Archaeologists in Switzerland have discovered a stunning Roman shipwreck in Lake Neuchâtel. The site is an unexpected treasure trove of first-century maritime trade. According to Swiss state media, the site was discovered in 2024 when drone photography revealed the site, and excavations were carried out in March 2025 by the Cantonal Archaeological Office (OARC).
The site contains more than 600 artifacts, most notably hundreds of intact ceramic vessels and amphorae used to transport Spanish olive oil. Another unique aspect of this shipwreck site includes the presence of military equipment, such as two complete short swords, indicating that it was a civilian merchant ship with a military escort provided by an army corps. Therefore, this shipwreck site helps fill gaps in knowledge about the common land and sea routes that formed a link between the Mediterranean and the Roman border north of the Alps.
Discovery and excavation of a 2,000-year-old Roman shipwreck in Lake Neuchâtel, Switzerland
Identification of a Roman shipwreck began in 2024 through the use of high-resolution drone imagery that identified the outlines of the ship beneath a layer of lake sediment. Following the aerial discovery, the Cantonal Archaeological Office (OARC) conducted an official excavation of the underwater site in March 2025. The mission was completed by a collaborative team, consisting of professional divers and marine archaeologists, who drew 3D photographic maps of the site and collected fragile archaeological materials.
This “time capsule” has survived intact because it was preserved in specific lake sediments for 2,000 years, preventing the organic and mineral structures from being exposed to oxygen and deteriorating.
Cargo and logistics found in a 2,000-year-old Roman shipwreck
The archaeological site produced an unprecedented number of artifacts (more than 600), the most important of which are hundreds of complete ceramic pieces and amphorae. As written in Swiss state media, scientific analysis of the clay and remains of these ceramic containers has confirmed that they were used to transport olive oil from present-day Baiteca, Spain. The presence of these ceramics in a Swiss lake highlights the wide geographical scope of the Roman logistical system, suggesting that ‘liquid gold’ from the Mediterranean was widely available to residents and soldiers occupying the northernmost regions of the Alps. The large number of ceramics, along with the diversity of their shapes, indicates the existence of a highly organized supply chain, serving the tastes of the Roman settlers and their army stationed in the region.
Military evidence from a 2,000-year-old Roman shipwreck
Among the very important finds at the shipwreck site were military equipment, specifically two complete swords (Roman short swords). According to the Octopus Foundation, these fighters are believed to show that a merchant ship with no military purpose was accompanied by an army corps. During the first century AD, the shipping of valuable goods such as olive oil across vast swaths of territory could be disrupted by internal unrest and piracy.
This discovery proves the actual existence of the Roman government as part of the security apparatus, providing military protection for the commercial interests of the Roman Empire and the means of transporting goods essential to the economy.
Roman shipwreck as a center for Multimodal trade
This shipwreck is one of several links aimed at examining the Roman Empire’s “intermodal” transportation system, in which goods were transported across sea, rivers and land. According to research published in ResearchGate, Lake Neuchâtel played a major role as an inland distribution point connecting the Rhone and Rhine rivers. Researchers studying the placement of goods at this site will eventually provide a clearer picture of the combined use of land and water routes to support the activities of the Roman Empire north of the Alps. This discovery also confirms that the Swiss plateau was not a remote location, but rather a bustling corridor of international trade activity and integrated into the wider Mediterranean economy.
