Kettenbrunnen or Windenborn
Due to the strong growth of the population, the water of the springs was no longer sufficient. For this reason, a well was dug in a central location of the town. It was probably not considered or it was not known that almost 30 meters had to be dug through the limestone layer deposited by the Zechstein sea in the earth age of the Permian. A laborious work with the tools of the time.
