Rated Tourist Attractions in Washington

An underground passage with historical exhibits leads from the Capitol Building to one of Washington's little-known places to visit, the Library of Congress. It's the world's largest library, modeled on the Opera House in Paris. You can visit portions on your own, but free tours disclose even more of its beautiful interior.

Near the Smithsonian museums, the United States Holocaust Memorial Museum documents, studies, and interprets the history of the Holocaust with the dual purpose of memorializing the victims and helping the world to confront hatred and prevent genocide.

Housed in two separate buildings connected by a tunnel, the National Gallery of Art is one of the world's premier art museums and one of the most popular in the U.S. Based on the sizable collection of financier and later Treasury Secretary Andrew Mellon, its large and diverse collection includes masterpieces of European and American paintings, sculpture, and decorative arts.

The National Air and Space Museum is one of the world's most popular museums, with a collection of history-making air and spacecraft that includes the original 1903 Wright Brothers Flyer and Charles Lindbergh's Spirit of St. Louis, the first plane to fly solo across the Atlantic Ocean.

The 555-foot white shaft of the Washington Monument is a familiar icon of the National Mall, and a beautiful sight, especially when mirrored in the long Reflecting Pool at its foot. Construction of the obelisk to honor the nation's first president did not proceed smoothly. The plan was approved by Congress in 1783, but ground wasn't broken until 1848.

The neighborhood from 27th to 37th Streets, between Rock Creek Park and K Street NW, is the city's oldest, with origins in the early 1700s, before Washington itself. Georgetown University, the nation's oldest Roman Catholic and Jesuit College, is located here.

The English-style, Neo-Gothic National Cathedral, one of the world's largest cathedrals, took 83 years to build, from 1907 to 1990. It follows the Gothic building style and techniques, with flying buttresses and solid masonry construction of Indiana limestone. Throughout the cathedral are artistic details to see, from its stained-glass windows to the hand-embroidered kneelers that commemorate war heroes and historic events.

On a hillside overlooking the city from across the Potomac River, Arlington National Cemetery is filled with memorials to American history and the men and women who were part of it. Its best-known landmarks are the Tomb of the Unknown Soldier, President John F. Kennedy's gravesite, and the U.S. Marine Corps War Memorial depicting the raising of the flag on Iwo Jima in World War II. The Welcome Center has maps, information (including the locations of specific graves), exhibits telling the story of Arlington National Cemetery and its monuments.

The place for 007 wannabes, the museum covers the techniques, technology, history, and contemporary role of espionage. Many of the exhibits are interactive, and throughout the building are actual examples of real espionage equipment (including a poison dart umbrella designed by the KGB), from declassified hardware and captured equipment to movie props used in the James Bond series.

The National Archives holds permanent records of the U.S. Congress, the U.S. Supreme Court, District of Columbia courts, and some federal agencies, as well as pre-World War I military service records for U.S. Army and Confederate veterans, and pre-1940 vessel and station logbooks for the U.S. Navy.

The National Zoo is another part of the Smithsonian, where nearly 2,000 different animals, birds, and reptiles live in habitats replicating as closely as possible their natural environments. Of the several hundred species represented here, about a quarter are endangered. This is one of the world's best zoos, not only for the quality of the visitor experience, but for its leadership in areas of animal care and sustainability.
