There are few sights more iconic in Boulder than the University of Colorado campus, where the red-tiled roofs gleam under the Colorado sunshine, framed by the dramatic rise of the Flatirons and Green Mountain beyond. This timeless view blends architecture and nature in a way that feels uniquely Boulder—a campus that isn’t just a place of learning, but also a postcard of the Rocky Mountain West.

The Signature Red-Tiled Roofs

The university’s signature red roofs, inspired by Italian Renaissance architecture, are more than just beautiful—they’re symbolic. Designed in the 1920s by architect Charles Klauder, the style became known as “University of Colorado Tuscan Vernacular.” The warm terracotta roofs, buff-colored sandstone walls, and elegant arches create a cohesive look that has defined CU’s identity for nearly a century.

Fun fact: the sandstone used to build many of these buildings was quarried locally from Boulder’s own Flatirons. That means the campus isn’t just sitting at the foot of the mountains—it’s literally built from them.

A Campus Framed by the Flatirons

Few universities in the country can claim such a dramatic backdrop. The Flatirons, those iconic slanted rock formations, rise like sentinels above the city. Behind them lies Green Mountain, a favorite spot for hikers and trail runners who want to soak in panoramic views of Boulder Valley. For students, this isn’t just scenery—it’s a daily reminder of adventure waiting just beyond the lecture hall.

Fun Facts About CU’s Campus

• Historic Landmarks: Old Main, built in 1876, was the very first building on campus and still stands today.

• National Recognition: CU Boulder has been consistently ranked among the most beautiful college campuses in the United States.

• Architectural Consistency: Every new building constructed on campus follows Klauder’s original red-roofed, sandstone design guidelines, ensuring CU keeps its timeless charm.

Why It Matters
