St. Mary of Perpetual Help Church in Chicago, inside view [Polish parishes and churches in Chicago]

The unusual feature of the church are three domes located above the main nave and at the intersection with the transept. They create the impression of opening the space inside to infinity. On the pendentives of the three domes there are paintings of the twelve apostles, which illustrates
their role as intermediaries between the Church on earth and the Kingdom in heaven. On the apse wall, the patron saints of Poland are depicted on a golden background imitating mosaic: St. Stanislaus Kostka, St. Kinga, St. John Cantius, St. Adalbert, St. Stanislaw Bishop and Martyr, St. Casimir, St. Hedwig and St. Andrew Bobola. The marble main altar and two wooden side altars
– Blessed Virgin Mary and St. Joseph – are part of the original furnishings of the church (1893).
