Edzná means "House of the Itzáes" It is one of the most interesting Mayan cities thanks to the technological advances discovered.
Due to the type of soil, the valley in which it lies, is flooded during the rainy season and maintains high humidity almost all year. To overcome this disadvantage the Mayas developed an advanced system of waterworks: a network of canals draining the valley and the water was led into a lagoon that was transformed into dam through walls, while other channels were used to irrigate the fields.
This led to an optimal level of moisture in the soil for intensive cultivation while channels provided abundant fishing; they were also used as ways of communication and in some cases served as a defense. Their squares had a great drainage system and rainwater reached artificial tanks called “chultunes”.
Edzná had numerous religious, administrative and residential buildings spread over an area of about 25 square kilometers. Its architecture has influenced of the Puuc, Chenes and Petén style.
The earliest evidence of occupation in this settlement dating back to 400 BC., when a community was established in the valley and developed as principally activity the agriculture, constituting a well-organized society.
