Situated on the east bank of the Mississippi in Minneapolis, Minnesota, the Pillsbury Flour Mill took advantage of the power produced by St. Anthony Falls to produce 17,500 barrels of flour per day. Pillsbury A Mill was added to the list of National Historic Landmarks in 1966. Of the four large flour mills in the city during the peak of Minneapolis’s reign as the milling capital of the country, the Pillsbury A Mill is the only one remaining.

The Pillsbury A-Mill, seen here behind the Stone Arch Bridge, held the title of largest flour mill in the world for 40 years. Completed in 1881, it was owned by Pillsbury and operated two of the most powerful direct-drive waterwheels ever built, each generating 1,200 horsepower (895 kW). The mill still stands today on the east side of the Mississippi River and has been converted into resident artist lofts.
