Later that night I headed back to the river under Wawel to find out what was being set up earlier today, and based on the thousands of others that had also rocked up I figured it must be something good! Much like Ljubljana, Krakow also has a famous dragon of its own in Polish Folklore. He lived in a cave under Wawel Hill on the bank of the river and terrorised everyone. One day, according to the legend, a poor cobbler's apprentice accepted the challenge from the King to kill that fucking dragon after several of the King's knights had failed to do so. He stuffed a lamb with sulphur and set it outside the dragon's cave. The dragon ate it and soon became incredibly thirsty. No amount of water could quell his stomach ache, and after swelling up from drinking half of the Vistula river, he exploded hahaha! The apprentice married the King's daughter as promised and they lived happily ever after. Lovely. Anyway, this is part of the Great Dragon Parade which is an annual celebration of that story. I did see a parade earlier in the day in Market Square, and this is the culmination of that - a sound-and-light show including these inflatable, umm, characters, and fireworks and lasers with music. Video of the action here. This was also the reason for the fair I found earlier (where I got lunch).
