[3] Located on Polish Hill in Pittsburgh, Pennsylvania, it is a prime example of the so-called 'Polish Cathedral' style of churches in both its opulence and grand scale.

In 2019 it was reorganized as a personal (non-territorial) parish within the Shrines of Pittsburgh, a grouping of six churches with unique histories which the diocese hoped to promote as pilgrimage and visitor destinations.

William P. Ginther, a prolific Akron, Ohio, architect who specialized in ecclesiastical buildings,[9] designed the new structure.

The cornerstone was laid on July 31, 1904,[6] and the completed church was dedicated by Diomede Falconio, Apostolic Delegate to the United States, on December 3, 1905.

The church is constructed from brick in two contrasting colors, gray and brown, with Indiana limestone trim.
