The Marksburg is a fortress above the town of Braubach in Rhineland-Palatinate, Germany. It is the only medieval castle of the Middle Rhine that has never been destroyed. It is one of the principal sites of the UNESCO World Heritage Rhine Gorge. The fortress was used for protection rather than as a residence for royal families.
