Gladden Windmill
Gladden Windmill is an historic windmill formerly located on Pigeon Valley Road in Napoli, Cattaraugus County, New York. The windmill was built in 1890 and is a well-preserved example of a vertical wind turbine built during the 19th century. Although no longer operational, the turbine is a rare example of wind power technology in the United States.
It was listed on the National Register of Historic Places in 1973. Since its listing, the windmill has been dismantled and moved to Conewango, New York.
