St. John Cantius Church is a historic church of the Roman Catholic Archdiocese of Chicago known for its solemn liturgies and rich program of sacred art and music.
Along with such monumental religious edifices as St. Mary of the Angels, St. Hedwig's or St. Wenceslaus, it is one of the many Polish churches that dominate over the Kennedy Expressway.
The unique baroque interior has remained intact for more than a century and is reminiscent of the sumptuous art and architecture of 18th century Kraków. Of all the Polish Cathedral style churches in Chicago, St. John Cantius stands closest to downtown. The imposing 130 feet tower is readily seen from the nearby Kennedy Expressway and is a familiar landmark in Chicago's West Town neighborhood, located at 825 North Carpenter Street.
In 2013, St. John's completed an ambitious restoration, returning the interior to its original splendor.
