The fortress was founded by the Freising bishops, and it belonged to them for more than two centuries, performing exclusively defensive functions. Each owner tried to leave something of their own in the architecture, the changes were not always useful. Among the most significant changes is the drawbridge, as well as the paintings of the chapel. In the 17th century, the building was slightly modified, it began to look like a noble estate. It burned down some time ago, and was abandoned for a long time.
