This beautiful Romanesque church was built ad majorem Dei gloriam (“to the greater glory of God”) in 1891. The architect was Frederick Sauer, who gave us many distinguished churches, as well as comfortable houses, practical commercial buildings, and the whimsical Sauer Buildings built with his own hands in his back yard. This is the mother church for Polish Catholics in Pittsburgh, and it has one of the most spectacular sites for a church in the city, sitting at the end of the long broad plaza of Smallman Street along the Pennsylvania Railroad produce terminal.

The rectory is also a remarkable building, and still manages to convey much of its original impression in spite of the unfortunate glass-block infestation.
