Ghosts of the Ammunition Plant Tour

October 11, 2014
10:00 a.m. - 1:00 p.m.

Attendees will meet at the Welcome Center | Show Directions


Please note: construction on I-55 over the Des Plaines River bridge is causing major delays between Arsenal Road and Bluff Road. If this is the route you normally use to access Midewin, please check the website for alternate directions, such as I-55S to I-80E to Route 53 South (aka Chicago Street).

Did you know that in 1940, the U.S. Government acquired over 36,000 acres to build an ammunition plant on the land that is now known as Midewin National Tallgrass Prairie? Why was this location chosen? How was it built and operated?

Our volunteer tour guide for this event, Lorin Schab, is excited to share these stories and more with you. During the three-hour tour, you’ll see the inside of one of the few remaining warehouses and an ammunition storage bunker.

All attendees should meet at the Welcome Center 15 minutes prior to the start of the tour.
You will need to travel in your personal vehicle over unfinished gravel roads that include some potholes. Advanced registration is required to guarantee your spot; please call 815.423.6370 or email And provide your contact information in case we need to inform you about cancellations or changes to the schedule.
