The Heimenburg castle ruins on the Schlossberg above Hainburg are among the oldest castle complexes in Austria and look back on a history of almost a thousand years. Between the preserved walls, the former significance of the fortress can still be well imagined. In addition, the exposed location offers a magnificent view over Hainburg, the Danube and the surrounding landscape. 🏰🌄

The Götzenturm (Idol Tower) is a medieval defensive tower on the city wall of Hainburg an der Donau, built in the 13th century as part of the city's fortifications. Often referred to today as the "Water Tower," the building originally had nothing to do with water supply – the name was erroneously coined by locals. The tower was part of the fortifications for the city's defense and, with its solid construction, small window openings, and elevated position, offers a good overview of the Danube and the surrounding area. For cyclists on the Danube Cycle Path or passing through Hainburg's old town, the Götzenturm is a striking landmark and an impressive relic from the time when Hainburg was one of Austria's most powerful fortress towns.

Orth Castle is one of the oldest surviving castles in the region and has a long history dating back to the Middle Ages. The castle was first mentioned in the 12th century and was originally a medieval moated castle. In the 16th century, the castle was converted into a Renaissance palace. Over the centuries, it served various noble families and was later taken over by the municipality. Today, it is a listed building, is an important part of Lower Austria's cultural heritage and is particularly known as the Danube-Auen National Park Center. The castle houses the national park's visitor center, which is dedicated to the unique flora and fauna of this protected floodplain landscape. Orth Castle is located right in the heart of the Danube-Auen National Park, one of the last great floodplain landscapes in Central Europe. It combines historical architecture with modern environmental education. An ideal place to learn more about the fascinating floodplain landscape and its importance for nature conservation while enjoying the beauty of the surroundings.

Petronell Castle was first built in the 11th century. The four-winged castle complex that still exists today was planned by Dominio Carlone (around 1615 - 1679) on behalf of the Abensperg-Traun family. The castle is decorated with frescoes by Caprovo Tencalla. The castle was owned by the Abensperg and Traun families for 17 generations and was sold to a private investor in 2006 and can therefore only be viewed from the outside.

Water tower (Idol tower), Hainburg a.d. Donau The Idol farm in the north-eastern part of the town was traditionally owned by the so-called Lords of Röthelstein, named after the extensive castle and fortification complex located about 2 km downstream on a steep rock massif above the Danube. The Röthelstein castle was founded around the middle of the 12th century by the Sonnberger family, who originally lived in the central castle on the Schlossberg. In the 13th century they were among the most powerful city ministerials in Hainburg. The Idol farm served them primarily as a power base in the town, as well as for managing their huge properties and fishing grounds in the Danube floodplains opposite, and undoubtedly also for Danube trade. The only, but extremely monumental, remnant of the Idol farm is the one built in the first half or shortly after the middle of the 13th century. The octagonal Götzenturm, built in 1444, forms the north-east corner of the city fortifications. Its first and second floors were used exclusively for military purposes (mainly to cover the nearby harbor area), while the third floor with its late Romanesque double windows undoubtedly served a representative residential function. The adjacent eastern city wall is probably one of the few places in the city fortifications that, like the Vienna and Hungarian gates and the castle's ring wall, had an external defensive gallery from which the attackers could be fought effectively from above. This information was kindly provided by Mr. Mag. Scholz and Mr. MMag. R. Woldron. Many thanks to the Monument Office, the Vienna City and State Archives, the Boltzmann Institute and the Lower Austrian State Archives.
