Roman Ship Replica Stranded: Why Croatia’s Army Raced to Save a 5-Ton Relic
An 18-metre replica of a first-century Roman vessel grounded in Croatia’s Drava River.
A full-scale replica of a first-century Roman ship has been stranded on a sandbank in Croatia’s Drava River due to record-low water levels, forcing the Croatian Army to launch a rescue operation to prevent permanent damage to the vessel.
The Danuvina Alacris, owned by Germany’s University of Erlangen-Nuremberg (FAU), is one of three replica Roman ships used to study ancient maritime trade routes along the Danube and its tributaries. Constructed with European Union funding as part of the Living Danube Limes project, the 18-meter, five-ton vessel was completed in 2022 after an 18-month build. It replicates river craft used by the Romans from the first century AD onward, when waterways like the Danube and Drava served as critical transport routes for troops, goods, and communication across the empire.
Research Mission Grounded by Drought: roman ship replica
The ship’s grounding near Osijek is the latest consequence of an extreme drought affecting Europe’s inland waterways. After three years of research voyages through Austria, Slovakia, and Hungary, the Danuvina Alacris underwent a full overhaul last October. It returned to the water in April to resume its work, only to be halted by the Drava’s shrinking levels, which have reached their lowest point in nearly 200 years.
FAU uses the replica to reconstruct historical navigation techniques and analyze how ancient vessels performed in different conditions. The project aims to deepen understanding of Roman-era boatbuilding and trade networks, which relied entirely on river transport in the absence of developed road systems.
Military Intervention to Save Cultural Heritage
The Croatian Army’s Guards Armored Mechanized Brigade carried out the salvage operation in difficult terrain, working to stabilize the vessel and prevent structural damage. The military described the effort as an example of its capacity to support civilian institutions in emergencies, particularly when cultural artifacts are at risk.
In a statement, the Croatian Armed Forces emphasized the broader significance of the mission:
“This engagement shows that the Croatian Armed Forces, in addition to its basic task, has capabilities that can be made available to civilian institutions in various circumstances. In this case, it is support in the protection of a valuable specimen that serves the research and presentation of ancient cultural heritage.”
The incident underscores the far-reaching impact of Europe’s drought, which has exposed not only stranded vessels but also historical artifacts, including unexploded ordnance from past conflicts, along drying riverbeds.
