History
Fredericktown was established as a river community in the early nineteenth century, benefiting from its location along the Monongahela River, which served as a vital transportation and trade route in the development of southwestern Pennsylvania. The borough's growth was closely tied to the booming coal and steel industries that defined Washington County and the greater Mon Valley throughout the late 1800s and early 1900s. Like many communities in the region, Fredericktown experienced economic shifts as these heavy industries declined in the latter half of the twentieth century, yet the borough has retained its historic identity and community character.
