Palenque, Mexico

These extensive Mayan ruins in Chiapas, Mexico, are some of the most impressive in the Americas, and we may be seeing just the tip of the jungle iceberg. Archeologists and historians say that only a small portion of the city has been revealed thus far and as much as 90 percent may still be covered by the surrounding jungle.

Interesting features discovered in Palenque's ruins include an aqueduct that appears to have been designed so that pressurized water is released, much like a modern fountain or shower head.

Many of the buildings of this once-thriving city date back more than a thousand years, and a few structures are thought to be more than two millennia old. Palenque's temples, fronted by steep stairs, are unmistakably Mayan, but other structures, built in different eras, have more unusual traits.
