 The distinction between Thallichtenberg and Burglichtenberg became necessary once a new village had arisen within the castle ruins in the 19th century, and then also because for a long while, the seat of a Prussian "Amtsbezirk" was there.Within what are today Thallichtenberg's municipal limits once lay a whole series of villages, most of which vanished even before the Thirty Years' War.In 1371, a village named Berweiler ("Berwilre") was mentioned, which was described in 1588 by Johannes Hoffmann as “"ehemalige Dorfstadt"” (“former village-town”); it might have lain west of Thallichtenberg.
