The site is made up of several buildings: the Ball Court, the Sacred Cenote, the Main Esplanade, the Observatory, the Temple of a Thousand Columns and the Pyramid of Kukulcán or also known as El Castillo, 24 meters high, among others. .

Undoubtedly, it is the latter that drew the most attention due to the phenomenon observed in the change of season. In fact, during the autumn and spring equinoxes, the sun will play sneaking through the windows of the building and project its light in a certain way that will announce the arrival of a new time of the year and reaffirm that the Mayans handled the issue.

The Chichen Itza Pyramid also had the function of serving as a calendar since the total number of steps is 365, as well as the days of the year: 91 steps spread over its 4 steps and one more that leads to the Great Temple.
Regarding the Sacred Cenote, whose measurements are 60 meters in diameter and 35 deep, according to the investigations, objects of great value for the time were found here, for which it was established that both material and human sacrifices were made here, in honor of Chaac Mool, the god of the rains.

For its part, the Ball Game is credited with being the largest in Meso America, as it is 70 meters wide and 169 meters long. Although warlike iconographic expressions were found, their use was also ritual.

Towards the east, there is the Temple of the Jaguars, on whose wall there is a chamber with symbols of community figures such as warriors and priests, as well as icons of animals and aquatic plants.

As for the Observatory, the holes in its walls coincide with the position of the space bodies, so its use was linked to the Mayan calendar.

Finally, the Temple of the Warriors is located on a pyramid-shaped building but is preceded by a set of 200 pilasters known as The Thousand Columns and which represent the warriors. There is also a sculpture of Chac Mool, who is sitting cross-legged.
