The story so far
Fallowfield Township, in brief
Wikipedia doesn’t have a history of Fallowfield Township yet. The photos, dates and memories neighbors add here are how it gets written.
Fallowfield Township is an unincorporated community in Washington County, Pennsylvania, United States. It was the sixth township to be established after the 1781 formation of Washington County, and initially stretched from Elrama north to the Ten Mile Creek in what became Union and East Bethlehem townships on the Monongahela River. Home to the John H. Nelson House, which was built c. 1895, the township was gradually downsized as various sections were sectioned off into new municipalities (Allen, Carroll, Pike Run, and Somerset townships and the borough of Charleroi). Roughly 21.3 square miles (55 km2) in size, its population was 4,300, according to the 2010 U.S. Census.
Its first post office opened in 1842. Between the 2010 and 2020 censuses its population fell from 4,321 to 4,099 (-5%).
