Heritage Days
McConnells Mill

Come see history in motion at the Annual Heritage Festival at McConnells Mill State Park. The Festival celebrates the time the historical gristmill operated—1852 to 1928. Costumed vendors will offer crafts inspired by the era. You can take a leisurely stroll, sit and enjoy the bluegrass music or enjoy a free tour of the mill.

The historic gristmill is full of the fascinating machinery used for grinding the grain for the community that surrounded Slippery Rock Gorge. A Civil War encampment adds to the historical setting, demonstrating the way soldiers lived and artisans and craftsmen will exhibit the skills of the time.

Heritage Days offer fun and learning for the entire family.
