While digging near the site that will host the 2012 Olympics in Weymouth, England, construction crews discovered a mass grave of 51 skeletal remains that predate the Norman conquest of England. It has been determined that they were Vikings caught and executed by the Anglo-Saxons. It is a unique find because it is not very often that definitive evidence is found dating remains to this time period and showing them to be Vikings. It is also extremely uncommon to find mass graves in England. Archaeologist hope to find more details about the lives of the men with further study of the remains.
