A team of archaeologists have unearthed a rare sword that dates back to the time of the Kalmar War.

Archaeologists from the Arkeologerna have been excavating a stone cellar in the town of Kalmar, which is in Sweden.

The team of researchers theorize that the cellar may have been apart of a medieval farm, which according to ancient contemporary texts, suggests that it may have once been owned by Gotskalk Hulskede in the year 1368.

The farm appears to have been burned down in the summer of 1611 during the time of Kalmar War, according to Heritage Daily.

During the excavation at the site, the team of archaeologists discovered a rare Danish sward, which could show an evolution from a medieval sword to one of a more modern design that would come to dominate the 17th century battlefield.

In a statement issued by Arkeologerna: “At the time of the Kalmar War, the European armies were in a turning point – the military revolution – where new tactics and weapon systems were being tested. This find fits well into the arsenal of the time.”
