Saint Adalbert's is a historic church in the Pilsen section of Chicago. Modeled after St. Paul’s Basilica in Rome, it includes stained glass windows depicting Polish saints Casimir and Stanislaus Kostka, a testament to the parish's origin serving the city's Polish population. Today St. Adalbert’s also serves Pilsen’s Mexican community, evident by the shrine of Our Lady of Guadalupe. Services are offered in both Polish and Spanish.
