Grey Towers Castle

Grey Towers Castle is a building on the campus of Arcadia University in Glenside, Pennsylvania which is in Cheltenham Township, a suburb of Philadelphia, USA. The castle was designed by Horace Trumbauer and built starting in 1893 as the estate of William Welsh Harrison. The university purchased the estate in 1929 for $712,500, equal to $10,608,794 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.

In 1891, William Welsh Harrison, co-owner of the Franklin Sugar Refinery, purchased Rosedale Hall from J. Thomas Audenreid. By 1891, Harrison had expanded his estate to 138 acres and decided to expand the house and add a gate house and more adequate stables. He employed the skills of 23-year-old architect Horace Trumbauer, who completed the stables and gate house in 1892.
