English: The baroque interior of St. John Cantius Church. Designed by Adolphus Druiding and completed in 1898, St. John Cantius Church took five years to build and is one of the best examples of sacred architecture in the city. The unique baroque interior has remained intact for more than a century and is known for both its opulence and grand scale—reminiscent of the sumptuous art and architecture of 18th century Krakow. The imposing 130 ft. tower is readily seen from the nearby Kennedy Expressway. In 2013, St. John’s completed an ambitious restoration, returning the lavish interior to its original splendor. Of all the “Polish cathedrals” in Chicago, St. John’s stands closest to downtown. Located in the heart of Chicago, one mile directly west of the famous Water tower on Chicago Avenue, St. John Cantius Church is easily accessible by car, bus, or subway.
