Outdoor Picture of the Day: Historic Old Main at the University of Colorado Boulder

Today’s Outdoor Picture of the Day captures one of the most iconic landmarks in Boulder, Colorado — Old Main at CU Boulder — standing gracefully beneath a winter sky.

With snow resting gently along its rooflines and the Flatirons rising behind it, Old Main at the University of Colorado Boulder becomes even more powerful in winter. The red-brick structure contrasts beautifully against fresh snowfall, creating a timeless Boulder scene that blends history, architecture, and natural beauty.

Old Main is the oldest building on the CU Boulder campus. Construction began in 1876 — the same year Colorado became a state — and the building officially opened in 1877. When the University of Colorado first welcomed students, Old Main housed everything: classrooms, administrative offices, and even living quarters. In the earliest days of the University of Colorado Boulder, this single building was the entire campus.

Today, Old Main remains central to campus life at CU Boulder. It houses key administrative offices, including the Office of the Chancellor, reinforcing its continued importance within the University of Colorado system.

Architecturally, Old Main reflects 19th-century Italianate design influences, visible in its symmetrical facade, tall windows, and detailed brickwork. The building’s warm red sandstone and brick exterior make it instantly recognizable to students, alumni, and visitors to Boulder, Colorado. In winter, the snow softens its edges and highlights the structure’s historic character.

The University of Colorado Boulder was founded in 1876 and is the flagship campus of the University of Colorado system. From its modest beginnings with a small group of students to today’s nationally recognized research university, CU Boulder has grown dramatically. Yet Old Main remains the symbolic heart of the campus.

Walking across the snow-covered lawn in front of Old Main during winter feels like stepping through history. Generations of CU Boulder students have passed through its doors — through world wars, economic shifts, cultural movements, and technological revolutions. The building has quietly witnessed nearly 150 years of transformation in Boulder, Colorado.

Old Main is more than just a historic structure at the University of Colorado Boulder. It represents resilience, growth, and academic excellence. For alumni returning to CU Boulder, it often serves as the most recognizable and nostalgic landmark on campus.

In winter especially, Old Main stands as a visual anchor. While the campus continues to evolve with modern research facilities and expanded programs, this building reminds the University of Colorado community of where it all began.

Today’s Outdoor Picture of the Day captures not just Old Main at CU Boulder, but the enduring spirit of the University of Colorado Boulder itself.

In the quiet stillness of winter in Boulder, Colorado, Old Main feels timeless — a foundation of history standing strong beneath the snow.
