The archaeological site, known as Penico, was a meeting point for trade between the first human communities on the Pacific coast and those from the Andes and Amazon regions, researchers have said.

Located in the Supe valley, some 110 miles (180 kilometers) north of the Peruvian capital Lima and around 12 miles from the Pacific ocean, Penico was a hilly landscape before exploration work began in 2017.

Archaeologists believe it could hold insights into why the Caral civilization -- which flourished between 3,000 and 1,800 BC -- faded.

At the opening ceremony, artists from the region played pututus -- the traditional shell trumpets -- during an ancestral ritual offering to the Pachamama, Mother Earth, consisting of agricultural products, coca leaves and local drinks.

Penico was an "organized urban center devoted to agriculture and trade between the coast, the mountains and the forest," archaeologist Ruth Shady, who leads research on the site, told AFP.

The site itself dates back to between 1,800 and 1,500 BC, she added.

It was built on a geological terrace 2000 feet (600 meters) above sea level, parallel to a river to avoid flooding.

Research carried out by the Peruvian Ministry of Culture has identified 18 constructions, including buildings and residential complexes.

Researchers believe that it was built at the same time as the first civilizations in the Middle East and Asia.

Shady said researchers are hoping the site can shed light on the crisis they think helped hasten the end of the Caral civilization.

This crisis, she said, was linked to climatic changes that led to droughts and affected agricultural activities in the region.

"We want to understand how the Caral civilization formed and developed over time, and how it came to be in crisis as a result of climate change," she added.
