The Virginia Tillery Round Barn is a round barn located on County Route 738 west of White Hall in Greene County, Illinois. The barn was built in the fall of 1912 for farmer Harry C. Price. With a 36 feet 6 inches (11.13 m) diameter, the barn is relatively small for an Illinois round barn; the median diameter of Illinois round barns was 60 feet (18 m). Its size suggests that it served as a general-purpose barn, not a dairy barn like the state's larger round barns.
