In 1999, archaeologists found a teenage Inca girl frozen on a 6,739-metre-high volcano, where she had remained untouched for more than 500 years.

In March 1999, archaeologists climbing one of the highest volcanoes in the Andes discovered something that had never been seen before. Near the 6,739-metre peak of Mount Lulailaco, on the border between Argentina and Chile, they discovered the exquisitely preserved body of a teenage Inca girl that had remained frozen for more than 500 years.

Nicknamed “La Doncella” (The Virgin), she appeared to be in such good condition that her hair, skin, facial features, and even the contents of her stomach were largely intact. Scholars believe she was one of three children chosen to perform the important Inca ritual known as capacocha, which offers an unprecedented glimpse into religious beliefs, daily life and the final days of one of South America’s greatest civilizations.

Who is the Inca girl who was discovered frozen on Mount Llullaillaco?

La Doncilla is believed to have been around 13 to 15 years old when she died in the late 15th or early 16th century, at the height of the Inca Empire.

Her body was discovered alongside two young children, a little girl, later nicknamed Lightning Girl, and a boy, buried in separate ceremonial chambers near the summit of the volcano.This exceptional preservation resulted from the extreme conditions on Mount Llullaillaco. At more than 6,700 meters above sea level, temperatures remain well below freezing for most of the year, while the dry mountain air naturally dehydrates the bodies, preventing decomposition.

Archaeologists also found an unusual array of ceremonial offerings buried with the children, including finely woven textiles, feather headdresses, silver, gold and pottery figurines and bags containing coca leaves, reflecting the importance of ritual within Inca society.

Why was the Inca girl taken to the top of the volcano?

Researchers believe that La Doncilla participated in the capacocha ceremony, one of the most important state rituals performed by the Inca Empire.Spanish historical accounts and archaeological evidence indicate that children chosen as capacocha were often chosen because they were considered physically perfect or came from noble families. Rather than being viewed as sacrificial animals in the modern sense, they were thought to have become honored messengers of the gods, helping to ensure fertility, good crops, political stability, or divine favor after important events such as the death of an emperor or natural disasters.Scientific studies of La Doncilla’s hair have revealed fascinating details about her final year. The researchers found that her diet changed dramatically in the months before her death, shifting from regular foods to a richer diet that included more corn and animal protein, foods typically reserved for higher-ranking individuals in society.The analysis also showed increased consumption of coca leaves and alcohol made from corn (chicha) during the last weeks of her life.

Scientists believe these materials may have helped calm the children before leaving them inside the mountain shrine, where they likely died from a combination of extreme cold, low oxygen and exposure.

What scientists discovered Frozen inca girl

La Doncella’s extraordinary preservation has allowed scientists to investigate its final days in extraordinary detail using modern photography, DNA analysis, and protein studies. CT scans showed that many of her internal organs, including her brain, lungs and other soft tissues, remained remarkably intact after more than 500 years in freezing conditions atop Mount Llullaillaco.

One of the most important discoveries came in a 2012 study, “Immune System Response Discovered in a 500-Year-Old Inca Mummy,” led by Angelique Corthals of the Office of the Chief Medical Examiner in New York City and colleagues, which was published in PLOS ONE. Using shotgun proteomics, a technique that breaks down proteins rather than relying solely on ancient DNA, the researchers found evidence that Ladonsiella’s immune system was actively responding to a serious lung bacterial infection shortly before her death. They also identified DNA that belonged to a type of mycobacterium, suggesting that she may have been suffering from a tuberculosis-related illness or another pathogenic fungal infection when she was taken up the mountain. The authors describe it as the first direct evidence of an active immune response discovered in an ancient human mummy, demonstrating that proteins preserved in archaeological remains can reveal diseases that were afflicting people at the time of their death.The study also detected Bifidobacterium bacteria in samples collected from the girl’s lips. Because her body never decomposed, the researchers concluded that it was unlikely to have been contaminated by bacteria after burial. Instead, they suggest it may indicate that she vomited shortly before her death, providing another rare glimpse into her final hours.Combined with previous studies analyzing her hair, diet, and CT scans, these findings turn La Doncilla into one of the most intensely studied archaeological finds in the world.

More than 500 years after her death, scientists continue to uncover new details about her health, her daily life, and the final journey that led her to the summit of one of the highest volcanoes in the Andes.

Why does La Doncella’s discovery still amaze scientists to this day?

More than two decades after its discovery, La Doncilla remains one of the most important archaeological finds in South America.Unlike Egyptian mummies, whose preservation often relies on artificial mummification, the Llullaillaco children were preserved naturally due to the extremely cold and dry conditions of the high Andes.

This has allowed researchers to study ancient DNA, diet, health, and even microscopic traces preserved in their hair and tissue.According to National Geographic, today, La Doncella is housed under carefully controlled conditions at the Museum of High Altitude Archeology (MAAM) in Salta, Argentina, where only one of the Llullaillaco babies is on display at a time to reduce environmental stress.Her story continues to offer a rare and profound human connection to the Inca civilization. More than 500 years after she scaled a sacred mountain, the frozen teenager has become one of archaeology’s most extraordinary windows into the beliefs, rituals and daily life of an empire that once extended across much of western South America.
