Peruvian archaeologists discover 3,800-year-old city that connected the coast, Andes, and Amazon

LIMA, PERU - JULY 18: Archaeologist Mauro Ordonez walks through the remains of the ancient city of Penico, a city believed to have served as an important cultural and commercial hub between the peoples of the coast, highlands, and rainforest some 3,800 years ago, in Lima, Peru on July 18, 2025. After eight years of excavations led by the Ministry of Culture, the site was revealed as part of efforts to understand the earliest pre-Hispanic trade networks following the Sacred City of Caral, considered the oldest in the Americas. The site includes major and minor structures, residential complexes, and ceremonial temples. (Photo by Klebher Vasquez/Anadolu via Getty Images)
