Tullytown Borough lies on the southern edge of Lower Bucks County along the Delaware River, between Falls Township and Bristol Township, and includes part of Levittown, Pa.

Levittown, which encompasses parts of four Lower Bucks County municipalities, started in 1951 with three sample homes on Route 13 in Tullytown. Thousands of young families, fulfilling the American dream of owning their own home, bought affordable single homes for $100 down and settlement costs of about $90.
