Glen Foerd on the Delaware is a historic mansion and estate built as a summer home circa 1850 in the Italianate style by Charles Macalester, Jr., a prosperous businessman and banker who held close personal relations with Presidents Jackson, Van Buren, Polk, Pierce, Buchanan, and Lincoln. In 1893, Robert H. Foerderer, a U.S. Congressman and industrialist, purchased the estate and gave it its present name. He enlarged the house in 1903 in the Edwardian Classical Revival style. The estate was listed on the National Register of Historic Places in 1979.
