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. about 1830 some 100 people lived at the höllhammer and the specially built school was attended by up to 30 children. until 1891, production continued. thereafter the lands were converted into an estate. still to be seen are the farmhands’ house with the belltower, the lord's house and the school. the buildings are all used as dwellings, even the old smithies. in the woods is found the rexroth family's old graveyard.
