Johnson-Sauk Trail State Park, Illinois: Best Things to Do – Top Picks

Did you know that Johnson-Sauk Trail State Park is home to one of only a handful of authentic round barns remaining in Illinois? Ryan’s Round Barn, standing 24 m (80 feet) high and 26 m (85 feet) in diameter, was built in 1910 without a single supporting beam across its interior. This architectural marvel represents a fascinating period when Protestant religious groups designed round structures believing “the devil couldn’t hide in the corners” – because there weren’t any!
