Welcome to the Colorado State Capitol

The Colorado State Capitol field trip program is fully booked for the remainder of the 23/24 school year. You are able to book field trips up to one year in advance and doing so is strongly recommended. Self guided field trips are allowed, but will not include a trip to the Dome Observation area. Please email for self guiding materials or with questions. 


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.

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.
