The United States Capitol, often known as the Capitol Building, is the meeting location of the United States Congress and the seat of the United States federal government's legislative branch. It is located on Capitol Hill in Washington, D.C., near the eastern extremity of the National Mall. Though it is no longer located in the federal district's physical center, the Capitol serves as the starting point for the district's transportation system. The current capitol was built from 1792 to 1800 by Henry Hobson and John G. Skinner; it replaced an earlier capitol destroyed by fire in 1814. The current building was extensively remodeled between 1816 and 1824 in the Greek Revival style by Benjamin Henry Latrobe. In 2005, Congress authorized $140 million in repairs and renovations to the Capitol. The United States Capitol is a large complex consisting of a number of buildings arranged on a rectangular plan around a central lawn. The largest single structure within the grounds is the U.S. Capitol Building itself, which measures 756 feet (230 m) long and 340 feet (105 m) wide. It is composed of three parts: the Senate Wing, the House Wing, and the Supreme Court Wing. Adjacent to the Capitol Building are two other major structures: the Congressional Office Buildings, which contain the offices of members of Congress and their staffs; and the Hart Senate Office Building, which houses the offices of senators. Farther east on Capitol Hill is the Library of Congress, one of the world's largest libraries.
