The mill was constructed using locally sourced timber and stone, reflecting the architectural standards of the 1850s.
The Salt Creek waterway provided the necessary hydraulic power to turn the mill's massive wheel, which drove the grinding stones.
Frederick Graue was a German immigrant who designed the mill to process wheat and corn for farmers across DuPage County.
The mill's location made it an ideal, discreet refuge for escaping enslaved persons moving toward Chicago and northern transit points.
Restoration efforts in the 1950s involved significant structural work to return the waterwheel to operational status.
The site remains one of the few places in the Midwest where authentic, water-powered stone-grinding processes are still demonstrated for the public.
Graue Mill & Museum is an operating 19th-century water-powered gristmill located along Salt Creek in the Fullersburg Woods Forest Preserve. Built in 1852 by Frederick Graue, the structure served as a vital regional hub for milling grain. It is famously recognized as a documented station on the Underground Railroad, where enslaved people sought refuge during their flight to freedom. The site features a restored wooden waterwheel and authentic milling machinery that remains functional. Visitors can observe live demonstrations of corn grinding and bread baking performed in period attire. The museum also houses local history exhibits documenting 19th-century frontier life and the regional timber industry. The facility is managed in partnership with the DuPage County Forest Preserve District. It provides an educational look at mid-1800s industrial technology and humanitarian efforts in Northern Illinois.
