The museum has gone through numerous locations and name changes since its inception in 1983, finally settling the old Post Office building in Old Town Fort Collins, with the current name. The museum owns and occupies the first floor of the building, where it presents a diverse series of exhibitions, community events, publications, and educational programs for children and adults.
The Old Post Office building is a three-story Second Renaissance Revival structure designed by James Knox Taylor, the Supervising Architect for the U.S. Treasury. Described at the time as the “finest building in the city,” the Post Office building is listed on the National Register of Historic Places and is a designated Fort Collins local landmark.
