The outlying centre of Pielsbach over on the other side of the Glan was until the 14th century a self-administering municipality. It stretches up its namesake brook, the Pielsbach, back from the Glan, into which the brook empties. Old records show that it was named "Pelsbach" or "Pilsbach" (1364), "Pelesbach" (1381), "Pilßbach" (1433) and then finally Pielsbach (1585). The like-named brook crops up in records from the years 1585 to 1588, likewise with the name Pielsbach. Writers Dolch and Greule trace the name back to a pre-Germanic waterway name, "Pelisa", to which the placename ending "—bach" was added in German/Germanic times.
