 The Lords of Leyen, who at first maintained their lordly residence at Koblenz, moved their residence to Blieskastel in 1773.The Münchweiler Tal was only part of the lordly holdings, with the ancestral castle standing on the Moselle and other holdings widely scattered.Between the House of Leyen and Electoral Palatinate there were tight relations, as there also were in the Late Middle Ages between the Lords of Breidenborn and Electoral Palatinate.
