Imagine walking along a riverbed and spotting something metallic poking out of the mud—only to realize you're looking at a weapon carried by a warrior ten centuries ago.
That is exactly what happened to Mirosław Tucholski near the town of Wronki in western Poland. Tucholski spotted an exceptionally preserved medieval sword resting in the Warta River, carefully recovered it, and immediately notified local authorities. The Wronki Regional Museum has already called the find "sensational," and an initial look by archaeologist Ryszard Pietrzak confirms it: the weapon is the real deal, dating back to the early medieval period.

into the Warta River as part of an act of worship?
We may never know."

How the sword ended up at the bottom of the river is the ultimate mystery. It might have slipped from the hands of a soldier in the heat of battle, or perhaps it was dropped during an accidental river crossing. But researchers aren't ruling out something more intentional—a ritual offering cast into the waters to appease the gods or mark a sacred vow.
Secrets Exposed by Drought
This incredible find highlights a bittersweet reality for modern archaeology: Europe’s shifting climate. Severe drought conditions across Poland have caused river and lake levels to plunge. While falling water levels act as a time machine—revealing long-hidden treasures like this sword—they also pose a massive threat. Artifacts that stayed perfectly preserved for centuries in stable, oxygen-deprived mud are suddenly exposed to air and rapid decay.
Thankfully, the Wronki sword was secured just in time. In line with Polish heritage laws, the find was logged with the Wielkopolska Voivodeship Monuments Conservation Authority. Wronki's mayor, Rafał Zimny, stepped in with financial backing to fund the next crucial steps: preservation and scientific research.
The weapon is now headed to the experts at Nicolaus Copernicus University in Toruń for professional restoration and high-tech analysis. Once the conservation team finishes their work, the goal is to bring the sword back home to be displayed at the Wronki Regional Museum.
A Growing Underwater Armory
This isn't an isolated stroke of luck. Polish waterways have been yielding an incredible amount of medieval history lately, largely due to shifting waters and dredging projects.
In 2025, a fisherman pulled a 10th-century medieval sword out of the Vistula River near Warsaw's Tarchomin district—a weapon experts suspect belonged to a Viking warrior or a high-ranking local noble.
In 2024, another early medieval blade was uncovered during routine river dredging.
At Lake Lednica, archaeologists have slowly unearthed one of Poland's largest submerged military collections. They have found nearly 300 weapons, including axes, spears, and swords linked directly to the historic reigns of Mieszko I and Bolesław the Brave.
Whether these relics ended up underwater through fierce battles, accidental losses along ancient trade routes, or sacred pagan rituals, they are fundamentally changing what we know about early medieval Europe. For Wronki, this newly discovered sword is bound to become the center of future scientific studies, local educational programs, and a massive draw for history-loving tourists.
