Hatfield House
It was built as a suburban villa in 1760, in what is now the Nicetown neighborhood of the city. It operated as Catherine Mallon's Boarding School for Girls from 1806 to 1824. William J. Hay was the next owner, and made major Greek Revival-style alterations – including the addition of the unusual 5-column temple portico – in 1838. Dr. Nathan L. Hatfield, of the University of Pennsylvania, bought it in 1854; his family owned it for 75 years. Recently the building has undergone some restoration in an attempt to return it to its past glory. -from Wikipedia
