CAPITOL BUILDINGS AND GROUNDS
UNITED STATES CAPITOL
Overview of the Building and Its Function
The United States Capitol is among the most architecturally
impressive and symbolically important buildings in the world. It has
housed the meeting chambers of the Senate and the House of
Representatives for almost two centuries. Begun in 1793, the Capitol has
been built, burnt, rebuilt, extended, and restored; today, it stands as
a monument not only to its builders but also to the American people and
their government.
As the focal point of the government's Legislative Branch, the
Capitol is the centerpiece of the Capitol Complex, which includes the
six principal Congressional office buildings and three Library of
Congress buildings constructed on Capitol Hill in the 19th and 20th
centuries.
In addition to its active use by Congress, the Capitol is a museum
of American art and history. Each year, it is visited by an estimated
seven to ten million people from around the world.
A fine example of 19th-century neoclassical architecture, the
Capitol combines function with aesthetics. Its designs derived from
ancient Greece and Rome evoke the ideals that guided the Nation's
founders as they framed their new republic. As the building was expanded
from its original design, harmony with the existing portions was
carefully maintained.
Today, the Capitol covers a ground area of 175,170 square feet, or
about 4 acres, and has a floor area of approximately 16\1/2\ acres. Its
length, from north to south, is 751 feet 4 inches; its greatest width,
including approaches, is 350 feet. Its height above the base line on the
east front to the top of the Statue of Freedom is 287 feet 5\1/2\
inches; from the basement floor to the top of the dome is an ascent of
365 steps. The building contains approximately 540 rooms and has 658
windows (108 in the dome alone) and approximately 850 doorways.
The building is divided into five levels. The first, or ground,
floor is occupied chiefly by committee rooms and the spaces allocated to
various congressional officers. The areas accessible to visitors on this
level include the Hall of Columns, the Brumidi Corridor, the restored
Old Supreme Court Chamber, and the Crypt beneath the rotunda, where
historical exhibits are presented.
The second floor holds the Chambers of the House of Representatives
(in the south wing) and the Senate (in the north wing) as well as the
offices of the congressional leadership. This floor also contains three
major public areas. In the center under the dome is the rotunda, a
circular ceremonial space that also serves as a gallery of paintings and
sculpture depicting significant people and events in the Nation's
history. The rotunda is 96 feet in diameter and rises 180 feet 3 inches
to the canopy. The semicircular chamber south of the rotunda served as
the Hall of the House until 1857; now designated National Statuary Hall,
it houses part of the Capitol's collection of statues donated by the
States in commemoration of notable citizens. The Old Senate Chamber
northeast of the rotunda, which was used by the Senate until 1859, has
been returned to its mid-19th-century appearance.
The third floor allows access to the galleries from which visitors
to the Capitol may watch the proceedings of the House and the Senate
when Congress is in session. The rest of this floor is occupied by
offices, committee rooms, and press galleries.
The fourth floor and the basement/terrace level of the Capitol are
occupied by offices, machinery rooms, workshops, and other support
areas.
Location of the Capitol
The Capitol is located at the eastern end of the Mall on a plateau
88 feet above the level of the Potomac River, commanding a westward view
across the Capitol Reflecting Pool to the Washington Monument 1.4 miles
away and the Lincoln Memorial 2.2 miles away. The geographic location of
the head of the Statue of Freedom that surmounts the Capitol dome is
described by the National Geodetic Survey as latitude
38 deg.53'23.31098'' north and longitude 77 deg.00'32.62262'' west.
Before 1791, the Federal Government had no permanent site. The early
Congresses met in eight different cities: Philadelphia, Baltimore,
Lancaster, York, Princeton, Annapolis, Trenton, and New York City. The
subject of a permanent capital for the government of the United
[[Page 559]]
States was first raised by Congress in 1783; it was ultimately addressed
in Article I, Section 8 of the Constitution (1787), which gave the
Congress legislative authority over ``such District (not exceeding ten
Miles square) as may, by Cession of Particular States, and the
Acceptance of Congress, become the Seat of the Government of the United
States. . . .''
In 1788, the state of Maryland ceded to Congress ``any district in
this State, not exceeding ten miles square,'' and in 1789 the State of
Virginia ceded an equivalent amount of land. In accordance with the
``Residence Act'' passed by Congress in 1790, President Washington in
1791 selected the area that is now the District of Columbia from the
land ceded by Maryland (private landowners whose property fell within
this area were compensated by a payment of <brit-pound>25 per acre);
that ceded by Virginia was not used for the capital and was returned to
Virginia in 1846. Also under the provisions of that Act, he selected
three Commissioners to survey the site and oversee the design and
construction of the capital city and its government buildings. The
Commissioners, in turn, selected the French engineer Pierre Charles
L'Enfant to plan the new city of Washington. L'Enfant's plan, which was
influenced by the gardens at Versailles, arranged the city's streets and
avenues in a grid overlaid with baroque diagonals; the result is a
functional and aesthetic whole in which government buildings are
balanced against public lawns, gardens, squares, and paths. The Capitol
itself was located at the elevated east end of the Mall, on the brow of
what was then called Jenkins' Hill. The site was, in L'Enfant's words,
``a pedestal waiting for a monument.''
