Official account for the Architect of the Capitol — stewards of iconic buildings and grounds of Capitol Hill since 1793.
To serve Congress and the Supreme Court, preserve America's Capitol and inspire memorable experiences.
Since the laying of the Capitol cornerstone by George Washington in 1793, the Architect of the Capitol (AOC) has served the United States as builder and steward of many of the nation's most iconic and indelible landmark buildings. These include the U.S. Capitol, Capitol Visitor Center, Senate Office Buildings, House Office Buildings, Supreme Court, Library of Congress, U.S. Botanic Garden and Capitol Grounds.
Today, under the leadership of Stephen T. Ayers, Architect of the Capitol, the 2,600 employees of the AOC serve in diverse roles applying both modern techniques and historical tradecrafts in the care and preservation of the Capitol Campus.
The AOC works to: support the needs of nearly 30,000 occupants and millions of tourists who visit the campus annually; ensure the buildings and grounds meet modern standards for sustainability and accessibility; and preserve the historical legacy of the landmarks entrusted to the AOC’s care.
