A newly discovered stone structure in the Mendoza region of Argentina has captured the attention of archaeologists worldwide. The site, only visible from above and encircled by trenches arranged in geometric patterns, has been described as a "historical marvel" by the conservative Argentine newspaper La Nación. The structure lies on a remote plateau more than 3,500 meters above sea level, a location that makes it difficult to access and study. Researchers have compared it to the famous Nazca geoglyphs in Peru, but Horacio Chiavazza, a researcher at the University of Cuyo, said it is "not comparable to any other, at least for now." The discovery was made by Carlos Gobbi, an Andean mountaineer, who noticed the site while using the Google Earth satellite map application in March 2025. Despite multiple attempts to reach the site in September and November, Gobbi was unable to do so due to harsh weather conditions. He finally reached the location in February after a three-day expedition with limited supplies and no access to communication networks. An international team of Argentine and Spanish archaeologists is planning to visit the site during the austral summer. They have already begun analyzing the discovery using the photographs Gobbi brought back. Their research plan includes surveys, sediment analysis, excavations, mapping using drones and satellites, historical context studies, and engagement with local indigenous communities. One hypothesis is that the structure dates back to the Inca period (15th and 16th centuries), though earlier or later origins remain possible. The site may be connected to the Qhapaq Ñan, the extensive Andean road network. However, Infobae reported that the site "does not seem to correspond to a functionally suitable space for habitation, at least not permanently. There is no access to water nearby, nor are there any indications suggesting there was in the past." If confirmed, the site could be an ancient "ceremonial center" of the Inca Empire, a sacred place where rituals, offerings, religious festivals, and astronomical observations took place. Such sites were believed to help ancient civilizations communicate with their deities and maintain "the order of the cosmos," as La Nación noted. If verified, the site would be the southernmost known location of Tahuantinsuyo, the Inca Empire, adding to the understanding of the empire's reach and influence in the region.
