Guayabo National Monument

The biggest and the most important archeological settings in Costa Rica, placed on the foot of Turrialba volcanoe. Since 1973 it has been a national monument. The main architectural features are: cobble-paved causeways and streets, terraced stairways, rataining walls, bridges, mounds used as foundations for housing, cisterns, rectangular structures where water from the aqueducts was stored. Human occupation of that site apparently dates back to 1.000 B.C., although the Indian chiefdom reached its peak around 300-700 A.D. It`s all surrounded by forests, full of Montezuma oropendolas, which characteristic nests are hung from the highest trees.
