If you follow the hiking trail M4 from the Meschede train station, you will reach the Hünenburg on a hilltop above the Ruhr.
These are the remains of a Carolingian rampart. They date back to the time of Charlemagne's Saxon wars.
From the castle, which was surrounded by two ramparts and a moat, there were wide views over the Hennen and Ruhrtal valleys.
The outer ring (Vorburg) had 2.8 hectares, the inner ring - the main castle - was 0.8 hectares in size. Probably the castle dates back to the late 9th or early 10th century. During excavations, finds were made that indicate that the castle must have been inhabited for a longer period of time.
Today, there is a barbecue area at the Hünenburg.