Selection of a Plan
L'Enfant was expected to design the Capitol and to supervise its
construction. However, he refused to produce any drawings for the
building, claiming that he carried the design ``in his head''; this fact
and his refusal to consider himself subject to the Commissioners'
authority led to his dismissal in 1792. In March of that year the
Commissioners announced a competition, suggested by Secretary of State
Thomas Jefferson, that would award $500 and a city lot to whoever
produced ``the most approved plan'' for the Capitol by mid-July. None of
the 17 plans submitted, however, was wholly satisfactory. In October, a
letter arrived from Dr. William Thornton, a Scottish-trained physician
living in Tortola, British West Indies, requesting an opportunity to
present a plan even though the competition had closed. The Commissioners
granted this request.
Thornton's plan depicted a building composed of three sections. The
central section, which was topped by a low dome, was to be flanked on
the north and south by two rectangular wings (one for the Senate and one
for the House of Representatives). President Washington commended the
plan for its ``grandeur, simplicity and convenience,'' and on April 5,
1793, it was accepted by the Commissioners; Washington gave his formal
approval on July 25.
Brief Construction History
1793-1829
The cornerstone was laid by President Washington in the building's
southeast corner on September 18, 1793, with Masonic ceremonies. Work
progressed under the direction of three architects in succession.
Stephen H. Hallet (an entrant in the earlier competition) and George
Hadfield were eventually dismissed by the Commissioners because of
inappropriate design changes that they tried to impose; James Hoban, the
architect of the White House, saw the first phase of the project through
to completion.
Construction was a laborious and time-consuming process: the
sandstone used for the building had to be ferried on boats from the
quarries at Aquia, Virginia; workers had to be induced to leave their
homes to come to the relative wilderness of Capitol Hill; and funding
was inadequate. By August 1796 the Commissioners were forced to focus
the entire work effort on the building's north wing so that it at least
could be ready for government occupancy as scheduled. Even so, some
third-floor rooms were still unfinished when the Congress, the Supreme
Court, the Library of Congress, and the courts of the District of
Columbia occupied the Capitol in late 1800.
In 1803, Congress allocated funds to resume construction. A year
earlier, the office of the Commissioners had been abolished and replaced
by a Superintendent of the City of Washington. To oversee the renewed
construction effort, Benjamin Henry Latrobe was appointed architect. The
first professional architect and engineer to work in America, Latrobe
modified Thornton's plan for the south wing to include space for offices
and committee rooms; he also introduced alterations to simplify the
construction work. Latrobe began work by removing a squat, oval,
temporary building known as ``the Oven,'' which had been erected in 1801
as a meeting place for the House of Representatives. By 1807
construction on the south wing was sufficiently advanced that the House
was able to occupy its new legislative chamber, and the wing was
completed in 1811.
[[Page 560]]
In 1808, as work on the south wing progressed, Latrobe began the
rebuilding of the north wing, which had fallen into disrepair. Rather
than simply repair the wing, he redesigned the interior of the building
to increase its usefulness and durability; among his changes was the
addition of a chamber for the Supreme Court. By 1811, he had completed
the eastern half of this wing, but funding was being increasingly
diverted to preparations for a second war with Great Britain. By 1813,
Latrobe had no further work in Washington and so he departed, leaving
the north and south wings of the Capitol connected only by a temporary
wooden passageway.
The War of 1812 left the Capitol, in Latrobe's later words, ``a most
magnificent ruin'': on August 24, 1814, British troops set fire to the
building, and only a sudden rainstorm prevented its complete
destruction. Immediately after the fire, Congress met for one session in
Blodget's Hotel, which was at Seventh and E Streets, NW. From 1815 to
1819, Congress occupied a building erected for it on First Street, NE,
on part of the site now occupied by the Supreme Court Building. This
building later came to be known as the Old Brick Capitol.
Latrobe returned to Washington in 1815, when he was rehired to
restore the Capitol. In addition to making repairs, he took advantage of
this opportunity to make further changes in the building's interior
design (for example, an enlargement of the Senate Chamber) and introduce
new materials (for example, marble discovered along the upper Potomac).
However, he came under increasing pressure because of construction
delays (most of which were beyond his control) and cost overruns;
finally, he resigned his post in November 1817.
