A similar archaeological site was found a short time later in Ecuador.
In 2014, the team unearthed the Montegrande archaeological temple, under an abandoned modern Catholic church, which was a dump and smokehouse —just five minutes from the city of Jaen.
In 2016, the Peru-Ecuador Binational Plan contributed S/80,000 (about US$22,857) to the project; another S/100,000 (about US$28,571) was financed by the Provincial Municipality of Jaen. With that money progress was made to show details of the beautiful temple.
The oldest cacao
The civilization that built the temples in Peru and Ecuador is more than 5,000 years old and would be the cradle of cacao. Its remains are located in the Chinchipe-Marañon binational basin.
“Where 20 years ago a conflict took place, now archaeologists work together to investigate the past because we are one people,” Olivera stressed.
The first monumental architecture was discovered at the source of Mayo Chinchipe River, in Ecuador, where 32 carbon-14 dating (tests) were carried out, which made it possible to identify a fermented drink of Theobroma cacao, while it was thought that this fruit had originated in the Mesoamerican region —related to the Olmecs.
“Archaeological evidence indicates that it would be found in the upper part of the Chinchipe-Marañon binational basin, evidence of 2,000 years before the Olmecs; that means 5,500 years old. That makes it the oldest cocoa in the world,” said Olivera, who believes that this culture should be called Marañón —in honor of the most important course in the Amazon.
