The pond owes its existence to groundwater, which is forced to rise through a watertight obstacle. The rising groundwater stirs up fine, light sand, interspersed with white snail shell debris, which was used as writing sand until the beginning of the last century.
Legend of the "Goldig Tor"
(short version according to Meinrad Lienert)
Once upon a time a shepherd boy was tending sheep at the pond. It was a glorious foehn day and the boy lay down on the bank with his eyes heavy with dreams. Suddenly a maiden emerged from the pond up to her shoulders. She lured him with a golden ring on her hand. The boy tried to grab the ring and leaned over the water. Suddenly the maiden took him in both arms and sank with him.
He had barely disappeared when his farmer rushed over, because he had heard his shepherd boy cry out. But he could not see his little shepherd anywhere. Suddenly it shot up like a candle from the golden sand whirlpool in the pond in front of him. He quickly pulled it to the bank. After a while the boy opened his eyes and began to tell what had happened to him: "The water maiden pulled me into an infinite depth. Suddenly I saw a mighty city with a huge golden gate. It just opened wide and a beautiful maiden stepped out. Now the maiden, who was holding me in her arms, opened her arms to greet her friend. At the same moment a whirlpool grabbed me and pulled me up with it. I don't know anything else." The shepherd boy returned to the pond again and again, but he never met the beautiful maiden again. Thanks to his story, however, we now know where the gold flakes in the water come from: they are washed off the golden gate and carried to the surface (content from the information board).
