Explore 500 million years of Illinois' natural and cultural heritage. Discover the diverse Illinois landscapes from a shallow sea home to monstrous sea life; to a land of ice where Mammoths walked; to a lush prairie where Bison roamed and American Indians built vast cities; to a frontier full of promise. The Illinois State Museum is home to three floors of exhibitions that tell the story of Illinois' land, life, people, and art.
Visitors will learn about Illinois' natural past through interactive elements, thrilling audio and video effects, life-sized dioramas including the Mastodon and the giant Jefferson's Ground Sloth, and thousands of fossils and zoological specimens that tell the story of Illinois' changing landscapes. Other exhibitions tell the stories of Illinois' people including the American Indians who called the land home for over 10,000 years and the Europeans who settled the prairies of Illinois. Changing exhibitions highlight the latest scientific research and share Illinois' rich artistic heritage with exhibits of fine and decorative art by Illinois artists.
Youth can visit the Mary Ann MacLean Play Museum to experience working at a museum through play. Interactive activities include digging for Ice Age fossils, collecting and studying specimens under a microscope, creating art and history exhibits, and more. Play Museum hours are Monday-Saturday 9 am - 3:30 pm; Sunday 12 pm – 3:30 pm.

Check out the ISM's new Route 66 Oral History Project!! Click HERE to listen to the interviews they produced with legendary Route 66 people!
The Illinois State Museum Route 66 Oral History Project is a collection of 100 oral interviews. Many of the subjects lived, worked, and traveled along Route 66 in its heyday. Many others have worked or are working to preserve and interpret the Mother Road. Museum team members conducted these oral histories between 2024 and 2025. They are being launched in connection with the 100th anniversary of Route 66. We hope they will help people learn about Route 66 and its impact on America’s people, history, and culture.
