18th century Prior to establishing the nation's capital,
Washington, D.C., the
United States Congress and its predecessors met at
Independence Hall and
Congress Hall in
Philadelphia;
Federal Hall in
New York City, and five additional locations:
York, Pennsylvania;
Lancaster, Pennsylvania; the
Maryland State House in
Annapolis, Maryland;
Nassau Hall in
Princeton, New Jersey; and
Trenton, New Jersey. In September 1774, the
First Continental Congress brought together delegates from the
colonies in Philadelphia, followed by the
Second Continental Congress, which met from May 1775 to March 1781. After adopting the
Articles of Confederation in York, Pennsylvania, the
Congress of the Confederation was formed and convened in Philadelphia from March 1781 until June 1783, when a mob of angry soldiers converged upon Independence Hall, demanding payment for their service during the
American Revolutionary War. Congress requested that
John Dickinson, the
Governor of Pennsylvania, call up the
militia to defend Congress from attacks by the protesters. In what became known as the
Pennsylvania Mutiny of 1783, Dickinson sympathized with the protesters and refused to remove them from Philadelphia. As a result, Congress was forced to flee to
Princeton, New Jersey, on June 21, 1783, and met in
Annapolis, Maryland, and
Trenton, New Jersey, before ending up in New York City. The U.S. Congress was established upon
ratification of the
U.S. Constitution and formally began on March 4, 1789. New York City remained home to Congress until July 1790, when the
Residence Act was passed to pave the way for a permanent capital. The decision of where to locate the capital was contentious, but
Alexander Hamilton helped broker a compromise in which the federal government would take on war debt incurred during the American Revolutionary War, in exchange for support from
northern states for locating the capital along the
Potomac River. As part of the legislation, Philadelphia was chosen as a temporary capital for ten years (until December 1800), until the nation's capital, Washington, D.C., would be ready.
Pierre L'Enfant was charged with creating
the city plan for the new capital city and the major public buildings. The Congress House would be built on Jenkins Hill, now known as
Capitol Hill, which L'Enfant described as a "pedestal awaiting a monument." L'Enfant connected Congress House with the President's House via
Pennsylvania Avenue with a width set at 160 feet, identical to the narrowest points of the
Champs-Élysées in Paris. Westwards was a garden-lined "grand avenue" containing a public walk (later known as the
National Mall) that would travel for about along the east–west line. The term "Capitol" (from Latin
Capitolium) originally denoted the
Capitoline Hill in Rome and the
Temple of Jupiter that stood on its summit. The Roman Capitol was sometimes misconceived of as a meeting place for senators, and this led the term to be applied to legislative buildings; the first such building was the
Williamsburg Capitol in
Virginia.
Thomas Jefferson had sat here as a member of the
House of Burgesses, and it was he who applied the name "Capitol" to what on L'Enfant's plan had been called the "Congress House". "Capitol" has since become a general term for government buildings, especially in the United States. It is often confused with "capital"; the former, however, denotes a building or complex of buildings, while the latter denotes a city. L'Enfant secured the lease of
quarries at
Wigginton Island and along
Aquia Creek in
Virginia for use in the
foundations and outer walls of the Capitol in November 1791. Surveying was under way soon after the Jefferson conference plan for the Capitol was accepted. In early 1792, after
Pierre L'Enfant was dismissed from the federal city project, Jefferson proposed a design competition to solicit designs for the Capitol and the "President's House", and set a four-month deadline. The prize for the competition was $500 and a lot in the Federal City. At least ten individuals submitted designs for the Capitol; however the drawings were regarded as crude and amateurish, reflecting the level of architectural skill present in the United States at the time. The most promising of the submissions was by
Stephen Hallet, a trained French architect who was a draftsman to Pierre L'Enfant on the city plan. However, Hallet's designs were overly fancy, with too much French influence, and were deemed too costly. However, the design did incorporate the concept for a "great circular room and dome" which had originated with L'Enfant.
