Archaeologists in Switzerland recently made an unusual discovery while excavating the land around a medieval castle near the German border. The crews unearthed a well-preserved gauntlet that experts believe was forged during the 14th century, which would be unprecedented, officials said in an announcement that described the armor as a “sensational find.”

“At first, Lorena Burkhardt hardly dared to voice her suspicions: This is a sensation in archeology!” reads a translated post shared on Facebook earlier this month by the canton of Zürich. It accompanies a video where Burkhardt, an archeologist leading the excavation, discusses the ancient artifact.

“Never before has such a well-preserved and complete gauntlet from the 14th century appeared in Switzerland,” the post continues. “Who did the gauntlet belong to? Was it newly made in the Kyburg forge or already worn in battle? Cantonal archeology will now investigate such questions.”
