The Archdiocese of Chicago celebrated the historic election of Chicago-born Pope Leo XIV on June 14 at Rate Field, home of the White Sox.

Later in the afternoon, the 133 electors will gather in the Pauline Chapel of the Apostolic Palace for prayer before processing to the Sistine Chapel, where the conclave will begin.

Cardinals entered St. Peter’s Basilica on Wednesday for a final Mass before the conclave to elect the successor to Pope Francis after his death last month.
