When was the Capitol built?
Construction of the U.S. Capitol began 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 restoration of the west front and terraces and the in-filling of courtyards, was completed in 1993. The most recent, and largest ever, addition to the Capitol, the Capitol Visitor Center, was completed in 2008. +Read More

How much did it cost to build the Capitol?
Up until 2003, the historical cost of building construction and property improvements was neither readily available nor accessible. A recent major effort was undertaken to research and determine the estimated historical cost. The Capitol is a unique structure, as it has been built in successive phases over the past two centuries. The estimated historical cost of the United States Capitol as of fiscal year 2003 is $133 million. This includes the original building (the Rotunda and the north and south wings) as it stood in 1824 ($2.4 million), the cast-iron dome added in 1866 ($1 million), and the extensions (which house the present House and Senate chambers as well as office and support spaces) completed in 1867 ($8.1 million). Numerous additions, renovations, and modernization efforts made throughout the years added another $122 million. Improvements to the Capitol Grounds have an estimated historical cost of $33.8 million as of fiscal year 2003; these include such items as landscaping, sidewalks, and security features.
Note that these numbers are given in historical dollars spent and have not been inflated to reflect current-day replacement value.

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.

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?
