The National Mall is a large, open park area in the center of the city. Located in the center of the Mall are the Washington Monument and the Jefferson Pier. Also located on the mall are the Lincoln Memorial, the National World War II Memorial at the east end of the Reflecting Pool, the Korean War Veterans Memorial, and the Vietnam Veterans Memorial. The National Archives houses thousands of documents important to American history including the Declaration of Independence, the United States Constitution, and the Bill of Rights.
Located directly south of the mall, the Tidal Basin features rows of Japanese cherry blossom trees that were presented as gifts from the nation of Japan. The Franklin Delano Roosevelt Memorial, Jefferson Memorial, and the District of Columbia War Memorial are located around the Tidal Basin.
The Smithsonian Institution is an educational foundation chartered by Congress in 1846 that maintains most of the nation's official museums and galleries in Washington, D.C. The U.S. government partially funds the Smithsonian, thus making its collections open to the public free of charge. The most visited of the Smithsonian museums in 2009 was the National Museum of Natural History located on the National Mall. Other Smithsonian Institution museums and galleries located on the mall are: the National Air and Space Museum; the National Museum of African Art; the National Museum of American History; the National Museum of the American Indian; the Sackler and Freer galleries, which both focus on Asian art and culture; the Hirshhorn Museum and Sculpture Garden; the Arts and Industries Building; the S. Dillon Ripley Center; and the Smithsonian Institution Building (also known as "The Castle"), which serves as the institution's headquarters.
The Smithsonian American Art Museum (formerly known as the National Museum of American Art) and the National Portrait Gallery are located in the same building, the Donald W. Reynolds Center, near Washington's Chinatown. The Reynolds Center is also known as the Old Patent Office Building. The Renwick Gallery is officially part of the Smithsonian American Art Museum but is located in a separate building near the White House. Other Smithsonian museums and galleries include: the Anacostia Community Museum in Southeast Washington; the National Postal Museum near Union Station; and the National Zoo in Woodley Park.

The National Gallery of Art is located on the National Mall near the Capitol, but is not a part of the Smithsonian Institution. It is instead wholly owned by the U.S. government; thus admission to the gallery is free. The gallery's West Building features the nation's collection of American and European art through the 19th century. The East Building, designed by architect I. M. Pei, features works of modern art. The Smithsonian American Art Museum and the National Portrait Gallery are often confused with the National Gallery of Art when they are in fact entirely separate institutions. The National Building Museum occupies the former Pension Building located near Judiciary Square, and was chartered by Congress as a private institution to host exhibits on architecture, urban planning, and design.
There are many private art museums in the District of Columbia, which house major collections and exhibits open to the public such as: the National Museum of Women in the Arts; the Corcoran Gallery of Art, the largest private museum in Washington; and The Phillips Collection in Dupont Circle, the first museum of modern art in the United States. Other private museums in Washington include the Newseum, the International Spy Museum, the National Geographic Society Museum, and the Marian Koshland Science Museum. The United States Holocaust Memorial Museum located near the National Mall maintains exhibits, documentation, and artifacts related to The Holocaust
