Until 2015, near the eastern border with Chalfant, there once stood an historic, five-million-volt Van de Graaff generator and particle accelerator known as the Westinghouse Atom Smasher.[11][12] The Atom Smasher operated from 1937 to 1958, and because of many important discoveries that were made using the device—it was designated an official historic landmark in 2010.[13] However, the apparatus was torn down in 2015, when the property that had served as the primary campus of the Westinghouse Research Laboratories from 1916 to 1956[14] was being prepared for redevelopment.[15][16]

Forest Hills is known for its many recreational and family oriented activities.
