Welcome to the Colorado State Capitol

SOUTH, ADA Entrance under construction! This entrance is still open, but difficult to see. For ADA entrance, please go around Construction to the South East, ground level door. 

Booking field trips for the 24/25 school year now! 

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.
