The Formal Gardens were constructed in 1931 by George F. and Stella Elkins Tyler to provide a formal landscape setting for their estate. The four-tier Formal Gardens were influenced by French and Italian gardens and feature varieties of flora, beautiful lush lawns, dramatic stone walls and staircases, gravel walks, fountains, and bronze sculptures. The Tyler mansion is arguably the grandest home ever built in Bucks County and believed to be the last of the great estates ever constructed in the United States. In 1987, Tyler Hall, as the mansion is known, and Tyler Formal Gardens were placed on the National Register of Historical Places.
