United States Capitol

United States Capitol. The United States Capitol is the seat of the United States Congress, the legislative branch of the federal government. Located atop Capitol Hill at the eastern end of the National Mall in Washington, D.C., it is an iconic symbol of American democracy and a major tourist attraction. The building houses the Senate and House of Representatives chambers, along with numerous historic art collections and architectural features.

History

The history of the Capitol begins with the Residence Act of 1790, which established a permanent national capital on the Potomac River. President George Washington selected the site, and the cornerstone was laid in a ceremony on September 18, 1793. The original design by architect William Thornton was selected in a competition promoted by Thomas Jefferson. The building was first occupied by Congress in 1800, though construction was incomplete. It was burned by British forces during the War of 1812 in the Burning of Washington, leading to a major reconstruction overseen by architects Benjamin Henry Latrobe and later Charles Bulfinch. The Capitol was significantly expanded in the mid-19th century under the direction of Thomas U. Walter to accommodate a growing nation, adding the massive new cast-iron dome and extending the wings for the Senate and House of Representatives. The modern Capitol Visitor Center, opened in 2008, is the most recent major addition.

Architecture and design

The architecture of the Capitol is a premier example of American neoclassicism, intended to evoke the ideals of ancient Greek democracy and the Roman Republic. Its most dominant feature is the massive cast-iron dome, designed by Thomas U. Walter and constructed during the American Civil War, crowned by the Statue of Freedom. The interior of the dome features the famous fresco, *The Apotheosis of Washington*, painted by Constantino Brumidi. The building's interior is adorned with extensive artwork, including the National Statuary Hall Collection and numerous historical paintings and frescoes. The original central section, or Rotunda, connects the two wings and serves as a ceremonial space for events such as presidential inaugurations and the lying in state of notable figures like Abraham Lincoln and John F. Kennedy.

Functions and operations

As the working seat of Congress, the Capitol's primary function is to facilitate the legislative process. It contains the chambers of the Senate and the House of Representatives, where members debate and vote on legislation. The building also houses the offices of congressional leaders, including the Speaker of the House and the Vice President in their role as President of the Senate. Important ceremonial events held here include the counting of Electoral College votes during a joint session and the annual State of the Union address delivered by the President of the United States. The Architect of the Capitol is responsible for the maintenance, operation, and preservation of the building and its grounds.

Grounds and surrounding area

The Capitol is set within a sprawling 274-acre park known as the United States Capitol Grounds, designed primarily by famed landscape architect Frederick Law Olmsted. The grounds feature extensive walkways, monuments, and gardens, including the Summerhouse, a brick grotto built in 1879. The area is framed by important institutions and buildings, such as the Library of Congress, the Supreme Court building, and the United States Botanic Garden. To the west, the National Mall stretches toward the Washington Monument and the Lincoln Memorial, forming the central axis of the capital's monumental core. The immediate neighborhood of Capitol Hill is a residential and commercial district that houses many members of Congress, staff, and journalists.

Security and incidents

Security at the Capitol has evolved significantly, particularly following major incidents. It is protected by the United States Capitol Police, a federal law enforcement agency. A tragic early attack was the 1890 shooting of a former U.S. Representative by a disgruntled journalist. A more violent incident occurred in 1954 when four Puerto Rican nationalists opened fire from the House gallery, wounding five members of Congress. The most severe breach in modern history was the attack on January 6, 2021, when a mob stormed the building in an attempt to disrupt the certification of the 2020 presidential election. This event led to a major review of security protocols. Other security measures include permanent perimeter fencing installed after the September 11 attacks and a robust network of surveillance and access controls managed by the United States Capitol Police Board.
