Sealed chambers at ancient Aztec site in Mexico City could hold rulers' tombs

The answer to the mystery of leaders' ultimate fate could be revealed behind two doors at the end of a tunnel into a platform at Tenochtitlin's Great Temple

Archaeologists in Mexico have found a passageway and two sealed chambers beneath one of the largest temples of the ancient Aztec capital, raising hopes that excavations will uncover a ruler's tomb beneath the city.

The tunnel, only 18in wide and 5ft high, leads 27ft directly into a circular ceremonial platform at the Great Temple or Templo Mayor complex of Tenochtitlin, the ruined Aztec capital that overlaps with modern Mexico City. At the end of the tunnel the archaeologists found two sealed doors.
