Basilica of St Francis

Duck into the dark basilica on a sunny day to admire the artistry of Stanisław Wyspiański, who designed the fantastic art nouveau stained-glass windows. The multicoloured deity in the chancel above the organ loft is a masterpiece. From the transept, you can also enter the Gothic cloister of the Franciscan Monastery to admire the fragments of 15th-century frescoes. Closed to tourists during mass.
