Caral

The Sacred City of Caral-Supe, or simply Caral, is an archaeological site in Peru where the remains of the main city of the Caral civilization are found. It is located in the Supe valley of Peru, near the current town of Caral, 182 kilometers north of Lima, 23 km from the coast and 350 metres above sea level. It is attributed an antiquity of 5,000 years and it is considered the oldest city in the Americas and one of the oldest in the world. No other site has been found with such a diversity of monumental buildings or different ceremonial and administrative functions in the Americas as early as Caral. It has been declared a Humanity Cultural Heritage site by UNESCO.

The Caral culture developed between 3000 and 1800 B.C. In America, it is the oldest of the pre-Hispanic civilizations, developing 1,500 years earlier than the Olmec civilization, the first Mesoamerican complex society.
