History.
What is now the City of Monongahela was founded in 1769 on a tract of land near the confluence of Pigeon Creek and the Monongahela River. It is the oldest settlement in the Monongahela River Valley and most likely the oldest in Washington County. The original tract of land was actually owned by three different men, who named their land areas Eden, Paradise, and Gloucester. Joseph Parkison, who operated a ferry on the west bank of the Monongahela River, is recognized as the founder of Monongahela. Parkison built the town's first post office, and in 1782 the town was officially recognized as Parkison's Ferry. Adam Wickerham took claim to on the Parkison Ferry tract, July 1, 1788. On this tract he laid out Georgetown in 1807. Georgetown was made part of Williamsport by him on February 23, 1816. In 1833 the first borough officers were elected for Williamsport. On April 1, 1837 Williamsport was given the name Monongahela City and in 1893 shortened to Monongahela.
The word Monongahela is Native American in origin, meaning "falling banks". The Monongahela tribe was also indigenous to the area prior to the settlement of the city.
The Edward G. Acheson House, Bethel African Methodist Episcopal Church of Monongahela City, David Longwell House, and Monongahela Cemetery are listed on the National Register of Historic Places.
