In 1337, King John of Bohemia, Count of Luxembourg, built the Freudenburg at the foot of the Eiderberg, called Freyding at the time. As part of a castle protection system between Trier and Luxembourg, it served to secure the Trier-Metz military road. As early as 1346, Freudenburg was referred to as a "city" within the framework of an Electoral Trier collective privilege. As a small peasant town, Freudenburg took over central local functions for the surrounding villages. With the purchase of the Burggraviate of Freyding by the Imperial Abbey of St. Maximin, the castle was rebuilt. In the dispute between the abbey and Elector Philipp Christoph von Sötern, the castle was occupied by electoral Trier troops in 1646, destroyed and never rebuilt. With the former spiritual property, the United Hospices were also assigned the ruins in the course of secularization, which they sold to the community in 1861, which had security work carried out in 1908 and 1980.🏰
