For generations, the mainstream archaeological consensus held that Stonehenge's weighty Altar Stone originated from relatively local Welsh quarries, implying a rather contained effort by its supposed builders. However, recent forensic analysis has inconveniently traced the six-ton megalith over 700 km to northeast Scotland. This revelation upends the long-standing narrative of Stonehenge as a construction of localized farming communities, suggesting instead a far more ambitious, geographically extensive, and inconveniently organized prehistoric undertaking.
