Archaeologists working on a Wari complex in Peru’s central Andean region of Ayacucho said they may have found 1,000-year-old mausoleums, daily Peru.21 reported.

Archaeologist Martha Cabrera said specialists have uncovered two underground galleries at the complex, which is located in the district of Quinua in the Huamanga province.

The first gallery is 15 meters long, 1.4 meters wide and about 1.75 meters tall, Cabrera said. The other gallery is about 8.5 meters long.

The archaeologist said that they found remains that suggest the complexes were collective burial sites for elite members of the Wari civilization.

The Wari culture settled over much of current Peru’s south-central coast and highlands from 500 AD to 1000 AD, prior to the advances of the Inca Empire.

Cabrera has been working for over 10 years on Wari sites in the area with archaeologist Jose Ochatoma, who said that a six-meter long stone table was found as well as the remains of some 60 people.

Work on these galleries began in 2012, funded by the Fondo Camisea (Focam).
