Glen Foerd on the Delaware is a historic mansion and estate located in the Torresdale neighborhood of Philadelphia, Pennsylvania, overlooking the Delaware River. The mansion, then named Glengarry, was built as a summer home about 1850 in the Italianate style by Charles Macalester, Jr., a prosperous businessman and banker. In 1893, it was purchased by Robert H. Foerderer, a U.S. Congressman and industrialist, who gave it its present name. He enlarged the house in 1903 in the Edwardian Classical Revival style. In 1971, the estate was given to the Lutheran Church in America. In 1985, Glen Foerd Conservation Corporation and the Fairmount Park Commission assumed ownership of the property.
