 In 1535, the lordly building was already in ruins and the Counts of Ingelheim, who already had their seat at nearby Mespelbrunn Castle, then had an estate built there, which was named Höllenhof after the nearby "Höllschlucht" (a gorge).About 1700 came the first hammerworks, driven by a mill, which took its name, Höllhammer, from the estate.The hammerworks, which in 1795 had been taken over by Georg Ludwig Rexroth, was said in the early 19th century to be “the first and most productive hammerworks” in the Principality of Aschaffenburg.
