The Schöner Brunnen or "Beautiful Fountain" was erected around 1385 but was replaced by a replica in the early 20th century. It has a sixty-two foot spire set into an octagonal pool.
The pool is decorated with statues of philosphers, evangelists and churchfathers. The spire is decorated with statues of Electors, and Jewish and Christian heros.
Set into the railings is the golden ring - turn it three times, your wishes will come true. Or so they say :)
