What stands out about Aliquippa’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The oldest church within the current boundaries of Aliquippa is Mt. Carmel Presbyterian Church (formerly White Oak Flats Presbyterian Church), established about 1793 in the New Sheffield region on Brodhead Road.
Aliquippa was founded in 1894. It was the merger of three towns: Aliquippa, Woodlawn, and New Sheffield. There is no known direct connection between Seneca nation Queen Aliquippa and the city; rather, "Aliquippa" was one of several Indian names selected arbitrarily by the Pittsburgh and Lake Erie Railroad in 1878 for stations along its route.