On January 8, 1818, Charles Bulfinch, a prominent Boston architect,
was appointed Latrobe's successor. Continuing the restoration of the
north and south wings, he was able to make the chambers for the Supreme
Court, the House, and the Senate ready for use by 1819. Bulfinch also
redesigned and supervised the construction of the Capitol's central
section. The copper-covered wooden dome that topped this section was
made higher than Bulfinch considered appropriate to the building's size
(at the direction of President James Monroe and Secretary of State John
Quincy Adams). After completing the last part of the building in 1826,
Bulfinch spent the next few years on the Capitol's decoration and
landscaping. In 1829, his work was done and his position with the
government was terminated. In the 20 years following Bulfinch's tenure,
the Capitol was entrusted to the care of the Commissioner of Public
Buildings.
1830-1868
The Capitol was by this point already an impressive structure. At
ground level, its length was 351 feet 7\1/2\ inches and its width was
282 feet 10\1/2\ inches. Up to the year 1827--records from later years
being incomplete--the project cost was $2,432,851.34. Improvements to
the building continued in the years to come (running water in 1832, gas
lighting in the 1840s), but by 1850 its size could no longer accommodate
the increasing numbers of senators and representatives from newly
admitted States. The Senate therefore voted to hold another competition,
offering a prize of $500 for the best plan to extend the Capitol.
Several suitable plans were submitted, some proposing an eastward
extension of the building and others proposing the addition of large
north and south wings. However, Congress was unable to decide between
these two approaches, and the prize money was divided among five
architects. Thus, the tasks of selecting a plan and appointing an
architect fell to President Millard Fillmore.
Fillmore's choice was Thomas U. Walter, a Philadelphia architect who
had entered the competition. On July 4, 1851, in a ceremony whose
principal oration was delivered by Secretary of State Daniel Webster,
the President laid the cornerstone for the northeast corner of the House
wing in accordance with Walter's plans. Over the next 14 years, Walter
supervised the construction of the extensions, ensuring their
compatibility with the architectural style of the existing building.
However, because the Aquia Creek sandstone used earlier had already
deteriorated noticeably, he chose to use marble for the exterior. For
the veneer, Walter selected marble quarried at Lee, MA, and for the
columns he used marble from Cockeysville, MD.
Walter faced several significant challenges during the course of
construction. Chief among these was the steady imposition by the
government of additional tasks without additional pay. Aside from his
work on the Capitol extensions and dome, Walter designed the wings of
the Patent Office building, extensions to the Treasury and Post Office
buildings, and the Marine barracks in Pensacola and Brooklyn. When the
Library of Congress in the Capitol's west central section was gutted by
a fire in 1851, Walter was commissioned to restore it. He also
encountered obstacles in his work on the Capitol extensions. His
location of the legislative chambers was changed in 1853 at the
direction of President Franklin Pierce, based on the suggestions of the
newly appointed supervising engineer, Captain Montgomery C. Meigs. In
general, however, the project progressed rapidly: the House of
Representatives was able to meet in its new chamber on December 16,
1857, and the Senate first met
[[Page 561]]
in its present chamber on January 4, 1859. The old House chamber was
later designated National Statuary Hall. In 1861 most construction was
suspended because of the Civil War, and the Capitol was used briefly as
a military barracks, hospital, and bakery. In 1862 work on the entire
building was resumed.
As the new wings were constructed, more than doubling the length of
the Capitol, it became apparent that the dome erected by Bulfinch no
longer suited the building's proportions. In 1855 Congress voted for its
replacement based on Walter's design for a new, fireproof cast-iron
dome. The old dome was removed in 1856, and 5,000,000 pounds of new
masonry was placed on the existing rotunda walls. Iron used in the dome
construction had an aggregate weight of 8,909,200 pounds and was lifted
into place by steam-powered derricks.
In 1859, Thomas Crawford's plaster model for the Statue of Freedom,
designed for the top of the dome, arrived from the sculptor's studio in
Rome. With a height of 19 feet 6 inches, the statue was almost 3 feet
taller than specified, and Walter was compelled to make revisions to his
design for the dome. When cast in bronze by Clark Mills at his foundry
on the outskirts of Washington, it weighed 14,985 pounds. The statue was
lifted into place atop the dome in 1863, its final section being
installed on December 2 to the accompaniment of gun salutes from the
forts around the city.
The work on the dome and the extensions was completed under the
direction of Edward Clark, who had served as Walter's assistant and was
appointed Architect of the Capitol in 1865 after Walter's resignation.
In 1866, the Italian-born artist Constantino Brumidi finished the canopy
fresco, a monumental painting entitled The Apotheosis of George
Washington. The Capitol extensions were completed in 1868.
1869-1902
Clark continued to hold the post of Architect of the Capitol until
his death in 1902. During his tenure, the Capitol underwent considerable
modernization. Steam heat was gradually installed in the Old Capitol. In
1874 the first elevator was installed, and in the 1880s electric
lighting began to replace gas lights.
Between 1884 and 1891, the marble terraces on the north, west, and
south sides of the Capitol were constructed. As part of the grounds plan
devised by landscape architect Frederick Law Olmsted, these terraces not
only added over 100 rooms to the Capitol but also provided a broader,
more substantial visual base for the building.
