Hainburg Castle, also known as Heimenburg, was built by Henry III the Holy Roman Emperor around 1050 to protect the traffic in Danube. It was enlarged in the mid-13th century. The castle was besieged in 1619-1620 by Hungarian army and conquered in 1683 by Ottomans. 

After the new residence was built in 1742 the old castle was left to decay. Today Hainburg castle can freely be visited. A nice castle ruin, giving great views over the medieval town below and the surrounding countryside.

This was an amazing ruins experience. Completely free to visit and to park. It is quite the hike up to see. There is a very long easy path, a shorter steep path and also an off-road walking trail that is for the hiking experts. Beautiful views from the top of the hill.

Probably the best kept free castle site we've ever been to! So well kept, it's just a pity none of the buildings are open. It's such a nice castle, amazing views and great architecture, just a real shame you can't go inside any buildings. I would have happily paid to visit this site in full.

Pleasant sightseeing place with fine lookout to the town. And short but nice walk to the top. Worth a stop on your trip, but maybe not as the final destination.

What an amazing castle. Beautiful views , lots of green , grass and trees. Absolutely worth visiting! Visited on Tuesday and there was nobody else at the time . There also many benches on the way up as well as tables for eating in the castle itself. Great for picnic

Interesting castle ruins in the town of Heinburg. There are 2 ways to climb the mountain - on an asphalt road, but very steep, and on pathway, but longer and quite comfortable for climbing. Free entrance. A beautiful view of the city and the Danube opens from the mountain. There is a small free parking lot under the mountain

Topography of Terror

The Topography of Terror (Topographie des Terrors) is an outdoor and indoor history museum. It is located on Niederkirchnerstrasse, formerly Prinz-Albrecht-Strasse, on the site of buildings which during the Nazi regime from 1933 to 1945 were the headquarters of the Gestapo and the SS, the principal instruments of repression during the Nazi era.

The buildings that housed the Gestapo and SS headquarters were largely destroyed by Allied bombing during early 1945 and the ruins demolished after the war. The boundary between the American and Soviet zones of occupation in Berlin ran along the Prinz-Albrecht-Strasse, so the street soon became a fortified boundary, and the Berlin Wall ran along the south side of the street, renamed Niederkirchnerstrasse, from 1961 to 1989. The wall here was never demolished.
