The Pillsbury A-Mill, situated along Saint Anthony Falls on the Mississippi River in Minneapolis, Minnesota, held the title of largest flour mill in the world for 40 years. Completed in 1881, it was owned by Pillsburyand 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 is currently abandoned (Courtesy of Wikipedia).
Looks like "abandoned" Mill is in process of becoming "Condos for sale." Work proceeds at torrid pace.
