As one travels the John F. Kennedy Expressway on the north side of downtown Chicago, one can count the towers of five impressive church edifices that comprise the principal history of Chicago’s Polish Catholics. The heart of Chicago’s “Polonia,” the neighborhoods nearby, has been home to a large number of immigrants who came to the United States from Poland or are of Polish descent. In 1950, Chicago had the largest Polish population outside the city of Warsaw. Today, Polish is the third most frequently heard language in this city, behind English and Spanish.
