St. Mary of the Assumption, Glenshaw
St. Mary was founded in 1840 in the area then called Pine Creek, now Glenshaw. The origins of the church can be traced to 1835 when a group of local Catholics took it upon themselves to build a log church. The church served as a mission of St. Patrick, Strip District until 1839, when it became a mission of St. Philomena. On August 15, 1840, the property upon which the church was located was transferred by deed to the Bishop of Pittsburgh. This marks the beginning of the parish, although it still continued as a mission of St. Philomena. Not until November 1847 was a resident pastor assigned to the church.
This church served the congregation until 1866 when it was torn down and replaced by a larger brick church in 1867. This second church served the congregation for nearly a century. The movement of population from the city of Pittsburgh to the suburbs in the 1950's and 1960's led to the need of a larger church. The new church was dedicated on August 30, 1964.
