Chavín de Huántar: An Oracle at the Crossroads

Chavín de Huántar lies in the region of Áncash, at the confluence of the Mosna and Huachecsa rivers on the eastern slope of the Cordillera Blanca, at an altitude of about 3,180 meters — a strategic position at the crossroads of routes linking the Peruvian coast, the sierra, and the Amazon jungle. The first systematic scientific study of the site was carried out by Julio César Tello beginning in 1919, who proposed Chavín as the "mother culture" of Andean civilization, a hypothesis later revised in light of the earlier findings at Caral and at the coastal Cupisnique culture, though Chavín retains its centrality within what archaeologists call the Early Horizon. Later excavations by John Rowe, Luis Guillermo Lumbreras, and, systematically from the 1970s and 1980s onward, Richard Burger substantially revised the site's chronology, placing its occupation at around 1200–500 BCE across the Urabarriu, Chakinani, and Janabarriu ceramic phases. Research led by John Rick of Stanford University from the 1990s onward further refined the architectural sequence, establishing that the "Templo Viejo," or Old Temple, dates to around 900 BCE, while the major expansion into the "Templo Nuevo," or New Temple, occurred around 500–400 BCE. UNESCO declared the site a World Heritage Site in 1985.
