The castle lords (Burgherren) were the knights of Mülenstein, vassals (Lehnsmänner) of the Rheingrafen family in Grumbach.

Lichtenberg state scribe (Landschreiber) and surveyor, Johannes Hoffmann, wrote in his "Description of the Essweiler Valley in 1595", however, that the castle estate was cleared and cultivated several times by local farmers after its destruction, but the harvests had always failed because of wet and cold summers.

When after a third clearing "a great darkness had come in the middle of the day in summer" and this harvest also failed, they finally gave up and the castle terrain became overgrown over in the following years.

Only the name am alten Schloss and the remains of the neck ditch, which was partly built over by the L372, hinted at what was hidden underneath.

From 1976 onwards, excavations were carried out on the site by students of the University of Maryland under the direction of Professor Higel.

[1] There is a story that if you are on the road between Oberweiler im Tal and Eßweiler in the evening or at night, you may suddenly feel a heavy load on your back that almost pushes you almost to the ground.

According to the legend the hunchbacked dwarf, who lives in the old castle ruins, has hitched a lift on your back and been carried home.

[2] Another legendary phenomenon is the White Lady, who appears to passers-by from the tower of the castle and tries to tempt them to follow her by waving and shouting.
