The Wye Grist Mill is located in the Town of Wye Mills, on Maryland's Eastern Shore. The Wye Grist Mill has been nearly continuously grinding grain since 1682, and produced flour that fed George Washington's Continental army during the American Revolutionary War.

Discover the long and rich history of the oldest commercial operation in Queen Anne's and Talbot Counties (the county boundaries run through the mill).

Watch the waterwheel turn the heavy millstones as they grind grain, with millers explaining the milling process. 

Explore our exhibits - featuring over 325 years of the food processing technology used here.

Oliver Evans Schedule

Father of the Industrial Revolution

The 3rd United States patent, granted in 1790 and signed by then President George Washington, was granted to Oliver Evans for his process to automate grist mills.

Oliver's invention allowed grist mills to produce a higher quality flour - with much lower labor expenses.

The Wye Grist Mill was one of the first mills to be automated with the Evans process, still in use today at the Wye Grist Mill.

Oliver Evans also invented the high pressure steam engine, and was the first to design and build a wheeled vehicle powered by an engine.
