When Świnoujście became a port city, its inhabitants began to work on ships, leaving for long cruises. The wives waited for the sailors, who returned exhausted and aged. One of them, Alice, distraught by the appearance of her beloved Christopher, went to the seashore at night and cried. A mysterious voice told her to seek rescue in the windmill behind her, from which the old miller came out. He ordered Alice to come the next day with her husband; then he ordered to cover him with mud, take a bath in the sea and walk on the shore. A week later, he took him to a windmill. After some time, Alice's husband came out of the interior rejuvenated. The windmill was quickly visited by other sailors as well. However, when the old miller died, it turned out that no one knew the secrets of his treatments, and the mechanism of the windmill stopped. Despite this, people thirsty for rejuvenation continued to come – and still come today – to Świnoujście to cover themselves with mud, swim and walk.
