| The Fortress (Festung) is built on a rock the height of which amounts to 90 m. Sometimes erroneously called Schloss Garoldseck, the fortress was mentioned as Castrum Caofstein in a document for the first time in 1205. It was enlarged several times. The most important tower, the round and impressive Kaiserturm, was built from 1518-22. Several times in its history, the fortress was used as a prison. Today it is famous for its large organ (Heldenorgel). |
