Stories about the karst lake

A mermaid or ghosts are said to live in the lake, there is also talk of the Mummelsee king. According to an ancient story, even the entrance to the center of the earth is said to be in it. The name Mummelsee most likely comes from the water roses that used to be here and that were popularly called Mummel.
