More than 400 ceramic effigies of cocoa beans have been excavated from the ruins of Balberta, a count that says something essential about what this city valued and what made it rich. Situated on a flat coastal plain in Guatemala's Escuintla Department, just 34 meters above sea level and 19 kilometers from the Pacific shore, Balberta was a major Early Classic Maya trading center that reached its peak between AD 200 and 400. It is the only known site on the Guatemalan Pacific coast where Early Classic architecture stands exposed -- not buried beneath later construction. The city rose fast, grew powerful, and then vanished. Around AD 400, Balberta was suddenly abandoned, its population apparently shifting to a new center called Montana, just kilometers away. The reason was not war or disaster but something more calculated: a change in the foreign policy of Teotihuacan.
