"Archaeologists have excavated giant stone spheres in the Diquís Delta of Costa
Rica.
Stone spheres are found on the small island of Isla del Caño and the Diquís
Delta, where over 300 stone Petrospheres have been previously identified from
the Diquís culture.
The Diquís culture emerged in the Valley of the Rio Grande de Térraba, where
they established complex social, economic, and political systems to govern
their society.
During the Chiriquí Period between AD 800 – 1500, many settlements grew into
large communities around the alluvial lands of the Térraba River and its main
tributaries, constructing large structures using round-edged boulders, paved
areas, burial sites, and circular or rectangular mounds with stone walls.
The Diquís reached an apex of cultural development during this period, with
Diquís artisans creating elaborate ceramic, bone, and gold objects, and
sculpturing stone spheres in important zones within the settlements. Stone
spheres were also placed in alignments in public plazas, or along the approach
to the dwellings of the ruling elite or chieftains.
Archaeologists from the Instituto Nacional de Antropología e Historia (INAH)
and the National Museum of Costa Rica (MNCR) have excavated 6 stone spheres as
part of a wider project to preserve the monuments."
