Hello all!

This is just a reminder that, due to loosening COVID restrictions, you no longer need to make reservations to visit the Interpretive Center. However, masks are still required in the building.

Indian Market Days were a huge success!

We are so grateful to all of our artists for sharing their time and their work with us. We couldn’t have made this happen without them and without all of those who came to shop! For three days the Interpretive Center buzzed with activity as people came from all over came to see both traditional and contemporary Indian crafts on display. Thank you again to everyone involved!

Saint Louis Art Museum Shows Art Inspired by Cahokia Mounds

The Saint Louis Art Museum is featuring works by artist Elias Sime.  “On an unusually warm day in December 2019, Sime and his creative partner, curators and anthropologist Meskerem Assegued visited St. Louis in preparation for the exhibition Currents 118: Elias Sime. Their first destination was Cahokia Mounds State Historic Site, where they viewed the mounds of the ancient Native American city directly across the Mississippi River from St. Louis. Sime’s focus on global phenomena extends beyond contemporary systems of communication and exchange to ancient histories of art and architecture and their unique visual languages. Standing on Monks Mound, Sime and Assegued discussed Ethiopia’s own historic mounds, which were built between the 8th and 15th centuries. With only one day in St. Louis before heading back to Ethiopia, there was just enough time to see the Gateway Arch, a St. Louis landmark and an outstanding achievement in sculpture and engineering.

The exhibit titled Tightrope: Eyes and Ears of a Bat 1 and 2. These large-scale, concave bowls invert the iconic forms of the mound the arch. The half-spherical shapes are covered with wires and electrical components, like freestanding versions of Sime’s iconic wall-hung assemblages. Braided and twisted electrical wires nailed into the bowls’ surfaces evoke both movement in nature and painterly brushstrokes. Sime chose their brown, terra-cotta, and green colors to allude to the shades of the Midwestern winter landscape he saw from the vantage point of Monks Mound. Through its unique materiality, Sime’s art expresses an astute commentary on environmental sustainability, the power of nature, global social connections, and the beauty of the utilitarian.”

The exhibit closes January 31, 2021. For more information on visiting check SLAM’s website.

CMMS & PARC Host Virtual Trivia Night

On Saturday October 24, Cahokia Mounds Museum Society is partnering with Powell Archaeological Research Center to host their Annual Trivia night a little differently. Our normal trivia night was postponed due to COVID-19 and in person events will likely not be taking place any time soon so we are taking it virtual. 

Powell Archaeological Research Center processes and catalogs everything found during our summer digs. They are also a non profit organization and rely solely on donations to pay for all expenses that they incur in processing these items. 

In order to participate in Trivia night, each household must have a computer or tablet or any device that they can access Zoom on as that will be the platform we use for the evening’s events. Each participant will also need a separate device to actually answer the questions. Kahoot! is an app that allows participants to answer questions and the person who answers correctly gets the most points. It’s every person for themselves. Have friends over and compete against each other! Tickets are $15 plus applicable fees and can be purchased at Eventbrite

We will have Steve Shininger providing some entertainment throughout the night. 

If you have any questions please email or call (618) 344-7316.




Interpretive Center Closing on Wednesdays

Beginning the week of September 21, Cahokia Mounds State Historic Site will reduce Interpretive Center open days to 4 days per week, Thursday through Sunday. Grounds will remain open daily from dawn until dusk. This is due to recent reductions in staffing as well as the effects of the pandemic on our human resources. We anticipate this schedule to remain throughout the winter months and hope that you continue to support Cahokia Mounds during our new schedule. We are working hard to maintain programming and implement new programming that conforms to the constraints the pandemic has imposed on us. You can find more information on our website and social media outlets as it becomes available.

Governor Pritzker Visits Cahokia Mounds

On Aug 27th we had the honor of hosting Governor J.B. Pritzker and the First Lady. They visited the Interpretive Center and received a tour led by Bill Iseminger. The Governor asked many questions about the history of the Mississippians and also asked many questions about the site. They also made the trip up Monks Mound where Bill also led a short tour. It was an honor to have them visit.
