The Colorado State Capitol Building is located at 200 East Colfax Avenue in Denver, Colorado. The building was designed by Elijah E. Myers to be intentionally reminiscent of the United States Capitol. The architectural style is Corinthian and has a Greek Cross floor plan. Construction on the Capitol began in 1890 and was completed in 1908. The building was constructed using the finest native Colorado materials available including a rare Colorado Rose Onyx. The distinctive dome consists of a plate of pure gold first added in 1908 commemorating the Colorado Gold Rush.

Allen Architectural Metals was responsible for the re-creation of the elaborate cast bronze stair systems located in the four quadrants of the building. These cast bronze components were replications of the original designs for the buildings. Each piece began by creating a master pattern to produce the cast bronze castings. Each casting was hand polished to a satin finish followed by a hand-applied, hot patina finish for an aged appearance. Every component of this elaborate system had to be cosmetically flawless and mechanically functional. There were thousands of components required to complete this job and each one had to meet the highest standards of quality and match in color and finish. The completed project is an artistic display of functional design.
