Hagenberg Castle

Fallbach, Austria

In 1264, castrum Hackenberg is mentioned as a site for document sealing. After the last Hackenberger died, the property passed to Alber Stuchs von Trautmannsdorf in 1382. Christoph Kuenritz bought and converted it into a Renaissance castle in 1543. Plundered in 1620 during the Thirty Years' War, it remained devastated until Sigmund Friedrich von Sinzendorf purchased it in 1650. His nephew, Theodor Reichsgraf von Sinzendorf, remodeled it into a Baroque palace between 1679 and 1677. After Prosper von Sinzendorf's death in 1822, it passed to the Reuß-Köstritz princes but fell into disrepair.

In 1945, it came under Soviet administration as German property, and in 1955, it was returned to Prince Reuß. Artists from the Vienna Group, including Friedensreich Hundertwasser, moved in from 1959. Captain Josef Steiger bought it in 1974, and in 1986, Horst Wächter, Hundertwasser's former assistant, acquired it. The Osmann family took over in 2020, with Horst Wächter remaining for historical research.


The four-story structure features Renaissance geometry and proportions, with medieval foundations. A cosmological mysticism, likely embedded during the 1679 Baroque renovation, is present. The four wings align precisely with the cardinal directions, enclosing a rectangular courtyard. The southern wings retain colorful ceiling frescoes and stucco decorations.

Access is via a short alley in the northeast, crossing a stone bridge into a frescoed entrance hall, leading through the courtyard with an octagonal fountain to a three-bay shell grotto, the 'sala terrena,' decorated with statues, frescoes, shells, and stucco, extending into the garden. The former access extended over the moat to a landscaped area with a Baroque-era artificial lake.

We had an amazing stay at the Schloss Hagenberg this summer. Our family of 18 ppl was able to gather together at the castle to celebrate our small family event. It was better than we expected. The place is magical, with a rich history and atmosphere. It has wonderful nature around, a place to relax and spend lovely days away from the city. The hosts of the castle and staff were incredibly helpful, accommodating and charming people. They helped us with everything, organizing our event, delicious wine and food, service and beautiful rooms. Whole stay at Schloss Hagenberg was charming, the memories to cherish for our lifes. We definitely want to come back, and recommend this place for everyone!

Romantic, privately owned castle with a colorful past, embedded in the fields of the Weinviertel. Nice to hike in summer, smell of straw and hot earth

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.
