For a fascinating history lesson, visit the crumbling ruins of Kuenringerburg and try to imagine how it looked in its heyday.
Situated in Durnstein, this once-important structure is well worth including on your itinerary. But you'll find tons more to discover in this area. Gottweig Abbey, Winzer Krems, and Maria Langegg Wallfahrtskirche aren't too far from Kuenringerburg.