John Trumbull was given a tour of "Jenkins Hill" by L'Enfant himself and confirmed this in his autobiography years later. On January 31, 1793, a late entry by amateur architect
William Thornton was submitted, and was met with praise for its "Grandeur, Simplicity, and Beauty" by Washington, along with praise from Jefferson. Thornton was inspired by the
east front of the Louvre, as well as the
Paris Pantheon for the center portion of the design. Thornton's design was officially approved in a letter dated April 5, 1793, from Washington, and Thornton served as the first
architect of the Capitol (and later first superintendent of the
U.S. Patent and Trademark Office). In an effort to console Hallet, the commissioners appointed him to review Thornton's plans, develop cost estimates, and serve as superintendent of construction. Hallet proceeded to pick apart and make drastic changes to Thornton's design, which he saw as costly to build and problematic. In July 1793, Jefferson convened a five-member commission, bringing Hallet and Thornton together, along with
James Hoban (winning architect of the "President's Palace") to address problems with and revise Thornton's plan. Hallet suggested changes to the floor plan, which could be fitted within the exterior design by Thornton. The revised plan was accepted, except that Secretary Jefferson and President Washington insisted on an open
recess in the center of the East front, which was part of Thornton's original plan. The original design by Thornton was later significantly altered by
Benjamin Henry Latrobe, and later
Charles Bulfinch. The
current cast-iron dome, the House's new southern extension, and the
Senate's new northern wing were designed by
Thomas Ustick Walter and
August Schoenborn in the 1850s, and were completed under the supervision of
Edward Clark. Construction proceeded with Hallet working under supervision of
James Hoban, who was also busy working on construction of the "President's House" (also later known as the "Executive Mansion"). Despite the wishes of Jefferson and the President, Hallet went ahead anyway and modified Thornton's design for the East Front and created a square central court that projected from the center, with flanking wings which would house the legislative bodies. Hallet was dismissed by Secretary Jefferson on November 15, 1794.
George Hadfield was hired on October 15, 1795, as Superintendent of Construction, but resigned three years later in May 1798, because of his dissatisfaction with Thornton's plan and quality of work done thus far.
Slave labor was extensively used in the construction of the Capitol, as Washington frequently experienced shortages of free white craftsmen. The slaves, mostly
from Maryland and
Virginia, were hired out by their owners to the federal government, which paid the enslavers and provided housing, rations and limited medical care to the enslaved laborers. This practice kept labor costs low, prevented the government from having to directly purchase slaves and provided between $55 and $65 annually for individual enslavers. The Polish writer
Julian Ursyn Niemcewicz, who visited Washington in the late 1790s, wrote about visiting the Capitol worksite:
19th century of the U.S. Capitol after the
burning of Washington by the
British Army during the
War of 1812 of the east side of the Capitol in 1846, by
John Plumbe, showing Bulfinch's dome The Senate (north) wing was completed in 1800. The Senate and House shared quarters in the north wing until a temporary wooden pavilion was erected on the future site of the House wing which served for a few years for the Representatives to meet in, until the
House of Representatives (south) wing was finally completed in 1811, with a covered wooden temporary walkway connecting the two wings with the Congressional chambers where the future center section with rotunda and dome would eventually be. However, the House of Representatives moved early into their House wing in 1807. Though the Senate wing building was incomplete, the Capitol held its
first session of the U.S. Congress with both chambers in session on November 17, 1800. The National Legislature was moved to
Washington prematurely, at the urging of President
John Adams, in hopes of securing enough
Southern votes in the
Electoral College to be re-elected for a second term as president. In March 1803,
James Madison appointed
Benjamin Henry Latrobe to the position of "Surveyor of Public Buildings", with the principal responsibility of completing construction of the Capitol's south and north wings. Work on the north wing began in November 1806. Although occupied for only six years, it had suffered from falling plaster, rotting floors and a leaking roof. Instead of repairing it, Latrobe demolished, redesigned and rebuilt the interiors within the existing brick and sandstone walls. Notably, Latrobe designed the Supreme Court and Senate chambers. The former was a particular architectural achievement; the size and structure of its vaulted, semi-circular ceiling was then unprecedented in the United States. For several decades, beginning when the federal government moved to Washington in the fall of 1800, the Capitol building was used for Sunday religious services as well as for governmental functions. The first services were conducted in the "hall" of the House in the north wing of the building. In 1801 the House moved to temporary quarters in the south wing, called the "Oven", which it vacated in 1804, returning to the north wing for three years. Then, from 1807 to 1857, they were held in the then-House Chamber (now called
Statuary Hall). When held in the House chamber, the Speaker's podium was used as the preacher's pulpit. According to the
U.S. Library of Congress exhibit
Religion and the Founding of the American Republic: Not long after the completion of both wings, the Capitol was
partially burned by the
British on August 24, 1814, during the
War of 1812. After the fires, Latrobe was rehired as Architect of the Capitol to oversee restoration works.
George Bomford and
Joseph Gardner Swift, both military engineers, were called upon to help rebuild the Capitol. Reconstruction began in 1815 and included redesigned chambers for both Senate and House wings (now sides), which were completed by 1819. During the reconstruction, Congress met in the
Old Brick Capitol, a temporary structure financed by local investors. Construction continued through to 1826, with the addition of the center section with front steps and columned portico and an interior
Rotunda rising above the first low dome of the Capitol. Latrobe is principally connected with the original construction and many innovative interior features; his successor Bulfinch also played a major role, such as design of the first low dome covered in copper. By 1850, it became clear that the Capitol could not accommodate the growing number of legislators arriving from newly admitted states. A new design competition was held, and President
Millard Fillmore appointed Philadelphia architect
Thomas U. Walter to carry out the expansion. Two new wings were added: a new chamber for the House of Representatives on the south side, and a new chamber for the Senate on the north. When the Capitol was expanded in the 1850s, some of the construction labor was carried out by
slaves "who cut the logs, laid the stones and baked the bricks". The original plan was to use workers brought in from Europe. However, there was a poor response to recruitment efforts; African Americans, some free and some enslaved, along with Scottish stonemasons, comprised most of the workforce.
