Utility workers installing a natural gas pipeline in the Puente Piedra district on the outskirts of Lima, Peru, discovered a pre-Inca mummy estimated to be around 1,000 to 1,100 years old. The mummy is believed to be that of an adult woman from the pre-Inca Chancay culture. The discovery occurred just half a meter below the surface during excavation work conducted by the gas company Cálidda. Following the finding, pipeline installation was temporarily halted to allow archaeologists to carefully excavate and recover the remains and related artifacts. This incident highlights the presence of pre-Hispanic tombs beneath the modern infrastructure of Lima. Since beginning operations in 2004, Cálidda has reported over 2,200 accidental archaeological discoveries during its projects. The find has been confirmed by multiple sources including local archaeologist José Aliaga and the gas company involved in the work.
