Whitemarsh Hall was a large estate located on of land in Wyndmoor, Pennsylvania, US, and owned by banking executive Edward T. Stotesbury and his wife, Eva. Designed by the Gilded Age architect Horace Trumbauer, it was built in 1921 and demolished in 1980. Before its destruction, the mansion was the third largest private residence in the United States. Today, it is regarded as one of the great losses in American architectural history. Despite the name, Whitemarsh Hall was located in Springfield Township, not in Whitemarsh Township which borders Springfield to the west. History Construction and appointments Designed by the inspired autodidact Beaux-Arts architect Horace Trumbauer between 1916 and 1921, Whitemarsh Hall consisted of 6 stories (3 of which were partly or fully underground), 147 rooms, 45 bathrooms, , and specialty rooms including a ballroom, gymnasium, movie theatre, and even a refrigerating plant.

The French 18th-century furniture was purchased through Lord Duveen, who had guided Stotesbury in assembling the second of America's great collections of English portraits, and the floor was lined with exquisite Oriental rugs, also purchased under the guidance of Duveen. Duveen also advised Stotesbury in purchases of French sculpture to decorate the huge mansion. The gardens and landscaping were designed by the great urbanist and architect Jacques Gréber, whose designs in the grand manner of André Le Nôtre for the Philadelphian P.A.B. Widener at Lynnewood Hall had recommended him to Trumbauer and to Eva Stotesbury, who moved into a house next to the estate to follow the progress of construction at close hand.
