The Borough of Thornburg is located in Southwestern Pennsylvania, approximately 4 miles from downtown Pittsburgh. Surrounded by scenic hillsides and situated on a bluff, the community overlooks Chartiers Creek and valley. The Borough was the site of the first railroad built in Pennsylvania to take coal to market in 1849 and is a significant example of early suburban planning. Today, Thornburg residents continue to enjoy a pastoral setting, complete with parks and recreation, with convenient access to the city.
The Borough of Thornburg, Pennsylvania, was originally founded in 1899 when cousins, Frank and David Thornburg formed a company to develop 250 acres into a suburban community.
