The history of the castle began in 1094 when the knight Hermannus de Disco was mentioned in a record of the Archbishop of Cologne as the lord of a simple fortification.
In 1383 the castle was besieged by the cities of Aachen and Cologne, as well as by the archbishop Friedrich III von Saarwerden and Duke William I of Guelders and Jülich.
When Gerard van Dyck died without male offspring, the castle was inherited by Johann V von Reifferscheidt, the ancestor of the counts and princes of Salm-Reifferscheid.
The last heiress of the family, Countess Marie Christine Wolff Metternich, turned it over to a foundation to secure the future of the castle.
Count Salentin of Salm-Reifferscheid extended the main building into a four-wing complex; stables, watch rooms, and the brewery were renewed.
