Tunnel found under temple in Mexico
- The tunnel had apparently been sealed off around 1,800 years ago.Researchers of Mexico's National University made the finding with a radar device. Closer study revealed a "representation of the underworld," in the words of archaeologist Sergio Gomez Chavez, of Mexico's National Institute of Anthropology and History.Experts found "a route of symbols, whose conclusion appears to lie in the funeral chambers at the end of the tunnel."The structure is 15 yards beneath the ground, and it runs eastwards. It is about 130 yards long.
