Chichen-Itza, now included as one of the new 7 wonders of the world; the Kukulcán Pyramid, is located in the Peninsula of Yucatan, in the Yucatan State; Mexico. The Maya are probably the best-known of the classical civilizations of Mesoamerica.
The Maya developed astronomy, calendrical systems and hieroglyphic writing. The Maya were noted as well for elaborate and highly decorated ceremonial architecture, including temple-pyramids, palaces and observatories, all built without metal tools. The construction of the Kukulcán Pyramid at Chichén Itzá was planned so that each Vernal Equinox the setting sun would cast a shadow of a serpent writhing down the steps of the pyramid.
The Temple of the Warriors are awe inspiring ruins on the complex. A massive temple structure, surrounded by hundreds of columns is carved with reliefs.
The Observatory shows the interest of the Maya in the annual travels of the sun across the sky and is displayed in many structures at Chichén Itzá.
