Hainburg
an der Donau.
Wine TastingHiking
Hainburg is a remarkably well-preserved medieval town on the Danube, marking Austria's eastern border with Slovakia. The town features impressive medieval fortifications including walls, towers, and three historic gates that still define the old town. The castle ruins on Schlossberg hill overlook both the Danube and the surrounding plains. Hainburg's strategic border position shaped its history as a defensive stronghold. Today, the town combines medieval atmosphere with natural beauty, surrounded by the Danube Auen National Park wetlands and the Braunsberg nature reserve. The combination of medieval architecture, border location, and pristine nature creates a unique destination for history and nature enthusiasts.
