Hardegg Castle, Lower Austria, Thayatal National Park


The 13.3 sq. km (5 sq. mi) Thayatal National Park is located in the northeastern part of Austria in the state of Lower Austria along the country’s border with the Czech Republic.

It is situated directly across the border from the Czech Národní Park Podyjí. Thanks to its steep hillside forests, the national park features one of the most stunning gorge valleys in Austria.

Located in the national park is the town of Hardegg and its historic castle, Burg Hardegg. You can actually walk to Národní Park Podyjí in Czechia from Hardegg by crossing over the bridge that traverses the river Thaya.

The impressive Umlaufberg, the 378 m (1,167 ft) most prominent peak in the national park, is almost surrounded by the river Thaya. It offers its visitor a fantastic view of the surrounding forests and meadows and, on the other hand, it is teeming with life.

Thayatal National Park is home to a diversity of plant and animal species. In fact, despite its small size, the park is home to many endangered species such as the European wildcat and the black stork. This is because the park is situated along a climatic boundary between the Alps to the southwest and the more continental climate to the north.

In the west and on the more shady northern slopes of the park, beech forest communities dominate the landscape. In the eastern part of the park, you can find oak forests, particularly on warm, dry south-facing slopes.

Visitors can also find sycamore elms here in addition to common beech. Other plants found in this part of the park include martagon lily, daphne, sorrel, onion toothroot, and single-flowered pearl grass.

The park is home to many interesting animal species, including:

  • Black Stork & White Stork – The black stork (Ciconia nigra) and the white stork (Ciconia ciconia) are the only species of the stork family (Ciconiidae) found in Europe. Visitors can spot the black stork in the Thayatal, where it lives hidden away in densely forested areas.
  • Green Lizard – The eastern green lizard (Lacerta viridis) is a large European lizard species with a green base coloration. Green lizards prefer sun-warmed, south-facing slopes and a mix of both open and forested habitats. For example, drier forest edges, grassy vineyards, semi-arid grassland are particularly suitable habitats for the eastern green lizard.
  • Turk's Cap Lily – The Turk's cap lily (Lilium martagon) is a plant species that’s found throughout Thayatal National Park. Due to its strikingly shaped flowers and large stature, it is considered one of the most popular lilies that’s native to Europe.
  • White Helleborine – The white helleborine (Cephalanthera damasonium) was voted Orchid of the Year 2017. It is part of the orchid family (Orchidaceae). Compared to many other native orchids, the white helleborine is still common. The stunning orchid inhabits a wide range of forests in the park and it can also be found in bushes on semi-arid and arid grassland.

Human History

The area in and around what is now Thayatal National Park has been home to humans for thousands of years.

Archaeological evidence suggests that humans have lived in what is now Lower Austria since at least the early Stone Age, if not earlier. The region was also once part of a Celtic kingdom before it became part of the Roman Empire as a province called Noricum.

After the fall of the Roman Empire, the region was primarily home to a Germanic people called the Bavarii, who lived throughout the region until the Frankish Empire took control around the start of the ninth century.

From about the tenth to twelfth centuries, the region was ruled as part of the Margraviate of Austria. During this time, around 1145, Hardegg Castle was built in what’s now the nearby town of Hardegg. The castle was later acquired by the Counts of Plain and the town around the castle was established shortly thereafter.

However, the region saw substantial fighting during the Hussite Wars in the 1400s due to its proximity to the Kingdom of Bohemia. The region was later bequeathed to the archdukes of Austria.

During his rule, Maximilian I, Holy Roman Emperor, gave Hardegg to the Prueschenk family and gave them the title of Counts of Hardegg. Nevertheless, the castle itself started to decay and it fell into a state of disrepair until it was rebuilt in the nineteenth century.

After World War I, the region that is now Thayatal National Park was located along the border of the First Austrian Republic and the newly formed Czechoslovakia. During World War II, the entirety of the area on both the contemporary Czech and Austrian sides of the border was part of the Nazi-controlled Reichsgau Niederdonau.

A decade after the Second World War ended, the land to the south of what is now the Czech Republic became part of the independent sovereign state of Austria.

In 1984, plans surfaced that a power plant was to be built on the Czech side of the Thaya. Citizens' initiatives and protests by the city of Hardegg successfully prevented this project.

In 1988 and 1991, the areas to the north and south of the Thaya River were declared nature reserves.

The area along the river in Lower Austria was first placed under nature protection by the state government in 1991 though it didn’t achieve national park status until 1997. Podyjí National Park in the South Moravian Region of Czechia was created a few years later in 1988.
