The Grey Towers Castle is a building on the campus of Arcadia University in Glenside, Pennsylvania, which is located in Cheltenham Township, a suburb of Philadelphia, United States. The castle was designed by Horace Trumbauer and built starting in 1893 on the estate of William Welsh Harrison.
The university purchased the estate in 1929 for $712,500, equal to $12,642,733 today. Classes were split between the two locations until 1962, when the school moved all of its operations to the Glenside area. The castle was designated a National Historic Landmark in 1985 for its architecture.