Capitol dome in 1861, before the partially complete Capitol dome The 1850 expansion more than doubled the length of the United States Capitol; it dwarfed the original, timber-framed, copper-sheeted, low dome of 1818, designed by
Charles Bulfinch which was no longer in proportion with the increased size of the building. In 1855, the decision was made to tear it down and replace it with the "
wedding-cake style" cast-iron dome that stands today. Also designed by
Thomas U. Walter, the new dome would stand three times the height of the original dome and in diameter, yet had to be supported on the existing masonry piers. Like
Mansart's dome at
Les Invalides in Paris (which he had visited in 1838), Walter's dome is double, with a large
oculus in the inner dome, through which is seen
The Apotheosis of Washington painted on a shell suspended from the supporting ribs, which also support the visible exterior structure and the
tholos that supports the
Statue of Freedom, a colossal statue that was raised to the top of the dome in 1863. The statue invokes the goddesses
Minerva or
Athena. The
cast iron for the dome weighs . The dome's
cast iron frame was supplied and constructed by the iron foundry
Janes, Fowler, Kirtland & Co. The thirty-six Corinthian columns that surround the base of the dome were provided by the Baltimore ironworks of
Poole & Hunt. at the
National Arboretum in 2008 When the Capitol's new dome was finally completed, its massive visual weight, in turn, overpowered the proportions of the columns of the East
Portico, built in 1828.
20th century In 1904, the East Front of the Capitol building was rebuilt, following a design of the architects
Carrère and Hastings, who designed the
Russell Senate and
Cannon House office buildings earlier that year. In 1958, the next major expansion to the Capitol started, with a extension of the East Portico. In 1960, two years into the project, the dome underwent a restoration. As this body was long defunct, responsibility for the material passed to the House and Senate office building commissions. These commissions then arranged for the
National Park Service to store the debris at the back of a NPS maintenance yard in
Rock Creek Park. With the permission of the
speaker of the House, the United States Capitol Historical Society has periodically mined the blocks for sandstone since 1975. The stone removed is used to make commemorative bookends and paperweights, which are still sold to support the Capitol Historical Society. By 1982, more than $20,000 (nearly $60,000
adjusted) had been raised through such sales. The building was ranked No. 6 in a 2007 survey conducted for the
American Institute of Architects' "
America's Favorite Architecture" list. The Capitol draws heavily from other notable buildings, especially churches and landmarks in Europe, including the dome of
St. Peter's Basilica in the
Vatican and
St. Paul's Cathedral in London. On the roofs of the Senate and House Chambers are flagpoles that fly the
U.S. flag when either is in session. On September 18, 1993, to commemorate the Capitol's bicentennial, the Masonic ritual cornerstone laying with George Washington was reenacted. U.S. senator
Strom Thurmond was one of the Freemason politicians who took part in the ceremony.
21st century '' On June 20, 2000, ground was broken for the
Capitol Visitor Center, which opened on December 2, 2008. From 2001 through 2008, the East Front of the Capitol (site of most
presidential inaugurations until
Ronald Reagan began a new tradition in 1981) was the site of construction for this massive underground complex, designed to facilitate a more orderly entrance for visitors to the Capitol. Prior to the center being built, visitors to the Capitol had to line up in the basement of the Cannon House Office Building or the Russell Senate Office Building. The new underground facility provides a grand entrance hall, a visitors theater, room for exhibits, and dining and restroom facilities, in addition to space for building necessities such as a
service tunnel. A large-scale Capitol dome restoration project, the first extensive such work since 1959–1960, began in 2014, with completion scheduled before the 2017 presidential inauguration. As of 2012, $20 million in work around the skirt of the dome had been completed, but other deterioration, including at least 1,300 cracks in the brittle iron that have led to rusting and seepage inside, needed to be addressed. Before the August 2012 recess, the
Senate Appropriations Committee voted to spend $61 million to repair the exterior of the dome. The House wanted to spend less on government operations, but in late 2013, it was announced that renovations would take place over two years, starting in spring 2014. In 2014, extensive scaffolding was erected, enclosing and obscuring the dome. All exterior scaffolding was removed by mid-September 2016. With the increased use of technologies such as the Internet, a bid tendering process was approved in 2002 for a contract to install the multidirectional radio communication network for
Wi-Fi and mobile-phone within the Capitol Building and annexes, followed by the new Capitol Visitor Center. The winning bidder was an
Israeli company called Foxcom which has since changed its name and been acquired by
Corning Incorporated. ==Interior==
