Kettenbrunnen or Windenborn
Due to the strong growth in the population, the water from the springs was no longer sufficient. For this reason, a well was dug in a central location in the town. It was probably not taken into account, or rather it was not known, that almost 30 meters had to be dug through the limestone layer deposited by the Zechstein Sea in the Permian period. A laborious task with the tools of the time.
