Archaeologists just solved a century-old mystery at Cambodia’s Angkor Temple Complex. They unearthed the long-lost torso of a Buddha statue from the Khmer Empire, the medieval Hindu-Buddhist civilization that once exerted influence over much of mainland Southeast Asia.

Archaeologists discovered a torso that unexpectedly matched an iconic Buddha head that had been unearthed more than a century ago. Spanning 402 acres, Angkor is recognized as one of the most significant archaeological sites in Southeast Asia.

Archaeologists in Cambodia are celebrating an unexpected find at the country’s centuries-old Angkor temple complex: the torso of a statue of Buddha that matches a head found nearly a century ago at the same site.
