Fürstenberg Castle

Fürstenberg is a medieval castle on elevated terrain above the Rhine near Oberdiebach, featuring a circular keep and preserved curtain wall sections. The ruins display later additions including reinforced towers and strengthened defensive elements that enhanced the structure over time.

Construction began in 1219 under Archbishop Engelbert I of Cologne to protect territorial holdings and collect tolls from river traffic. The fortress underwent expansion in the 16th century with additional defensive systems added to strengthen its position.

For local residents, the castle serves as a visible reminder of medieval authority that can be recognized from the Rhine. The structure shows how fortifications controlled river trade and settlements, shaping the lives of merchants and travelers.

The site is privately owned and closed to public access, but the Rhine valley provides several viewpoints from riverside paths and roads. Photography is possible from the road toward Rheindiebach or from river cruises passing through the area.

The castle was protected by an exceptionally wide and deep moat with a drawbridge positioned on the mountain side of the structure. This defensive system was more sophisticated than many comparable fortifications of that era.
