Spiegel Grove " is the name given to the estate of 19th U.S. President Rutherford B. Hayes. It was so named for the large puddles of rainwater that collect beneath the towering trees following a storm. "Spiegel" is the German word for mirror - an accurate description for these nature-made reflecting pools. The Hayes Presidential Center is located within 25-acres of the President's original estate. The estate features a library, museum and home of Rutherford B. Hayes.
