The value and significance of the Marksburg lie primarily in its complete preservation as a medieval fortification. For many visitors it is the epitome of a medieval castle. Its exposed location on a rocky cone 90 meters above the town of Braubach contributes to this. The imposing fortress with buildings mainly from the 13th to 15th centuries is staggered with a keep, several buildings, kennels and bastions. The typical interior rooms such as the castle kitchen, knights' hall, bower, chapel, armory, wine cellar, battlements and tower rooms are particularly worth seeing. They provide insights into medieval life.

If you should avoid during the holiday season and Saturday and Sunday sometimes 2 bicycles pass each other and the stinging and blackberry thorns hang on the path.

The Marksburg is a 12th-century[1] hilltop castle above the Rhineland-Palatinate town of Braubach am Rhein, from which it got its original name Burg Brubach. It stands on a slate cone at a height of 160 meters and is the only "never destroyed medieval hilltop castle on the Middle Rhine". The plastered quarry stone building was created for the protection and administration of Braubach and initially also served as a customs castle. The castle is a protected cultural monument according to the Monument Protection Act (DSchG) and is entered in the Rhineland-Palatinate list of monuments.[2] Furthermore, it is a protected cultural asset under the Hague Convention and is marked with the blue and white protection symbol. It has also been part of the UNESCO World Heritage Upper Middle Rhine Valley since 2002. (Q: wikipedia)

Old health resort where the tsars, princes and emperors were regulars. Today the place has had its prime. Nevertheless, the old buildings are still beautiful.

The only never-destroyed hilltop castle on the Middle Rhine, dating from the twelfth century. It is worth taking a guided tour. To our knowledge, also possible with a dog (at least it used to be, we had a German Shepherd with us back then). We have been to the castle many times, it was always an experience.
