Where was the wawel dragon?

The Wawel Dragon, a legendary creature from Polish folklore, is said to have lived in a cave at the foot of Wawel Hill in Kraków, Poland. This cave, known as the Dragon's Den, is a popular tourist attraction today. According to the legend, the dragon terrorized the local inhabitants until it was defeated by a clever young man named Krak, who filled a sheep's skin with sulfur to trick the dragon into consuming it.
