Let me now talk about the history of Monongahela. What is now the city of Monongahela was actually founded in the year 1769 on a tract of land near the confluence of the beautiful pigeon creek and the Monongahela River. You should also know that it is one of the oldest settlements near the river and the valley and it is also most likely the oldest in the entire Washington County. The original land was owned by three different men who named it Eden, Gloucester and Paradise. There was a man called Joseph Parkinson, and he operated a ferry on the West bank of the river, and he was recognised as the founder of the entire place. He built the first Post Office in the town and in the year 1782, the town was officially recognised as Parkinson’s ferry. Some people claim to almost 130 acres of land.

The word ‘Monongahela’ is actually a native American word in origin, and it means “following banks”. The tribe of Monongahela was indigenous in nature, and this was before the settlement of the city.

Monongahela is a home for a lot of parks, museums and playgrounds. Chess Park is located near the centre of the city, and it hosts a community. They have community events throughout the year. There is a park called the mounds park, and it is built on the site of an ancient Indian burial ground, which is also a local playground and a sports complex.
