Skamieniałe Miasto - Stone City (literal translation: ‘city turned into stone’), a nature reserve near the town of Ciężkowice, Poland.

A legendary tale about the rock formations “tells a story about a cruel master who once ruled the local castle and surrounding village. Not only a thief, he was a man with a repulsive disposition who aroused fear and hate in most everyone he met. Consequently, it was no surprise that when his wife died he could not find a suitable willing candidate for marriage. Frustrated, he decided to marry his own daughter and began to prepare a wedding feast. Yet as soon as the ceremony started the whole castle including all the guests and town inhabitants were turned to stone.

Yet another legend describes the degradation of a town into a state where its inhabitants live lives of immorality, promiscuity, and excessive drinking. As a result they were punished and became the rock formations that we can see today.” [x]
