Like a number of other Polish churches in the so-called Polish Cathedral style such as St. Josaphat's Basilica in Milwaukee or Immaculate Heart of Mary in Pittsburgh, the architectural firm of Worthmann and Steinbach modeled the church's design on St. Peter's Basilica in Rome [REF].
In 1948, in preparation for the parish's Golden Jubilee, John A. Mallin decorated the interior of the church with ornate designs and paintings.
