Archaeologists Uncover New Viking Fortress in Denmark

Archaeologists have made a startling discovery in Denmark. They've found a previously unknown Viking fortress in a field that could hold an important piece in Denmark's history.

"This is the first time for more than 60 years that a new Viking ringed fortress has been discovered in Denmark," said Nanna Holm, an archaeologist and curator at the Danish Castle Center, in a news release.

The archaeologists used new, precise laser measurements of the landscape that showed an almost imperceptible mound in a field that had a clear circular outline. Then, they began their measurements.

"Measuring small variations in the magnetic field of the soil enables you to identify old pits or embankments without destroy them," said Soren Sindbaek, one of the researchers. "The technique gave us a surprisingly detailed image of the fortress in no more than a few days. So we knew exactly where to dig the excavation trenches with a few to learning as much as possible about the fortress."

The fortress itself was likely a military facility, and probably the scene of fighting, as well. It likely dates back to the Viking Age, though the archaeologists will have to wait for analysis of burnt timber samples before they can draw any conclusive dates.

"We can't wait to find out whether the fortress dates back to the time of Harald Bluetooth, or whether it was built by a previous king," said Holm. "A military fortification from the Viking Age may shed light on the links between Zealand, ancient Denmark and the Jelling dynasty-as well as teaching us more about the period during which Denmark became Denmark."

Currently, the researchers are hoping to uncover the full story of the fortress's history. They plan to investigate whether any big buildings were built inside the fortress, and perhaps look for other fortresses in the area.
