The realm of Maya spread across 1,00,000 sq.miles and raised many vast centers in present day Mexico, Guatemala ,Belize, Honduras and El Salvador. The great Maya civilization to which Rio Azul belonged developed in the period between 250 B.C. to A.D. 250. Rio Azul, the administrative centre which at its peak in the eight century A.D. numbered close to 3,500 and another 1,500 in the north east suburb comprised mostly of noble military families along with their assistants, servers and retainers.
The classic Mayans maintained articulately controlled landscapes, cultivated fields and water filled canals. They would drain swamps for cultivating crops like beans, corn and probably cacao. The Dams –the largest in the Maya area preserved water for the arid season and several intentionally untouched wastelands that served as buffer zones between rival Maya states. Remnants of digging and cultivating tools dating from eight century have been unearthed.
Rio Azul had a concentration of 350 large buildings. Huge memorial temples standing at 155feet tall were connected by lined walkways to the plush residences of the elite. The 14 storied high pyramid temple that is seen from air amongst the treetops close to the Mexico-Guatemala-Belize border is the standing proof of the vast ruins of Rio Azul considered the highest in the Maya World.
Rio Azul appears to have been abandoned in 535 A.D. mostly due to the civil war period that erupted when older ruling families tried to come into power after Teotihuacans withdrew. The site interior is three square kilometres that has forty one squares, 752 constructions that include a ball court- a game indulged in during the Mayan era, 32 tombs and sixteen alters amongst others. The famed Mayan remnants were systematically and substantially robbed during 1979-1981.
