Roman history, more recent local history and activities on the water highlight different sides of Zwentendorf an der Donau. The House of History covers everything from excavations at the Roman fort to events of the present day; church architecture, the Danube Cycle Path and swimming spots round out the themes. During your stay, you can tailor the balance of culture, cycling and swimming to your interests.
Roman fort and local history
Since 2021, the archaeological site of the Roman fort of Asturis in the municipality of Zwentendorf has been part of the UNESCO Danube Limes World Heritage Site; it is also a listed monument.
The House of History Zwentendorf – ASTURIS Roman Museum presents excavations of the Roman fort using models, photographs and finds. The exhibition also covers everything from Roman excavations and industrialisation, including the powder factory and nuclear power plant, to events of the present day. This makes the exhibition interesting for travellers who do not want to focus exclusively on Roman times. Asturis as an archaeological site and the museum exhibition offer two different perspectives: the protected archaeological heritage in the municipality and the presentation of the excavations.
The Zwentendorf nuclear power plant never went into operation and never generated electricity from nuclear energy. EVN’s visitor information dated 26 June 2026 lists guided tours that allow visitors to enter rooms in the facility. Before making plans, check whether a suitable tour date is available.
Churches with distinct architectural histories
Zwentendorf Parish Church was originally an early Gothic fortified church and was later converted into a Gothic church with a coffered ceiling and pointed-arch windows. Its architectural history can therefore be read as a transition from an original fortified church to a later Gothic design; the ceiling and windows are specific features of this later phase.
The pilgrimage church of Maria Ponsee originated as a 12th-century chapel in the municipality. From 1716 to 1726, it was enlarged and remodelled in the Baroque style to plans by Jacob Prandtauer. Comparing the two churches, the focus at Zwentendorf is on the conversion of an early Gothic fortified church, while at Maria Ponsee it is on the enlargement and Baroque remodelling of a site that began as an older chapel.
Swimming and cycling
The Danube swimming area, a natural bathing beach, is right in the centre of Zwentendorf. There is a beach volleyball court right next to it. Before visiting, check whether it is currently open for use, as seasonal conditions may vary.
In Dürnrohr, within the municipality, you’ll find the “Bagger”: a bathing pond in a gravel pit for swimming and summer leisure activities. The difference is clear: in Zwentendorf, you’ll find a natural bathing beach in the centre of town; in Dürnrohr, a bathing pond in a gravel pit. Before visiting, check whether both swimming spots are currently open for use, as seasonal conditions may vary.
The Danube Cycle Path runs through Zwentendorf. A fast-charging station for e-bikes is available at the Donauhof on Pappelallee. If you rely on the charging station, check its availability in advance.
