The ancient Mayan city of Chichen Itza is located in the Yucatan peninsula. The place was the major religious centre of the area. Experts explain the presence of the city on this place by the existence of natural wells (Cenotes) allowing the supply of water in an area where water in a scarce resource.

The main elements of the site consist of the great pyramid of Kukulcan (el Castillo), the astronomic observatory (El Caracol), the field in which people were playing a ball game whose stakes were to have the honor of being sacrificed, the sacred Cenote where sacrifices were done and the one-thousand-columns building.

The great pyramid, 1000 years old, is 30 meters high and has been designed to create certain effects; for example, on the north-east stairs, the clapping echo becomes a sound looking like the flight of the quetzal (local bird). The total number of steps around the pyramid is 365, which indicate a link with the solar calendar.

This pre-Columbian city is a great testimony of Mayan civilization and its people's way of life several millenniums ago.
