A Ministry of Culture team on Tuesday unveiled 11 pre-Inca tombs located inside Peru's National Sports Village, where excavation work began last December.

The structures are relics of the Lima and Yschma cultures, which flourished during the periods A.D. 200-700 and 1100-1400, respectively.

The director of the project to excavate the Tupac Amaru A and B archaeological sites, Fernando Herrera, in presenting the work done so far said that the importance of the graves is that they were found intact, despite the fact that about 50 percent of the monument was lost during nearby modern construction activities.

"What we can see is what has been saved from centuries of reductions, looting and, in general, urban expansion that has been reducing and eliminating the great majority of the tombs that were there in the three valleys in the current Lima Metropolitan area," Deputy Culture Minister Rafael Varon said.

The site includes an adobe base and has rooms that contain mummified bodies along with offerings of ceramics and seeds.

The location served as an administrative center for the Lima culture and afterwards became a ritual zone for the Yschma, Herrera said.

Scientists have not yet been able to determine either the sex or the age of the mummified individuals. EFE
