The Capitol building houses the Senate, the House of Representatives, the Office of the Governor, the Office of the Lieutenant Governor, and the Department of the Treasury. The elected officials in the building work to make laws and administer state government.
The Capitol building was designed by Elijah E. Myers, and its construction lasted from 1886 through 1901. The Colorado Capitol was designed on an axis in the form of a Greek cross and resembles the basic design of the nation’s Capitol in Washington, D.C. The cost of the construction was about $3 million. The cost of replicating this building today is impossible to determine.
The exterior walls of the Capitol are constructed of granite quarried near Gunnison Colorado. The pink stone seen throughout the Capitol is rose onyx discovered near Beulah, Colorado. This coloration of onyx has never been found anywhere else in the world. The floors of the Capitol are constructed of yule marble from Marble, Colorado.
In 1908 Colorado gold miners made a gift of 200 ounces of gold to gild the dome. Rising 272 feet above the ground, the gleaming gold dome on the Colorado Capitol is a fitting tribute to the history of our state.
The Capitol is open Monday-Friday, 7:30-5:00. Free guided tours are available Monday-Friday at 10:00am, 11:00am, 12:00pm, and 1:00pm. Capitol tours are limited to 20 people on a first come, first served basis. All tours begin at the Visitor Information Desk, north side, first floor.
Capitol tours take about an hour and include a trip to the dome observation area. The dome is a 99 step climb above the 3rd floor and is accessible by stairs only. A closed-captioned video tour (near the third floor elevators) is available for visitors who are unable or do not wish to make the climb.
Self-guided tours of the dome are not permitted.
MASKS ARE OPTIONAL AT THE CAPITOL AND WHILE ON TOUR. SCHEDULED TOURS ARE SUBJECT TO CHANGE OR CANCELATION IN CONSIDERATION OF HEALTH AND SAFETY CONCERNS.
Two entrances are available for Capitol visitors. You may enter the building on the north side (Colfax and Sherman Avenues), up the stairs, or use the ADA accessible ground level entrance (14th and Sherman Avenues), under the stairs.
