A BIG thanks to Lynda for telling me about this place!

The mill is believed to have been constructed in 1826 and was operated continuously until the 1980's taking its waterpower from Rambo Run. The mill was placed on the Pennsylvania Inventory of Historic Places on February 24, 1977 and the National register of Historic Places on June 10, 1977. The owner Harry Cross gave the mill to York County in 1979.

Since 1840, ownership of the mill changed only four times with one name change from the family name of Wallace to Cross.

The restoration focus is the 1950 era; the pinnacle of Harry Cross' career when the mill ran 24 hours a day and seven days a week. The mill's first floor, including the office, is the area open to the public. The exhibits and demonstrations appeal to all ages but especially fifth through seventh grade students of Pennsylvania history.

A Lieberknecht mill demonstrates the milling process. A single millstone grinds the grain, and illustrates the way millstones are sharpened. A hand powered corn sheller demonstrated the removal of kernels from corncobs.

The office gives the impression that Harry Cross stepped out for a moment. It includes a stove, miller's desk, workbench and chairs.

A wooden overshot wheel with wooden spokes and shaft originally powered the mill. A Fitz wheel, manufactured in Hanover, Pennsylvania, replaced it. Fitz was the preeminent manufacturer of mill wheels in the 19th century. The original Fitz waterwheel was restored and re-installed through the kindness of Harvey Bradley.

The primary function of the mill was that of a place of business. However, the mill was frequently used as a meeting place for farmers and others.
