Chichén Itzá is possibly the most famous temple city of the Mayas, a pre-Columbian civilization that lived in present day Central America. It was the political and religious center of Maya civilization during the period from A.D. 750 to 1200.

At the city's heart lies the Temple of Kukulkan (pictured)¡ªwhich rises to a height of 79 feet (24 meters). Each of its four sides has 91 steps¡ªone step for each day of the year, with the 365th day represented by the platform on the top.
