It is a large, two story brick structure with limestone trim, designed by Timothy G. O'Connell and built in 1914 to serve the city's growing Polish-American population.

The interior in particular is decorated with symbols generally found in Catholic churches in Poland, including the Polish eagle.

It has a basically rectangular plan, with a gabled roof along its length crowned by a tall tower at the front.

There are entrances on the sides of this latter projection and in the center of the main facade, each set in a round-arch opening with rounded windows above.

Above each entrance are complexes of tall round-arch windows, the central one rising to the roof level as part of the base of the tower.
