Excavated in 2005, Chacchoben (pronounced cha-cho-ben) is an ancient city that was a contemporary of Kohunlich and the most important trading partner with Guatemala north of the Bacalar Lagoon area. Several newly unearthed buildings are still in good condition. The lofty Templo Uno, the site's main temple, was dedicated to the Mayan sun god Itzamná, and once held a royal tomb. (When archaeologists found it, though, it had already been looted.) Most of the site was built around AD 200, in the Petén style of the early classic period, although the city could have been inhabited as early as 200 BC. It's thought that inhabitants made their living growing cotton and extracting chewing gum and copal resin from the trees.
