This may be the earliest Episcopal church site west of the Allegheny Mountains, beginning with services in a log garrison in 1765. A wood frame church was constructed in 1790 under the patronage of General John Neville and Major William Lea. This small Gothic Revival stone structure is the second on the site. The church was attributed to Philadelphia's John Notman by architectural historian James D. Van Trump because of the church's archaicizing appearance and the fact that Notman was working on the Episcopal church of St. Peter (demolished) in Pittsburgh in 1852. Although the small wooden church is a modern reconstruction, the church and the pioneer burial ground, with graves dating from the early 1800s, are an excellent reminder of Pittsburgh's preindustrial era.
