Silesia

An erratic boulder (gray granitoid) with a perimeter of 9.5 meters and a height of 2 meters, known as the "Devil's Stone", located in the Swan Forest. The legend speaks of a treasure buried under it, which resulted in repeated
attempts to dig it up and smash it, including using explosives. The second legend tells of a devil who used a boulder to try to destroy a church in nearby Sobieszowice. As he was carrying it, he was found in the air by dawn and the crowing of a rooster, causing the devil to lose his power and drop the stone.
The boulder is located in a military area.

According to information from 1881, in a field called "Godow" (previously a wooded area), between the villages of Sadowie, Najdziszów and Nowa Wieś, there was to be a stone with "an embossed human foot." It was a large, oval red sandstone. According to local tradition, the footprint was left by the devil, who stood on the boulder. The site was considered haunted. In turn, whoever would put his foot on the marks on the stone would be torn off.
