 In 1834, the then "Amtsbürgermeister" Sohns bought the former state scrivener's office at Castle Lichtenberg at auction to have a school set up inside it for schoolchildren from Burglichtenberg, Thallichtenberg and Ruthweiler.Of the villages of the "Burgfrieden", the village of Bistert had now ceased to exist, while Körborn and the Frohnbacherhof now lay in the Kingdom of Bavaria and thus, fitted into another school framework.After Thallichtenberg got its own schoolhouse in 1845, the school at the castle only served schoolchildren from Burglichtenberg and Ruthweiler.
