Four niches surround Saint Cyril and Saint Methodius, each dedicated to a different saint significant to the Polish people: Saint Hedwig, Patron Saint of Silesia; Saint Hyacinth, Apostle of the North; Saint Stanislaus, Martyred Bishop of Kraków; Saint John Paul the Great.
Occupying a unique niche of her own is Our Lady of Częstochowa, Queen and Protector of Poland.
