One summer morning in 1852, Fred Graue entered his mill and turned the wheel that opened the sluice gates outside. Water from Salt Creek rushed into the millrace and the wooden waterwheel began to turn for the first time. It would turn the machinery that would grind grain for the next seventy years.
Today, Graue Mill is the only operating waterwheel gristmill in Illinois, and one of only three authenticated Underground Railroad stations in the state.
