Each Architect of the Capitol helped shape the iconic buildings and grounds we know today.
The Madison Building is an unusual combination of a national shrine contained in a working building serving both as the Library's third major structure and as this nation's official memorial to President James Madison.
Earlier efforts to provide space for the Senate had included the construction of the Russell Building and the Dirksen Building. By 1967, the Senate began to experience a strain on its existing office facilities and initiated the process that led to the creation of the Hart Building.
Completed in 1992, the Thurgood Marshall building cost $101 million, providing more than 600,000 square feet of rentable space within its overall million-square-foot interior.
The U.S. Capitol Visitor Center is the newest addition to the historic Capitol Complex. At nearly 580,000 square feet, the Visitor Center is the largest project in the Capitol's more than two-century history and is approximately three-quarters the size of the Capitol itself.
