After the end of the Revolutionary War, an inn was built along a wagon trail that stretched from Philadelphia west over the Appalachian Mountains to Fort Pitt, now the city of Pittsburgh. A tiny settlement known as Newtown grew around the inn, today the center of Greensburg's Business District at the intersection of Pittsburgh and Main Streets. A raid by Guyasuta-led Seneca Indians accompanied by Canadian rangers burned Hannastown, the original Westmoreland County seat north of Greensburg, in 1782. Newtown became the new county seat in 1785. In 1786 the county built a log courthouse on land purchased from two residents, Christopher Truby and William Jack. Every Westmoreland County Courthouse since has stood on this site. The area surrounding the courthouse became the original borough of Greensburg, named for Revolutionary War General Nathaniel Greene and formally incorporated as a borough in 1799. In the early 1800s, Greensburg had very little growth. After 1850, Greensburg became a growing county seat with inns, small businesses and hardworking residents. It was a railroad stop and the discovery of large areas of soft coal nearby made it the center of a vigorous mining industry in the late 1800s and early 1900s. Seton Hill UniversitySeton Hill College, formerly St. Joseph's Academy, became a four-year women's institution in 1918. Greensburg became a Third-Class City on January 2, 1928. After World War II, more residential areas were developed in various sections of town. Greensburg's cultural status grew as the Westmoreland County Museum of Art opened in 1959 and the University of Pittsburgh founded their Greensburg campus in 1963, now located in Hempfield Township.
