Ancient CivilizationsArchaeologists find 3,500-year-old city in Peru which once served as a trading hub – with sculptures and jewellery inside Posted on July 25, 2025 by Administrator An ancient city has been discovered in Peru that once was a trading hub thousands of years ago. The 3,500-year-old settlement, named Peñico, is located in the northern Barranca province – close to where the Caral civilisation, the oldest in The Americas, developed 5,000 years ago. Archaeologists believe Peñico was likely a trading hub linking Pacific coast cultures with those in the Andes mountains and the Amazon basin.
