Colorado Historical Society
Since 1879, this institution has been the keeper of Colorado's stories—housing everything from dusty archives to carefully preserved artifacts that tell how the state became what it is today. More than a million visitors walk through annually to experience curated exhibitions, dig through manuscript and photograph collections, or catch one of the educational programs designed for all ages. The winter months bring a particular coziness to exploring these indoor galleries, where you can warm up while discovering the people and moments that shaped this corner of the country. Beyond the main buildings, historical markers scattered across Colorado's landscape and a steady stream of publications help bring the past into everyday life. The organization's work spans collecting and caring for materials that might otherwise vanish, offering archaeological and historical consultation to communities, and running hands-on learning opportunities that make history feel connected to the present rather than locked away behind glass.
