San José, Aug 29 (Prensa Latina) The Diquís Spheres are one of the 15 national symbols of Costa Rica and perhaps the most used to represent the identity of the Central American nation at an international level.
Distinctive in the main buildings of the Powers of the Costa Rican State, these pieces were discovered in 1939 due to deforestation for the cultivation of bananas of an American company.
The set of pre-Columbian chiefdom settlements with stone spheres of the Diquís River, in the area In the south of the country, it was declared a World Heritage Site in 2014 by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and that same year it was turned into a national symbol.
Protected since 1970 by the Government, For some years now, the National Museum of Costa Rica has had a special team for the conservation and restoration of many of them, damaged by time or found semie
With dimensions ranging from 10 centimeters to about 2.6 meters in diameter, a maximum weight of 16 tons and made with granodiorite, gabros and limestone, the set currently totals around 500 pieces, located in the alluvial plain of the Diquís delta (confluence of the Sierpe and Grande de Térraba rivers), on the Osa peninsula and on Caño Island, Puntarenas province.
Although they were made by indigenous people almost perfectly in a period of 1 000 years (between 400 and 500 of our era until the arrival of the Spanish in America), these stones are attributed the most varied origins, from having been brought by extraterrestrials or by descendants of the disappeared Atlantis to mythical-religious associated with the god of thunder Tlachque, who with a giant blowgun threw them against the gods of winds and hurricanes (serkes) to drive them away from their lands.
