LIMA, June 20, 2025 (BSS/AFP) - Peruvian gas workers this week found a thousand-year-old mummy while installing pipes in Lima, their company said, confirming the latest discovery of a pre-Hispanic tomb in the capital.

The workers found the trunk of a huarango tree (a species native to coastal Peru), "which served as a tomb marker in the past," at a depth of 50 centimeters (20 inches), archaeologist Jesus Bahamonde, scientific coordinator of Calidda gas company, told reporters.

The mummy of a boy aged between 10 and 15, was found at a depth of 1.2 meters, he added.

"The burial and the objects correspond to a style that developed between 1000 and 1200," he said.

The remains discovered on Monday were found "in a sitting position, with the arms and legs bent," according to Bahamonde.

They were found in a shroud which also contained calabash gourds.

Ceramic objects, including plates, bottles and jugs decorated with geometric figures and figures of fishermen, were found next to the mummy.

The tomb and artifacts belong to the pre-Inca Chancay culture, which lived in the Lima area between the 11th and 15th centuries.

They were discovered while gas workers were removing earth from an avenue in the Puente Piedra district of northern Lima.

In Peru, utility companies must hire archaeologists when drilling the earth, because of the possibility of hitting upon heritage sites.

Calidda has made more than 2,200 archaeological finds since 2004.

Lima is home to over 500 archaeological sites, including dozens of "huacas" as ancient cemeteries are known in the Indigenous Quechua language.
