Description: 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. They contain artificial mounds, paved areas, burial sites and, most significantly, a collection of stone spheres, between 0.7 m and 2.57 m 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. --From the description at WHC Site, where additional information is available.
  The stone spheres (or stone balls) of Costa Rica are an assortment of over three hundred petrospheres in Costa Rica, located on the Diquís Delta and on Isla del Caño. Locally, they are known as Las Bolas. The spheres are commonly attributed to the extinct Diquís culture and are sometimes referred to as the Diquís Spheres. They are the best-known stone sculptures of the Isthmo-Colombian area. --Wikipedia. Text is available under the Creative Commons Attribution-ShareAlike License.
