Archaeologists announced Wednesday the discovery of a 2,000 year old tunnel beneath the pre-Hispanic Teotihuacan ruins. A robotic exploration assisted by a video camera determined that the tunnel was man made, stable, had an arched roof, and consisted of a 12 foot corrider. The tunnel was intentionally closed off, between 200 and 250 AD, with 50,000 pieces of jade, stone, shell, pottery, and never before found ceramic beakers. The video footage from the exploration was offered at Mexico's National Institute of Anthropology and History.
Archaelogist Sergio Gomez stated at the video's unveil: "All of the passage, more than 100 meters long was excavated in the rock perfectly, and in some places you can even see the marks of the tools the people of Teotihuacan used to make it." researchers believe the structure once lead to burial chambers.
The entrance to the tunnel was discovered in July beneath the Temple of Quetzacoatl. Ground scans determined the corrider was 40 feet below ground and lead to the central ceremonial area of the ruins suspected to hold the ancient city's early leaders.
Experts are hopeful the tomb will lead to information regarding the social structure and information regarding the monarchs of the Teotihuacan people, a puzzle plauging archaeologists for 100 years.
