The Longmont Museum serves as a cultural hub in Northern Colorado, focusing on the history, art, and anthropology of the St. Vrain Valley. The facility houses a permanent exhibition titled 'Front Range Rising,' which tracks the regional timeline from ancient indigenous history to modern-day agricultural and industrial development. It features a rotating schedule of world-class traveling exhibits, covering topics ranging from photography to global cultural history. The building functions as an active civic space, incorporating an outdoor courtyard and the Stewart Auditorium for performances and film screenings. Its collection includes extensive archives of historical artifacts, textiles, and photographs documenting Longmont's growth from a colony founded in 1871.
