Mummies and ancient offerings have already been found in the Huaca Pucllana site, and experts see the site as a Pandora's Box with much more to be found.
While best known for the mountain-top Inca royal retreat of Machu Picchu, Peru was home to various pre-Hispanic cultures that thrived in the centuries before the Inca empire rose to power, mainly along the country's central coast and in the Andes.
"I find it quite interesting that right in the heart of Miraflores, in the middle of the city, surrounded by modern buildings and constructions, an important site is still preserved, the Huaca Pucllana ceremonial center," said Ganoza.
Lima, with 10 million inhabitants, has some 400 huacas, or sites with archaeological ruins, that can be seen in various neighborhoods, according to experts.
