Journey to the heart of Viking civilization in Norway, where ancient Norse navigators once used mysterious sunstone crystals to traverse the treacherous northern seas. This rugged Scandinavian landscape holds secrets of maritime technology that enabled Vikings to reach North America centuries before Columbus, making it a fascinating destination for history enthusiasts and adventure seekers alike.
Norway is a Nordic country occupying the western and northernmost portions of the Scandinavian Peninsula, with a total area of 385,207 square kilometres and an extensive coastline facing the North Sea, Norwegian Sea, and Barents Sea. The unified kingdom was established in 872 as a merger of petty kingdoms and served as the homeland of the Vikings during their maritime expansion from the 8th to 11th centuries. Josh Gates investigated Norway's Viking heritage in Expedition Unknown, focusing on the legendary sunstone — a navigation crystal Vikings may have used to locate the sun during overcast conditions. The episode took Gates 1,000 feet underground into a deserted mine to test whether certain crystals could have enabled the Norse seafarers to navigate the treacherous northern waters and reach destinations as distant as North America.

Gates investigates Viking sunstone navigation technology (Expedition Unknown S01E06)
The Viking sunstone has fascinated historians and archaeologists for decades, particularly after references to a mysterious navigation aid appeared in medieval Icelandic sagas. Mainstream researchers have proposed that Vikings may have used calcite crystals or other light-polarizing minerals to detect the sun's position through overcast skies — a technique that would have been crucial for navigating the North Atlantic's notoriously cloudy conditions. Laboratory experiments have demonstrated that certain crystals can indeed reveal polarization patterns in skylight, potentially allowing navigators to determine solar azimuth even without direct visibility of the sun.
The challenge lies in archaeological confirmation: while a calcite crystal was discovered aboard a 16th-century English shipwreck, no definitively identified sunstone has been recovered from a confirmed Viking-age vessel. Some researchers argue that Vikings' documented navigational success — reaching Iceland, Greenland, and North America — strongly suggests they possessed sophisticated techniques beyond simple coastal piloting and dead reckoning. Others maintain that experienced seafarers could have relied on knowledge of ocean swells, wildlife patterns, and stellar navigation during clear nights.
Gates' investigation examined the geological basis for the sunstone legend by visiting Norwegian mining sites where Vikings could have sourced suitable crystals. The episode consulted with experts on Viking navigation and optical mineralogy to test whether the technology was feasible with materials available to Norse seafarers. Rather than claiming definitive proof, the episode demonstrated that the sunstone theory remains plausible based on both historical references and modern optical experiments.
Norway's role as the Viking homeland makes it the natural starting point for investigating Norse maritime technology. The country's extensive coastline — facing multiple seas and stretching into the Arctic — presented both opportunities and challenges that shaped Viking shipbuilding and navigation techniques. While the sunstone mystery remains unsolved, Gates' exploration highlighted how environmental constraints may have driven genuine technological innovation among medieval seafarers.
The unified kingdom of Norway has existed continuously for over 1,150 years since its establishment in 872.
Norway maintains the world's largest sovereign wealth fund, valued at approximately US$2.1 trillion.
On a per-capita basis, Norway is the world's largest producer of oil and natural gas outside of the Middle East.
The country claims Antarctic territories including Peter I Island and Queen Maud Land, in addition to the Arctic archipelago Svalbard.
Norway is highly accessible to international visitors, with modern infrastructure throughout the country and Oslo serving as the primary entry point. Specific Viking historical sites, museums, and reconstructed settlements are scattered across the country, particularly along the western and southern coasts. For visitors interested in Viking heritage, institutions like the Viking Ship Museum in Oslo and archaeological sites in western Norway offer well-preserved artifacts and educational exhibits.
Oslo, Norway's capital and largest city, serves as the primary gateway for most international visitors.
Summer (June through August) offers the longest daylight hours and mildest weather for exploring Norway's coastal and mountainous regions, though this is also peak tourist season. Late spring and early autumn provide fewer crowds while still maintaining reasonable weather for outdoor activities.
Denmark
Denmark was politically united with Norway from 1537 to 1814 and shares deep Viking-age cultural connections, making it part of the broader Norse maritime heritage Gates has explored.
Scotland
Scotland was significantly impacted by Viking settlement and Norse maritime expansion, with archaeological evidence of Norwegian Viking influence throughout the Scottish islands.
England
England was a major target of Viking raids and settlement, particularly by Norwegian and Danish Vikings, and features extensively in the historical record of Norse maritime activity that Gates has investigated.
Best time to visit: Visit during late spring to early fall (May-September) when weather conditions are most favorable for exploring mining sites and outdoor historical locations.
Travel tip: Bring warm, waterproof clothing even in summer as Norwegian mining sites and coastal areas can be cold and damp year-round.
