2021 Historic Gristmill Hours are from 10:30 AM to 3:30 PM at McConnells Mill State Park.  The historic gristmill will be open to visitors Wednesdays through Saturdays and Holidays through the end of October. Free interpretive tours of the mill at 1:00 PM and 2:00 PM.  Signs inside the Mill explain the machinary, its purpose, history, and may be photographed.  For special educational tours, contact the Park Office at 724-368-8811.  Come walk through and view the fascinating gears, pulleys, and milling machines preserved since the mill closed as a commercial milling business in the 1920’s. The mill ground grains such as wheat, corn, and buckwheat using waterpower from the Slippery Rock Creek. A water turbine harnesses the power of the creek to turn the machinery.
