The Longmont Museum is a center for culture in Northern Colorado where people of all ages explore history, experience art, and discover new ideas through dynamic programs, exhibitions, and events.

he Longmont Museum was founded in 1936. In 1940, the first exhibits opened to the public in the carriage house at the Callahan House. The Museum outgrew that space, and, in 1954, moved to the basement of the Memorial Building in Roosevelt Park.

In November 1999, Longmont voters approved $5 million in a bond issue to build a new museum. The bond issue was approved by over 77 percent of voters. The Longmont Museum & Cultural Center was further enhanced by a $1 million gift from the Bill and Lila Stewart family. Now located at 400 Quail Road, just east of Main Street in south Longmont, the Longmont Museum invites visitors to come and see our regularly changing exhibits, experience our education programs, and enjoy the views from our Longs Peak Room tower.

In 2015, the Museum opened the Stewart Auditorium, an 11,000 square foot expansion made possible by a $4.5 million capital campaign. The expansion includes the 250-seat Stewart auditorium and Cone-Shortall stage, the glass-walled Swan Atrium, and the Kaiser Permanente Education Center, which greatly expands the Museum's classroom space.
