Gladden Windmill
Also known as: Milks Windmill

Why it's listed
Gladden Windmill, also called Milks Windmill, is a four-story wood-frame vertical windmill on a stone foundation on Pigeon Valley Road in Napoli, New York. Three lower stories held the milling machinery, and the fourth held a revolving windwheel about 11 feet high and 19 feet across, ringed by 16 shutters that directed wind into the wheel. Its frame uses hand-hewn beech timbers, with tall hemlock corner posts. A farmer named Gladden, wanting to avoid the long trip to a gristmill, saw a similar design near Lincoln, Nebraska, in 1888 and acquired rights to build one. The foundation was laid in fall 1890 and the mill was finished a year later. It powered grain grinding, cider pressing, a lathe and a repair shop. The nomination calls it an uncommon piece of industrial architecture and a farmer's ingenious solution to productivity. The mill no longer operates, and its vanes have been removed, but the structure is largely intact.
Significance in brief: The nomination argues the mill is a significant piece of industrial architecture with an uncommon vertical windwheel and shutter design, perhaps otherwise vanished in the United States. It is described as a unique, ingenious answer to one farmer's search for convenience and productivity. It is largely intact apart from the removed vanes.
