Secret Chamber Inside Famous Mayan Temple El Castillo Discovered

Experts say temple is built like 'Russia nesting doll' and reveals secrets about Mayan life. Archaeological experts have unearthed a secret third structure within the most famous Mayan pyramid temple in Mexico, almost a century after the rest of the temple was first explored. The El Castillo pyramid at Chichen Itza, also known as the Temple of Kukulcan, is believed to have been constructed in three stages, with each of its three structures having been built centuries apart. Researchers say the recently discovered smallest pyramid, which is 10m tall, was built at some point between 550 and 800 AD, as the Mayan civilisation reached its peak.
