoted to Impressionism. An underground concourse with a cafeteria, an excellent gift shop and a walled-in waterfall takes you to the East Building. Designed by I.M. Pei, this triangular building is a key city landmark and home to 20th-century art works and temporary exhibitions.
