The castle museum provides an insight into the history of the Middle Moselle through historical displays. Worth mentioning is the only collection of all graphics of the course of the Moselle published about 200 years ago. They show typical buildings of individual Moselle villages. Portraits of Trier electors as well as old printed matter from the defunct electoral state bear witness to once glorious times and, along with armour and weapons, lend the museum its imprint. It also houses a memorial to the former Federal President Dr. Heinrich Lübke with guest gifts and personal mementos from all over the world. This represents a special treasure trove for modern-day enthusiasts. The centrepiece is a wall hanging owned by Madame Pompadour, which was given to Heinrich Lübke by the French President.
