 Furthermore, archaeological finds in neighbouring municipalities show that people in the area in prehistoric times did not merely stay temporarily.In Gallo-Roman times especially, the area was relatively heavily settled, bearing witness to which are finds from the surrounding area (Giant Horseman of Diedelkopf, several villae rusticae within Thallichtenberg’s limits, the Mithraic monument in Reichweiler).Regional historians have determined that Ruthweiler’s founding date was sometime in the 8th or 9th century, putting it in the time when the Franks were newly settling the land.
