The main alter of the Basilica of St. Francis of Assisi — Austere Gothic architecture on the outside conceals gentle arches and an explosion of colors in the Art Nouveau polychrome wall decorations by Stanisław Wyspiański, the same artist who designed stained glass decoration for eight of the church’s windows. Most of the paintings on the walls of the choir and transept consist of geometrical and vegetal motifs, including common Polish flowers. The windows of the chancel feature the four elements and figures of the Blessed Salomea and St Francis. Dominating the entire church is the monumental stained glass window God the Father - The Creation. The Franciscan Church was one of the favorite prayer sites of the bishop, archbishop and cardinal Karol Wojtyla (later known as Pope John Paul II.) When he served in Krakow, he lived next to the church, just across Franciszkanska street. As Pope, John Paul II visited the basilica twice, in 1979 and 1991.
