The most recent mill along the Mill Hiking Trail was built in 1833 as an oil mill and sawmill. There,  mainly edible oils from rapeseed and linseed were produced in rolling and crushing processes. The  mill building from the nineteenth century and the now dried-up mill race are still to be seen. The  Haghofer oil mill is used today purely as an agricultural property. Only the race, where the rushing  waters once turned the mill wheels, remains as a reminder of the former mill.
