Welcome to the Illinois State Museum


In response to Illinois’ Tier 3 resurgence mitigations, the Illinois State Museum System will temporarily close our flagship facility and Research and Collections Center in Springfield, the Dickson Mounds Museum in Lewistown, and the Lockport Gallery effective Friday, November 20, 2020. All locations will remain closed until further notice. This decision is the best course of action to ensure the safety of our patrons and dedicated staff. We will continue to offer virtual opportunities so you can experience all the Museum has to offer from the safety of your home.

The Illinois State Museum inspires exploration of Illinois' past and present to inform and enrich everyday life and to promote stewardship of cultural and natural resources for the future. The Museum's extensive collections and research activities provide the foundation for exhibitions and public programs that tell the story of the land, life, people, and art of Illinois.

The Illinois State Museum is headquartered in Springfield with branch facilities near Lewistown and Lockport.
