This week I toured the historic Graue Mill, Oak Brook, IL, a working mill since 1852, powered by water from Salt Creek that grinds corn, wheat with 150-year old buhrstones. The mill in a four-story brick structure, by woods and a creek, was run by the Graue family for 60 years.
The mill still grinds with the giant stone gears turning. The water runs through the mill-race.
It was also used as a stop on the underground railroad. Throughout the building is a historical museum with information on its place in the underground railroad; and local history of the time period.
Here are photos from my tour:
