Colorado State Capitol Building Rotunda in Denver, Colorado
Two types of marble grace the walls and floors of the impressive Colorado State Capitol in Denver. They are a rare Rose Onyx and Yule Marble. It took six years to install. When construction was done in 1894, the world’s supply of the Beulah Red Marble was depleted. The rotunda resembles a courtyard with the column-supported balconies and plenty of brass and stained glass. There is also a portrait of each U.S. president around the building.
