11. Plain of Jars
The Plain of Jars is a mysterious archaeological site in Laos located on the Xiangkhoang Plateau. About 90 jar locations have been documented with each site including anywhere from one to hundreds of these large stone vessels set into the ground. It has been theorized that the jars, which date back some 2,500 years, may have been used in burial ceremonies, with bodies being left to decompose in them before a later cremation. However, there is still a high degree of uncertainty over the precise purpose of these amazing artifacts.
10. The Headless Vikings of Dorset
Road workers discovered a mass grave in 2009 while they were working near the town of Weymouth in Dorset, England. Archaeologists examined this gruesome find and discovered that there were 51 male skeletons piled in the grave, and that each one had been beheaded. This obvious evidence of a massacre turned out to involve Viking warriors who’d been killed by Anglo Saxons about 1,000 years ago.
