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.

Exhibit Gets Much Needed Update

During the shutdown period our badly deteriorated outdoor mitigation porch received a facelift and a new sign. We received a generous donation to repaint and produce a sign for the outdoor feature exhibit. This area was inhabited by all four phases of occupation at the site beginning with AD 1050 through AD 1250. This is represented by four colors of paint as noted in the sign. The rectangles are where houses stood and the circular features are either pits or post holes. The oldest is the red or the ‘Lohman’ Phase. The sign also shows the difference in settlement pattern, house construction, and house size between the four phases. This exhibit was painted when the building was opened in 1989 and had not painted since (except for the blue which was updated by some volunteers about 5 years ago). There was no interpretive sign except for a foot-tall concrete block with a page on the front that was 30 years old and was no longer legible. This sign and the fresh epoxy paint is a huge facelift for the entrance of our building. It was so badly worn and weathered that about 75% of our visitors walked into it thinking it was the entrance to the building. Very proud of our team for improving this area of our facility!!


CLOSURE – Superintendent Update

The health and safety of our community, visitors, and staff are of the utmost importance during this difficult time.

Laboratory of Archaeology


Angel Mounds is one of the largest Mississippian mound centers on the northeastern Mississippian frontier. Little is understood about Angel’s relationships with surrounding hinterland communities or with other Mississippian centers in the Midwest. Recent remote-sensing research at Angel and outlying sites suggests aligning residential and mound architecture to the movements of the moon was important for over three centuries and that the broader Angel lunar landscape connected Angel to a Cahokian cosmology and to ancestral Middle Woodland histories.

Beginning Feb 1 IDOT Closes parts of I-255

Beginning February 1 please consult the Illinois Department of Transportation’s website for planned detours while parts of I-255 are closed for a major overhaul.

“While this project will require a complete closure of the interstate to all traffic for one construction season, it enables the project to be completed cheaper, faster and safer.

* Significantly reduces completion time to 10 months, instead of 4 years.
* Saves $14 million.
* Increases worker safety by keeping traffic out of the work zone.
* Reduces accidents by eliminating the need for work zone lane shifts.

The project consists of rehabilitating and resurfacing approximately 7 miles of I-255 from Collinsville Road to Illinois 15 in two sections separated by Interstate 64, with significant bridge repairs, safety improvements and drainage upgrades.  This project will restore the roadway and bridges to a smooth and safe condition for motorists and will support future investment in the region.”

Cahokia Mounds Receives Second NEH Grant

The National Endowment for the Humanities (NEH) announced today that $30.9 million in grants to support 188 humanities projects is awarded to expand access to the country’s wealth of historical resources. Cahokia Mounds Historic Site is among the recipients for the second year. The site is awarded a Digital Projects for the public grant from the NEH in the amount of $250,000 to develop an Augmented Reality (AR) Application and bring pre-Columbian history to life for visitors.

The grant was submitted by the Cahokia Mounds Museum Society (CMMS), the on-site support group at Cahokia Mounds. In 2019, CMMS was awarded a $100,000 Prototype grant to develop a prototype of an Augmented Reality Application. The prototype was developed by Schwartz & Associates Creative, St. Louis, MO. In June 2019, CMMS submitted the prototype and application for the development phase of the project. Both grants are administered by Alie Morgan, Executive Director of the Society, in conjunction with the Site.

“This has been a 5-year project, working closely with the Schwartz team, to develop cutting-edge interpretive pieces at Cahokia Mounds. It is difficult for visitors to visualize what was on the landscape a thousand years ago, a challenge for any archaeological site. This grant will enable us to provide a unique interpretive experience using the newest technologies. Available in 2021, visitors will utilize the camera on any smart device to read a code placed on the landscape. Their device screen will then populate with houses, temples, fires, people, and other features of the Mississippian landscape at around AD 1050, as if it were on the physical landscape before you,” Lori Belknap, Site Superintendent.
