Frequently Asked Questions

The questions answered below are among the most frequently asked about the Capitol. You may also wish to read more detailed information about the Capitol's history and its works of art.


What is the function of the Capitol?
The Capitol houses the meeting chambers of the Senate (in the north wing) and the House of Representatives (in the south wing), the two bodies that compose the legislative branch of the American government. It also includes the offices of the congressional leadership, and it is used for ceremonies of national importance such as presidential inaugurations and the lying in state of eminent persons. The Capitol is also a museum of American art and history and is visited by millions of people every year. An overview of the building and its function and photographs of the Capitol's east front (54k .jpg) and west front (54k .jpg) are also available.
Who designed the Capitol?
The original design was drawn by Dr. William Thornton, but there have been ten Architects of the Capitol. Detailed information about each Architect's contributions to the building's design and construction is available, as is a summary of the responsibilities of the Architect of the Capitol.
When was the Capitol built?
The Capitol was begun in 1793 and has been "completed" several times. The original building was finished in 1826. The growth of the Congress compelled its expansion in the middle of the 19th century; the extensions and new dome were finished in 1868. An addition to the east front in 1958-1962 added more rooms to the Capitol. The most recent work, the restoration of the west front and terraces and the in-filling of courtyards, was completed in 1993. Detailed information about the Capitol's construction is also available.
When did the Congress first meet in the Capitol?
November 17, 1800.
What is the Capitol made of?
The original building, completed in 1826, was made of brick clad in sandstone. The north and south wings and connecting corridors added in the mid 19th century and the replica of the east front constructed in the 20th century are made of brick clad in marble; the dome is made of 8,909,200 pounds of cast iron. Detailed information about the building's construction and the dome are also available.
What are the dimensions of the Capitol?
Its length, from north to south, is 751 feet 4 inches; its greatest width is 350 feet. Its height above the base line on the east front to the top of the Statue of Freedom is 288 feet.
How much did it cost to build the Capitol?
Because the Capitol has been built over almost 200 years, it is impossible to calculate a meaningful total construction cost.
What is the name of the statue on top of the dome?
It is the Statue of Freedom, an allegorical female figure. Detailed information about the statue and a photograph (21k .jpg) are also available.
Why does the Statue of Freedom face east, away from the mall?
The Capitol's east front was planned, and still serves, as its principal entrance (being the only front on level ground), and the statue thus faces those who arrive from this direction.
Where and what is the Capitol Rotunda?
The Rotunda is a circular room in the center of the building beneath the Capitol dome. It is 96 feet in diameter and rises 180 feet from the floor to the canopy, with a volume of approximately 1.3 million square feet. Detailed information about the Rotunda is also available.
How many statues are there in the National Statuary Hall Collection?
Ninety-six. Each state may contribute two statues; all but four states (Nevada, New Mexico, North Dakota, and Wyoming) have done so.
How many women are represented in the National Statuary Hall Collection?
Six: Mother Joseph (Washington), Esther Hobart Morris (Wyoming), Jeanette Rankin (Montana), Dr. Florence Sabin (Colorado), Maria Sanford (Minnesota), and Frances E. Willard (Illinois).
What is the largest statue in the Statuary Hall Collection?
The statue of King Kamehameha I, donated by the state of Hawaii. The bronze statue is 9'-10" tall and stands on a 3'-6" granite base; their combined wieght is approximately 15,000 pounds.
Is there a "whispering gallery" in the Capitol?
The half-dome shape of National Statuary Hall produces an acoustical effect whereby, in some spots, a speaker many yards away may be heard more clearly than one closer at hand. The modern-day echoes occur in different locations from those in the 19th century, when the floor and ceiling of the hall were different.
Is there any symbolic significance to the numbers of columns and steps in various locations in the Capitol?
No. The numbers of columns and steps were determined for aesthetic and practical, rather than symbolic, reasons.
Was the Capitol used as a prison during the Civil War?
No. However, a building known as the "old brick Capitol" was. The old brick Capitol was built for the use of the Congress after the Capitol was burned by invading British troops during the War of 1812; it stood on part of the site now occupied by the Supreme Court Building. Congress occupied the old brick Capitol between 1815 and 1819, while the Capitol was being rebuilt. The old brick Capitol was then used for various purposes; during the Civil War it served as a prison for the confinement of Confederate captives and of suspected collaborators. Following the Civil War the building was converted to residences. It was removed before the October 1932 laying of the cornerstone of the Supreme Court building.
Is anyone buried in the Capitol?
No. A tomb area was built for the remains of George Washington beneath the Crypt, but his will specified that he wished to be buried at his home at Mount Vernon, and his descendents honored this wish.
Which is taller, the Capitol or the Washington Monument?
The Washington Monument, standing 555 feet tall, is 267 feet taller than the Capitol. Because the base of the Washington Monument is 30 feet above sea level, and that of the Capitol is 88 feet above sea level, the top of the Washington Monument is 209 feet higher than the top of the Capitol.
