The Capitol

The US Capitol is one of the world's most impressive building's. It is the focal point of the government's Legislative Branch, the Capitol is the centerpiece of the Capitol Complex, which includes the six principal Congressional office buildings and three Library of Congress buildings constructed on Capitol Hill in the 19th and 20th centuries. In addition to its active use by Congress, the Capitol is a museum of American art and history. Each year, it is visited by an estimated 3-5 million people from around the world. A fine example of 19th-century neoclassical architecture, the Capitol combines function with aesthetics. Its designs derived from ancient Greece and Rome evoke the ideals that guided the nation's founders as they framed their new republic. As the building was expanded from its original design, harmony with the existing portions was carefully maintained. Today, the Capitol covers a ground area of 175,170 square feet, or about 4 acres, and has a floor area of approximately 16-1/2 acres. Its length, from north to south, is 751 feet 4 inches; its greatest width, including approaches, is 350 feet. Its height above the base line on the east front to the top of the Statue of Freedom is 288 feet; from the basement floor to the top of the dome is an ascent of 365 steps. The building contains approximately 540 rooms and has 658 windows (108 in the dome alone) and approximately 850 doorways.
