Pre-Columbian Chiefdom Settlements with Stone Spheres of the Diquís, located in southern Costa Rica, illustrate the physical evidence of pre-Columbian hierarchical societies. The exceptional stone spheres in this World Heritage Site continue to leave researchers speculating about the method and tools of their production.

The serial nomination of four archaeological sites (Finca 6, Batambal, El Silencio and Grijalba-2), located in the Diquís Delta in southern Costa Rica, illustrates a collection of unique stone spheres located in chiefdom settlement structures of the pre-Columbian period.

The property includes four archaeological sites located in the Diquís Delta in southern Costa Rica, which are considered unique examples of the complex social, economic and political systems of the period AD 500–1500. The four sites represent different settlement structures of chiefdom societies (500-1500 CE) containing artificial mounds, paved areas and burial sites.

The artificial mounds, paved areas, burial sites and, most significantly, a collection of stone spheres between 0.7 m and 2.57 m (27 to 100 in) in diameter, whose meaning, use and production remain largely a mystery. The spheres are distinctive for their perfection, number, size and density, and placement in original locations.

Their preservation from the looting that befell the vast majority of archaeological sites in Costa Rica has been attributed to the thick layers of sediment that kept them buried for centuries.
