A team of U.S. and Peruvian researchers made new discoveries recently in Peru’s Chavin de Huantar archaeological site including three underground galleries, ceramic pieces and human remains.
The archaeologists have been working since June to excavate the three galleries in the complex, which is located in the province of Huari in Peru’s Ancash region.
At the excavation site, they found ceramics, tools and an intact human burial site.
Stanford University professor John W. Rick leads the Archaeological and Conservation Research program of Chavin. He dated the galleries to the years between 1,300 and 550 BC and show that Chavin had a bigger underground system than originally known.
This particular excavation used small robots with built in microcameras to explore the underground passageways.
According to archaeologists, Chavin was home to different cultures through the ages and held a high cultural and religious importance.
Rick said they are aware of some 35 galleries built in different periods and that dozens of structures have not yet been unearthed.
