Archaeologists have unearthed what may be Europe's largest prehistoric burial mound ahead of excavations beside a highway in the Czech Republic.
The burial mound, known as a barrow, is roughly 620 feet (190 m) long — nearly twice the length of an American football field — about 50 feet (15 m) across at its widest point, and oriented along a northeast-to-southwest axis, according to a translated statement from the University of Hradec Králové (UHK).
