Eight well-preserved mummies at least 1,000 years old were accidentally discovered during gas utility operations in Lima, the capital of Peru.

The tomb with the 8 mummies was found by workers digging on a road in Carabayllo area and estimated to date back to the era of the Ichmaa culture that flourished in the area around 1100 AD, before the Incas.

Six of the mummies are estimated to belong to babies and children, which is why the authorities believe that this is a children’s cemetery.

The children probably died of anemia and starvation “due to a climatic event that affected local agriculture,” said Jesus Bahamonde Schreiber, an archaeologist at the Calidda gas company.

Inside the tomb were found two adult mummies with their belongings – opium pipes, shoes and Chinese playing cards.

Archaeologists say that more than 1,900 historical finds have been found in the area since the campaign to expand the natural gas pipeline in the region began.
