Our favourite church in Kraków thanks to the gorgeous interior Art Nouveau murals by native son Stanisław Wyspiański, which nicely balance the organic and geometric with unique floral patterns that make this the most colourful place of worship in the city. Wyspiański also made the eight stained-glass windows around 1895, including the controversial and iconic centrepiece, 'God the Father in the Act of Creation.' Dating back to the 13th century, St. Francis' Basilica was the first brick building in the city and is well worth popping in, even for those who could care less for looking at another church.
