With the other religious edifices of St. Mary of the Angels, St. Hedwig's or St. Wenceslaus, it is one of the many Polish churches that overlook the nearby Kennedy Expressway.

The 130 feet (40 m) tower is readily seen from the Kennedy Expressway and is a landmark in Chicago's West Town neighborhood, located at 825 North Carpenter Street.

Vincent Barzyński of the Congregation of the Resurrection, saw the validity of this request and immediately purchased several lots at Fry and Carpenter Streets for the sum of $75,000.

Just below this on the entablature, is the Latin inscription "Ad maiorem Dei Gloriam", a text which proclaims that this building is for the Greater Glory of God, a Jesuit motto popular in many churches built around the start of the 20th century.

An inlaid hardwood floor was installed in St. John Cantius Church in 1997 in a design by Jed Gibbons.

The medallions inlaid into the main aisle tell the story of salvation: Star of David—Jesus was born as a Jew; Three Crowns—with the arrival of the Three Kings Jesus was made manifest to the world and, in Christian baptism, one is born priest, prophet, and king; Instruments of the Passion—Christ's suffering for our Salvation; Banner—the Resurrection; Star—Christ is the Light of the World.

In 2003, work was completed on a replica of the renowned Veit Stoss Altar (Polish: Ołtarz Wita Stwosza) of St. Mary's Basilica in Kraków.

Carved by artist Michał Batkiewicz over an eight-year period, this one-third scale copy was commissioned as a tribute to the Galician immigrants who founded the parish in 1893.

The parish also has a nineteenth-century copy of the icon of Our Lady of Częstochowa adorned with jeweled crowns blessed by Pope John Paul II; a reproduction of a crucifix from Limpus, Portugal, a nineteenth-century Pietà from Bavaria, Germany, a hand written altar missal on display, as well as several hundred authenticated relics of saints.
