Immaculate Heart of Mary Parish, located at 3058 Brereton Street in Pittsburgh's Polish Hill neighborhood, was founded in 1897 as a Polish ethnic parish. It was the third Polish parish in the Diocese of Pittsburgh and served as a spiritual and cultural center for Polish immigrants who settled in the area. The church building, dedicated in 1905, was designed in the Polish-Catholic style and modeled after St. Peter's Basilica in Rome. It features a grand central dome, eight altars, and 53 stained glass windows imported from Austria. The church has a rich history of welcoming notable visitors, including Cardinal Karol Wojtyla (later Pope John Paul II), and has maintained its Polish traditions, including the Divine Mercy novena, which it pioneered in 1979.

The parish continues to serve the local community with regular Mass times, sacraments, and a variety of ministries. Mass is offered at 10:00 AM on Sundays and 4:30 PM on Saturdays.
