The Arlington National Cemetery is the final resting place of the soldiers who gave their lives in service to the country. Two of America's former presidents, John F. Kennedy and William Howard Taft are buried here. The crew of the Challenger space shuttle, civil rights leader Medgar Evers and film star Audie Murphy are among the many honored here. The Tomb of the Unknown Soldiers, containing remains of unidentified soldiers from World Wars I, II, and the Korean War, are protected by the 3rd U.S. Infantry Regiment or the Old Guard 24 hours a day. The changing of the guard ceremony is a moving tribute to them.
Located at the west end of the National Mall, the Lincoln Memorial is one of the principal landmarks of Washington DC, its stately form overlooking the Reflecting Pool, a gleaming stretch of water that lays sprawled before its base. Daniel Chester French's 19-foot (5.7-meter) statue of Lincoln, seated and deep in thought, watches over the nation he helped create, alongside the carved text of the Gettysburg Address, providing a glimpse into a weighty period of American history. The memorial itself draws inspiration from the Greek architectural style, its 36 Doric columns representative of the number of states in the union at the time of Lincoln's death. Surrounded by greenery, on the banks of the Potomac River, the Lincoln Memorial makes for a soul-stirring, picturesque sight; a fitting ode to one of the nation's most revered Presidents.
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.
The symbol of the city of Washington DC, this 555-foot (169-meter) marble obelisk on the National Mall honors the nation's first president, George Washington. The cornerstone of the Washington Monument was laid in 1848, but construction was not completed until 1884. About one-third of the way up the obelisk is a visible change in the marble, evidence of the onset of the Civil War. Construction was halted during the war, and when the builders returned to the same quarry to complete the project afterward, enough time had passed to cause a significant change in the color. An emblem of the United States and an icon of the nation, the Washington Monument is a moving sight, its elegant form mirrored in the Reflecting Pool of the Lincoln Monument nearby.
Part of the original design for the federal city, this massive park stretches from the US Capitol to the Lincoln Memorial and around the Tidal Basin to the Jefferson Memorial. It has played host to many momentous, world-changing events throughout history including the 1963 March on Washington, the Million Man March and several presidential inaugurations. Today, the National Mall serves as a place for reflection, a memorial to American heroes, a symbol of freedom and a forum for the exercise of democracy. The Smithsonian museums, the Vietnam Memorial, the Reflecting Pool and the iconic Washington Monument are a few of the most well-known of the National Mall's many iconic sites. Certainly, any visit to Washington DC should start with a tour of the United States National Mall, aptly named "America's front yard."
Best known for its vast collection of azaleas, (a popular porch-flower), this 446-acre (180-hectare) garden park has much else to offer.

The National Bonsai Collection, a gift from Japan, is a fascinating exhibit of tiny trees. Other notable sections are the aquatic garden (filled with lotuses of many varieties) and the National Herb Garden.
