Historically, it cannot be stated exactly who first built a castle on the ridge near Bernkastel. What is certain, however, is that Provost Adalbero was the owner of the Bernkastel Castle mentioned in 993.
Boemund I ruled from 1268 to 1299. He provided large funds to provide the castle with magnificent columns, beautiful chambers, strong walls, towers and strong parapets. He wanted to help the place gain a higher reputation by obtaining city rights for Bernkastel from the then German Emperor Rudolf von Habsburg. This is how Bernkastel was raised to the status of a town in 1291.
During the reign of Elector Boemund II, there is also a legend as to how today's world-famous Doctor wine got its name: thanks to the healing properties of the said wine, the Elector was able to be freed from his suffering from a serious illness, which the most expensive medicine could not overcome until now . This is how the Bernkasteler Doctor wine got its name. The famous vineyard is still the most expensive in the world.
Through power, greed, hatred and war, the castle has been destroyed three times over the years, most recently in 1692 when a conflagration burned down the castle in the 17th century. It was given the name "Landshut Castle Ruins", the remains of which can still be visited today.
