Wells Fargo Center

1700 Lincoln St, Denver, CO 80203

Known affectionately as the 'Cash Register Building' due to its unique curved roofline, this skyscraper is a fixture of the skyline. This iconic shape was a strategic response to Denver's 'mountain view' ordinances to avoid blocking views of the Rockies. The building features a massive three-story lobby made of elegant rose-colored granite. A sophisticated heating system is integrated into the architecture to prevent snow buildup on its unique glass curves. It remains one of the most recognizable examples of late-century corporate architecture in the American West.

Denver Art Museum

100 W 14th Ave Pkwy, Denver, CO 80204

The Frederic C. Hamilton Building is a jagged, titanium-clad structure designed to mimic the peaks of the Rocky Mountains. Its walls lean at sharp angles, ensuring there is not a single vertical wall in the entire structure. This deconstructivist masterpiece is considered one of the most challenging engineering feats in the city's history. It utilizes a complex internal steel skeleton to support its highly irregular and cantilevered shape. The design successfully reflects the crystalline formations of local minerals found throughout the Colorado landscape.

Inside, a perforated concrete ceiling allows soft, diffused natural light to fill the quiet gallery spaces. These light conditions were specifically designed to protect and highlight the massive abstract expressionist paintings found within.
