Museums & History

Longmont's modern history dates back to 1870.

A group of prominent Chicago men established the "Chicago-Colorado Colony" before naming the town Longmont upon its completion in 1871. Longmont has three designated historic districts and nine locations on the National Register of Historic Places.
