Archaeologists have discovered a lost Viking waterway that ran through the Orkney mainland, connecting the North Atlantic with the Scapa Flow, where Vikings are believed to have anchored their longships.
In 2014 archaeologists from the Museum of South East Denmark and Aarhus University discovered the previously unknown Viking fortess at Borgring south of Copenhagen.
When archaeologist Geir Grønnesby dug test pits at 24 different farms in central Norway, he nearly always found thick layers of fire-cracked stones dating from the Viking Age and earlier. Carbon-14 dating of this evidence tells us that ago, Norwegians brewed beer using stones.
