Hormuth at Calar Alto. The city of Bad Königshofen is a spa town in the Franconian part of the Grabfeld region in Bavaria, Germany. The earliest known mention of it is from the year 741 CE, but settlements existed much earlier. It still preserves many remains of an impressive star-shaped fortress from the early 18th century.
