What to know about Brittany burial mounds may hide human-shaped stones as Coëby cemetery mystery deepens

Archaeologists used electrical resistivity mapping to survey two large earthen mounds, TRED30 and TRED31, at the Coëby cemetery in Brittany, France. The results indicate the presence of buried stone structures, which researchers suggest may be human-shaped standing stones similar to Passy-type monuments.
