Dr. Evermor’s Forevertron, built in the 1980s, is the largest scrap metal sculpture in the world, standing 50 ft. high and 120 ft. wide, and weighing 300 tons. It is housed in Dr. Evermore’s Art Park on Highway 12, in the town of Sumpter, in Sauk County, Wisconsin, United States.
The sculpture incorporates two Thomas Edison dynamos from the 1880s, lightning rods, high-voltage components from 1920s power plants, scrap from the nearby Badger Army Ammunition Plant, and the decontamination chamber from the Apollo 11 spacecraft.
