Archaeologists in Peru have uncovered the skeletal remains of an adult believed to have been buried as a ritual offering of human sacrifice beneath Huaca Pucllana, an ancient adobe pyramid in Lima.
Researchers unveiled the remains Tuesday at the archaeological site in Peru’s capital. They believe the bones belonged to an adult man who may have been sacrificed during a ceremony marking the closure of a water canal.
The canal was connected to a ceremonial pool near the base of the pyramid. Archaeologists believe the man was buried when the canal was sealed as part of a ritual, raising the possibility that the burial was a human sacrifice.
Gladys Paz, the archaeologist who led the excavation, said the discovery could help researchers better understand the rituals of the Lima culture and reconstruct ceremonies performed centuries ago.
Burial offers clues to ancient ritual
Paz said the body was placed inside the canal and rested on its left side. The skull faced Huaca Pucllana and the Pacific Ocean. Researchers are studying the remains and their archaeological context for evidence that could explain the circumstances surrounding the burial.
The Lima culture flourished along Peru’s arid central coast between the first and seventh centuries, about 700 years before the rise of the Inca Empire. Human sacrifice is known from other periods of ancient Peru.
Another study has reexamined Inca sacrifice victims using modern forensic methods, while archaeological evidence has also revealed ritual sacrifice traditions among earlier societies.

Huaca Pucllana was one of the culture’s most important ceremonial and administrative centers. The site was already ancient by the time Spanish conquistadors founded Lima in 1535. The pyramid was built largely from adobe bricks and remains a prominent reminder of the civilizations that occupied the region before the Inca.
Peru has produced evidence of monumental ceremonial architecture stretching back thousands of years. Archaeologists recently uncovered a 5,000-year-old fire altar at a Caral site, while another discovery revealed a 3,800-year-old ceremonial offering at Peñico.
Ancient pyramid stands amid modern Lima
Today, Huaca Pucllana rises within one of the most developed parts of the Peruvian capital. Parks, leafy streets and apartment buildings surround the archaeological complex near the districts of Miraflores and San Isidro.
The site is open to tourists. A restaurant at the complex serves Peruvian dishes including ceviche, stir-fried beef and roasted alpaca meat, creating a striking contrast between the ancient monument and the modern city around it.
The discovery also highlights how much archaeological material remains beneath Lima. Peru’s government says more than 400 archaeological sites are scattered across the metropolitan area.
Archaeological remains are common along Peru’s coast
Pieter Van Dalen, an archaeology professor at the National University of San Marcos who was not involved in the excavation, said discoveries of tombs, mummified remains and other burial-related objects are common along Peru’s coast.
Ancient remains have sometimes surfaced unexpectedly during modern construction. Workers digging canals to install gas pipelines, for example, have encountered archaeological material.
Similar finds elsewhere in Peru show how modern development can expose much older layers of settlement. A planned swimming pool in Cusco, for example, became an archaeological site after workers uncovered pre-Inca remains.
The newly uncovered skeleton at Huaca Pucllana adds to that extensive archaeological record. Further examination of the remains could provide researchers with more information about the individual and the circumstances of the burial.
The evidence may also help archaeologists determine whether the man was killed as part of the ceremony or whether his remains were placed in the canal as an offering after his death.
