El Castillo - The Castle - Temple of Kukulkan
There are many tunnels beneath the surface of the planet placed there for different reasons. We are more often drawn to 'what lies below' in Egypt - but the discovery of a tunnel below the pyramid of Kukulkan is part of the Maya legacy. It all goes somewhere ... keep digging. Remember ... that which is buried is the past. That which is on the surface of the planet is the present. That which is above is the future.
The Hour of the Zenith - The Legacy of the Snake
Tunnel found under temple in Mexico PhysOrg - May 30, 2011
Researchers found a tunnel under the Temple of the Snake (Feathered Serpent, Quetzalcoatl, Kukulkan) in the pre-Hispanic city of Teotihuacan, about 28 miles northeast of Mexico City. The tunnel had apparently been sealed off around 1,800 years ago. 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. At the end, there are several chambers which could hold the remains of the rulers of that Mesoamerican civilization. If confirmed, it will be one of the most important archaeological discoveries of the 21st century on a global scale.
