Viking Secrets

Dec 201710 sites✓ transcript

Josh Gates embarks on a transatlantic investigation spanning four nations to unravel three enduring Viking mysteries that could reshape our understanding of medieval history. Beginning in Denmark's National Museum and expanding to Iceland, Greenland, and potentially North America, Gates pursues answers to questions that have puzzled archaeologists for generations: What tactical and technological advantages made these Norse warriors so devastatingly effective across Europe for three centuries? Why did the Viking colony in Greenland seemingly vanish after thriving for generations? And most provocatively, could new evidence prove the Vikings reached what is now the United States 500 years before any other European explorers—a discovery that would fundamentally rewrite American history? Gates follows Norse sagas and charts referencing a mysterious settlement called Vinland, examining what he describes as a "previously-lost piece of evidence" that may finally pinpoint where these legendary seafarers made landfall.

Vikings in America

Jan 201812 sites✓ transcript

Josh Gates traces the Vikings' legendary westward expansion across the North Atlantic, starting in their Danish homeland before journeying to Iceland, Greenland, and ultimately North America. The central mystery: did Norse seafarers reach what is now the United States more than 500 years before Columbus? In Denmark, Gates works with archaeologists excavating a Viking king's fortress, revealing sophisticated military engineering and craftsmanship that transcended their reputation as mere raiders. He tests Viking combat techniques at a festival and sails a replica longship to understand their maritime mastery. The expedition then pushes west to Iceland, where Gates meets archaeologists Kevin Smith and Gudmundur Olafsson at a remote cave site, navigating volcanic terrain that the first Viking settlers encountered in 874 CE—a landscape so apocalyptic it may have reinforced their mythology of Ragnarok.
