Frankenburg (Palatinate)
The Frankenburg is a natural monument with the ruins of a rock castle in the county of Südliche Weinstraße in the German state of Rhineland-Palatinate. It lies above the Modenbach valley on a rocky outcrop of the Frankenberg called the Frankenfelsen and was built to guard the road opposite Meistersel Castle.
Today, all that remains of the Frankenburg are a few wall remnants and manmade traces on the rock. The rocky outcrop on the Frankenberg lies at a height of 545 metres above sea level.
