The discovery of a Viking-age fortress in Denmark has shed new light on a network of military sites built by the 10th-century Danish king Harald Bluetooth, according to archaeologists.
Bluetooth — for whom the eponymous digital network technology is named — is credited with building several large, circular fortresses, or "ring forts," around Denmark in the 970s and 980s, as he unified the unruly Viking clans of the region into a centralized kingdom.
