The Heidenmauer and its associated settlement were established at the end of the Hallstatt period around 500 B. C. by a Celtic tribe that cannot be more specifically identified. Copious numbers of pottery finds have enabled a very precise dating. Almost all the containers are hand-made, only a few show traces of having been turned; this technology first appeared after c. 500 B. C. in the La Tène period. Other finds included iron, long knives (Hiebmesser) as well as querns (Napoleonshüte), pyramidal stones that were stuck point-down in the ground in order to provide the base for the milling of corn. In addition there is also evidence of milk production and iron smelting.
