Chichen Itza archeological zone, one of the new Seven Wonders of the World and located on Mexico's Yucatan peninsula, is spectacular to see at any time of year. But for a really special show, visit Chichen itza during the spring and fall equinox, at these times thousands of visitors from around the world, arrive to view the stunning show of light and shadows, where it appears that a shadowed serpent makes its way down the steps of the great pyramid just at the time of the equinox. This amazing spectacle happened yesterday for those lucky individuals in attendance.
The sunlight casts a serpent-like shape on the north staircase of the four-sided pyramid. The angle of the sun shining off the northwest corner projects a shadow on the north staircase. The mathematically precise cast of light lasts for approximately 5 hours. The sun plays on the stone in a way that makes it appear that the body of a snake is descending the stairs to join the sculpture of a snake's head that lies at the bottom.
The ancient Mayans believed the light came from the heavens and passed through the Sacred Cenote, making all their land fertile. Mayan ruins are found in many locations in Mexico and Central America, but Chichen Itza remains one the most famous and significant of them. It was considered to be the center of the Mayan civilization and one of its greatest architectural achievements.
Many mysteries remain about the Mayans and how they accomplished their engineering, architectural and astronomical feats. Tourists, historians, astronomers and scientists from all over the world gather to marvel at the equinox celebrations and the remarkable display of wonder and science of these Mayan ruins.
