In a peat bog in Poland, not far from the border with Ukraine, a knight’s sword has been found preserved in a peat bog, International Business Times reports.

The sword dates back to the 14th century, and though the organic material that would have wrapped the hilt did not survive, the sword itself is remarkably intact. It would have been very light. Engraved on the sword is the sign of a cross, which would have been a trademark of sorts from the manufacturer.

After being cleaned, the sword will go to a local museum, Stanisław Staszic Museum in Hrubieszów. Local experts believe that a knight may have dropped the sword in the bog—or that he may have been sucked in himself. They’re planning on conducting a more extensive excavation to see if there’s anything else to discover in the spot.
