was quickly realized after the war ended. Pennsalt kept the mansion and its remaining grounds maintained and modernized, and constructed some new facilities on the property as well. In 1963, Pennsalt (later renamed Pennwalt) built a new research center in the King of Prussia area, and moved out of Whitemarsh Hall, which was sold to a property investment group. Efforts to preserve or sell the mansion intact by this and successive owners were unsuccessful, and as the property became neglected and vandalized over the following years, demolition was decided upon. Disputes over the form of residential redevelopment to be undertaken (especially plans which envisioned luxury apartment towers) delayed demolition for a number of years. The site today The mansion, which was larger than the White House in Washington, D.C. was demolished in 1980, and a development of modern townhouses called Stotesbury Estates was built on the property. The massive limestone pillars which were part of the mansion's front portico were left in situ as a tribute, along with the large belvedere at the back of the home. No homes occupy the footprint of the mansion itself, whose basements and foundations were simply backfilled. Small remnants of the huge gardens still exist today, including a fountain, several statues, stairs, and pieces of low stone fence and walls. The twin pillars of the estate's main gate, which was one mile (1.6 km) from the back of Whitemarsh Hall, are still standing on Douglas Road off Willow Grove Avenue, minus the steel gates. The gatehouse on Douglas Road, behind the main entrance pillars, also remains, converted to a private residence.
