United States Capitol Complex, Government complex in Washington, D.C., United States
The United States Capitol Complex is a group of government buildings in Washington, D.C., spreading across roughly 100 acres and encompassing several key structures. It includes the main Capitol building, offices for senators and representatives, the Library of Congress, and the Supreme Court.
Construction of the Capitol began in 1793 when President George Washington laid the cornerstone, marking the start of one of America's most important building projects. The dome was completed in 1866, symbolizing the nation's restoration and unity following the Civil War.
The Capitol Rotunda displays significant American artworks including historical paintings and sculptures representing different periods of national development. Visitors can also explore the ornately decorated Brumidi Corridors with their intricate frescoes and detailed decorative elements.
The Capitol Visitor Center offers guided tours of the complex, exhibitions, and services for more than three million visitors each year. It helps to check security requirements before visiting, as thorough screening procedures are conducted at all entrances.
The dome is made of cast iron and weighs around 4 million kilograms, making it one of the heaviest dome roofs in the world. This structure was an engineering feat at the time, as it was built entirely from metal to support the immense weight.
