The Marksburg (German pronunciation: [ˈmaʁksbʊʁk]) is a castle above the town of Braubach in Rhineland-Palatinate, Germany. It is one of the principal sites of the Rhine Gorge UNESCO World Heritage Site. The fortress was used for protection rather than as a residence for royal families. It has a striking example of a bergfried designed as a butter-churn tower. Of the 40 hill castles between Bingen am Rhein and Koblenz the Marksburg was one of only two which had never been destroyed (the other being Maus Castle) and at least the only one that had never fallen into disrepair.
