In Mellingen on the River Ilm southeast of Weimar there were once two castles: one on the Kapellenberg hill and the Heinrichsburg, both of which were probably destroyed during the Saxon Fratricidal War. Both castles, separated by about 1.5 kilometres, were supposed to have been connected by a leather bridge. Especially in the older literature (around 1900) it is posited that this legend is a mythological reference to Edda.
