The Lincoln Memorial is an American national monument built to honor the 16th President of the United States, Abraham Lincoln. It is located at the western end of the National Mall, across from the Washington Monument. The building is in the form of a Greek Doric temple and contains a large seated sculpture of Abraham Lincoln and inscriptions of two well-known speeches by Lincoln, "The Gettysburg Address" and his Second Inaugural Address. The Lincoln Memorial has been the site of many famous speeches, including Martin Luther King Jr.'s "I Have a Dream" speech, delivered on August 28, 1963. Abraham Lincoln is widely regarded as America's greatest president and the monument in his memory is an important public gathering place and national symbol.
The National Gallery of Art, located at the western level of the US Capitol, consists of two distinctly different buildings, one in the west, a neoclassical building with ancient Greek style, and one east in a geometric building of modernism. The two museums contain works of art from the Middle Ages to the present, unique architecture and rich and precious collections, giving the museum a unique style.
The White House is the official residence and workplace of the President of the United States. The building was designed by Irish-born architect James Hoban in a neoclassical style. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C. and has been the residence of every U.S. President since John Adams in 1800. Burnt by the British during the war of 1812, the White House has been remodeled and expanded several times over the years. While it is possible to tour parts of the White House interior, arrangements are difficult and must be made months in advance. As the symbol of US presidential power, the White House is an enormously important landmark.
The United States Capitol is the home of the United States Congress and the seat of the legislative branch of the US federal government. It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. The original building was completed in 1800 and subsequently expanded. Chambers for the bicameral legislature are located in each of the building's wing, the House of Representatives occupies the south wing and the Senate occupies the north wing. Like the principal buildings of the executive and judicial branches, the Capitol is built in a distinctive neoclassical style and has a white exterior. Tours of the interior are possible; however, these are best arranged by contacting individual members of Congress who consider tours part of their constituent services.
The Pentagon is the headquarters of the United States Department of Defense, the part of the US government charged with coordinating and supervising all agencies and functions concerned directly with national security and the United States Armed Forces. The Pentagon is located on the banks of the Potomac River in Arlington, Virginia. Dedicated in 1943, it is the world's largest office building. A well-known misconception held the most sensitive materials were housed in the building's central courtyard, resulting in this location being a prime target during the Cold War should hostilities have erupted between the United States and the Soviet Union.
