The Capitol is the seat of the US Congress
The United States Capitol, often called the Capitol or the Capitol Building, is the seat of the US Congress, the legislative branch of the federal government. It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. The Capitol has been built, burnt, rebuilt, extended and restored since its construction began in 1793. Today, it covers 1.5 million square feet, has over 600 rooms, and miles of corridors. It is crowned by a magnificent white dome that has become an iconic symbol of the American people and government.
The Capitol was designed by Pierre L'Enfant and selected by President George Washington. Construction began shortly after its selection in 1793. The building combines function with aesthetics, with its design inspired by ancient Greece and Rome. The central sections of the present building were completed in 1800 but were partly destroyed in 1814 during the Burning of Washington. It was fully restored within five years and enlarged in the 1850s by extending the wings to accommodate the chambers for the bicameral legislature.
The second floor holds the Chambers of the House of Representatives and the Senate, as well as the offices of the congressional leadership. This floor also contains three major public areas. In the centre under the dome is the Rotunda, a circular ceremonial space that also serves as a gallery of paintings and sculptures depicting significant people and events in the nation's history. The semicircular chamber south of the Rotunda served as the Hall of the House until 1857 and now houses part of the Capitol's collection of statues donated by the states. The Old Senate Chamber, used by the Senate until 1859, has been restored to its mid-19th-century appearance.
The Capitol is a highly secure building. The United States Capitol Police have installed checkpoints to inspect vehicles and screen visitors and their belongings. The Capitol is a popular tourist destination, attracting an estimated 3-5 million visitors from around the world each year.

The United States Capitol Building, located in Washington, D.C., is an iconic example of 19th-century neoclassical architecture. Its design was chosen by President George Washington in 1793, and construction commenced shortly after. Since then, the Capitol has undergone several transformations, including being built, burnt, rebuilt, extended, and restored.

The building has been expanded from its original design, carefully maintaining harmony with the existing portions. Today, it covers approximately 1.5 million square feet, with over 600 rooms and miles of corridors.
The Capitol has experienced several periods of construction and restoration. In 1803, Benjamin Henry Latrobe was tasked with completing the north and south wings, which suffered from structural issues. Latrobe demolished, redesigned, and rebuilt the interiors, designing the Supreme Court and Senate chambers. Charles Bulfinch, Latrobe's successor, continued the restoration of the north and south wings and constructed the central section, which was topped with a copper-covered wooden dome.
In the 1850s, the building underwent another significant expansion. The wings were extended to accommodate the bicameral legislature, with the House of Representatives in the south wing and the Senate in the north wing. This expansion included the addition of three major public areas: the Rotunda, the National Statuary Hall, and the Old Senate Chamber.
The Capitol has also undergone more recent renovations and extensions. In 1904, the East Front was rebuilt, and in 1958, a major expansion began with the extension of the East Portico. The dome was restored in 1960, and a connecting extension in 1962 repurposed an outside wall as an inside wall. Today, the Capitol stands as a monument to its builders and the American people, housing both a museum of American art and history and the active chambers of Congress.
