As one of the seven original townships of Allegheny County, Moon Township has a long and rich history. From the humble home of Joshua, John, and Jacob Meek in what is now Crescent Township to the Stoops House, owned by 19th-century riverboat captain William Stoops, todays Moon Township is a byproduct of these modest roots. Formed in 1788, Moon Townships history crosses borders into neighboring Findlay and Crescent Townships, which once comprised Moon. Today Moon Township is recognized as one of the most bustling and vibrant communities in the suburbs of Pittsburgh. Home to portions of Pittsburgh International Airport, a growing commercial corridor, and hundreds of new families each year, Moon Township is a major player in the future of western Pennsylvania. Through vintage photographs, Moon Township chronicles how this area has changed with the times while preserving as much of its history as possible.
