Experts have discovered a third structure within the Kukulkan pyramid in eastern Mexico, revealing that it was built like a “Russian nesting doll”, experts said on Wednesday. A 10m tall pyramid was found within another 20m structure, which itself is enveloped by the 30m exterior visible at the Mayan archeological complex known as Chichen Itza in Yucatan state. The smallest pyramid was built between the years 550 and 800, engineers and anthropologists said. The middle structure had already been discovered in the 1930s and dates back to the years 800-1,000 while the largest one was finished between 1050-1300. The discovery suggests that the pyramid, also known as El Castillo (The Castle), was built in three phases.
Archaeologists have discovered what may be the original structure built at the pyramid of Kukulkan at the Mayan ruins of Chichen Itza, experts said Wednesday. Last year, archaeologists using electrical imagining techniques found that the pyramid, which is also known as El Castillo, was built atop a subterranean river, or a cenote. Archaeologists have long known that a smaller pyramid is encapsulated underneath the visible temple. Researchers said Wednesday that they had detected an even smaller structure inside the other two structures. Using what is called tri-dimensional electric resistivity tomography, or "ERT-3D," they found a 10-meter (yard) tall structure within the 20-meter (yard) tall 'intermediate' pyramid that was covered over by the last construction stage, perhaps around 900 A.D.
