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 famous pieces of art and other temporary exhibitions.
