 The architects and sculptors borrowed ideas from other churches in Poland (Saints Peter and Paul Church, Kraków, Sigismund's Chapel of Wawel Cathedral) and Italy (St. Peter's Basilica, Church of the Gesù).The main entrance is flanked by two large sculptures of Saint Christopher carrying baby Jesus and a skeleton (grim reaper with a cloak and a large scythe) standing on crowns and other symbols of power.Saint Christopher is a protector, but death is still awaits everyone equally and Christians should prepare for it.
