Just south of downtown, the first Polish basilica in North America is the city’s St. Josaphat’s Basilica (Lincoln Ave. at S. 6th St., 414/645-5623, tours by appointment, but public welcome to Masses). Parishioners built the structure out of salvaged rubble from the Chicago Federal Building. The capacious dome is modeled after St. Peter’s in Rome; inside is a rather astonishing mélange of Polish iconography and hagiography, relics, stained glass, and wood carvings.
