Many sites associated with past popes’ lives have become museums or holy destinations for the faithful. But Pope Leo XIV’s childhood church in Chicago closed years ago.

Chicago’s South Side was solidly working class during Pope Leo’s childhood, said Rob Paral, a researcher at the Great Cities Institute at the University of Illinois Chicago. The family attended a South Side church, but they lived in Dolton, a suburb just past the city line.

This morning, the city of Chicago — famously known as the City of Big Shoulders — is embracing one of the biggest honors in its history: the election of one of its own as the first American pope.
