Wawel Cathedral is the most important church in Krakow that was built more than 900 years ago, where many prominent Poles, Polish kings and their families, national heroes and many bishops are buried. In addition to the Cathedral Museum, which is also worth a visit, there is also the giant Zygoment bell. In front of the cathedral there is a statue of the Wawel Dragon (which is a symbol of the city) that breathes real fire.
