Prüm Abbey
In 1762, the elector of Trier (as procurator of Prüm Abbey) enfeoffed Josef Franz von Zandt zu Merl with Lissingen. A few years later, in 1780, as an Imperial Knight of the Holy Roman Empire, the latter became "Freiherr" of Lissingen, a small autonomous territory. Lissingen retained this status until the abolition of the Feudal system, and the castle was greatly extended, in particular by the addition of a much larger tithe barn and stables.
