Fallsington is an example of a crossroads community typical of the 18th century, on the Kings Highway (now U.S. Route 13). The Bucks County Courthouse, established in 1663, is said to have been located in Fallsington until it was moved to Bristol in 1705. The first meetings of the Religious Society of Friends were held in the home of William Biles on Biles Island. Falls Monthly Meeting found a site for the first brick meetinghouse built in Fallsington, about 1690, on 6 acres (0.024 km2) of land that had been donated by Samuel Burgess. Also in 1690, Thomas Janney donated 72 acres (0.29 km2) of land to be used as the Quaker burial grounds for Falls Monthly Meeting. William Penn donated a tract of 120 acres (0.49 km2), for a Falls commons.
Fallsington evolved through a succession of periods in American history and architecture. Significant homes in Fallsington range from the late 17th century through the Victorian era of the mid-19th century. Fallsington was a center of commerce. A business directory of the 1860s listed blacksmiths, a butcher, carpenters, a carriage builder, a cooper, farmers, an insurance agent, machinists, physicians, a surveyor, and a wheelwright.
The growth of Fallsington continued, with the construction of homes, an inn, public buildings, stores, and small craftsmen's shops. Until the construction of Fairless Hills and Levittown, it was the largest settlement in the Township, and functioned for many years as a commercial center.
The Fallsington Historic District was listed on the National Register of Historic Places in 1972.
