With the driving force of water, various trades were able to establish themselves in Sinsheim. At the old tannery there was an entire area of the former Stecher tannery. In the building from 1807 there is an old lintel with the symbol of the tanners - a scraper to remove the flesh of the animal skins - and the year 1609. It is a symbol of the long tradition of the tanning trade at this point. Fresh water was needed in the leather processing process.
