Limburg an der Haardt. The oldest established building on the later "Linthberg" is a Celtic settlement. In the 9th century a castle was built by the Gaugrafen from the Salier family, who resided in Worms, which dominated the entrance to the Isenachtal. How the castle looked out is largely unknown. Conrad II, the later King and Emperor, will have spent part of his childhood and youth here.
