Settlement and Artificial Mummification of the Chinchorro Culture in the Arica and Parinacota Region

A glass floor in a small room on a quiet Arica street lets you look straight down at thirty-two human bodies exactly as archaeologists found them, and they are older than the pyramids by a couple thousand years. That room, Museo de Sitio Colon 10, is the single best reason to detour into Chile’s far north, and most travelers doing the Atacama-to-Peru overland run skip it entirely because nobody told them it existed.

What the culture actually did

The Chinchorro were fishing communities who lived along this hyper-arid coastal strip starting around 7000 BC, and it’s worth separating two dates that get conflated constantly: 7000 BC is roughly when people settled here, while the practice of deliberately preserving the dead only began around 5050 BC, with the oldest confirmed artificial mummy being a child recovered from the Camarones Valley south of Arica. Egyptian mummification did not begin in earnest until roughly 2600 BC, so the Chinchorro were doing this work well over two thousand years earlier, not merely “over a thousand” as is often repeated.

Their method was not the removal-and-reassembly of viscera through a single incision the way later cultures did it. Chinchorro embalmers frequently disassembled the entire body: skin, muscle, and organs were separated from the skeleton, the skeleton was reinforced with sticks and reed cord, the body cavity was packed with ash, feathers, and plant fiber, and the skin (sometimes with a sea-lion skin patch substituted where the original had decayed) was reattached and painted, often in a thick coat of black manganese in the earlier period and red ochre later on. Faces were frequently covered with a plain clay mask with slit or painted eyes. This was not reserved for elites either, which is one of the culture’s strangest features: infants, fetuses, and stillborn children were mummified with the same care as adults, suggesting a belief system built around the whole community’s dead rather than status.

Why UNESCO listed it

The site was inscribed in 2021, not for a single monument but for a cluster of settlement remains, cemeteries, and shell middens spread across the Arica and Parinacota region, recognized as the oldest known evidence of artificial mummification anywhere on earth. The listing is also partly a conservation intervention: the same coastal humidity swings that once helped preserve these bodies are now degrading them faster than expected, and the tissue on several specimens has begun to blacken and decompose in ways conservators are still working to halt.

Where to actually see them

Skip any lingering mention of a “Museo Arqueologico Tamarugal”: that’s not the current name. Two sites matter. The Museo Arqueologico San Miguel de Azapa, about 12 kilometers east of central Arica in the Azapa Valley, holds the largest institutional collection, with around fifteen mummies on public display out of a much larger research collection, plus strong context on daily Chinchorro life; a taxi or colectivo from downtown Arica runs about fifteen minutes. The second, more striking site is Museo de Sitio Colon 10 in the city center itself, built directly over a mass grave discovered by accident during hotel construction in the 1980s. You view the burial through reinforced glass flooring rather than in display cases, and an audio guide accessible by QR code walks you through what you are looking at in roughly twenty minutes. Entry to both sites is inexpensive by South American museum standards, generally just a few dollars, though prices and hours shift seasonally enough that checking the same day online before you go is worth the two minutes it takes, since both have occasionally closed for conservation work with little notice.

Getting there and timing it right

Arica sits at the very top of Chile, closer to Peru than to most of its own country. From Santiago, LATAM, JetSMART, and Sky Airline all fly the route several times daily; budget roughly two and a half hours in the air and fares that can run as low as thirty to forty dollars one-way if booked off-peak, though last-minute prices climb fast. If you’re coming from Peru, Tacna sits just 56 kilometers north across a border crossing open around the clock, connected by frequent buses that take under two hours including immigration formalities, making Arica an easy add-on to a southern Peru itinerary rather than a dedicated Chile trip. The desert climate here is mild and dry nearly year-round, so the more useful timing consideration isn’t season but museum hours: aim for a weekday morning, since both sites draw cruise-excursion crowds when ships dock and get noticeably busier midday.

The gotcha worth knowing

Because Arica is a border town, plenty of unofficial “tour guides” hang around outside Colon 10 and the Azapa museum offering combined mummy-and-valley tours at inflated flat rates paid in cash upfront. The official audio guide covers the material better than most of these pitches, and if you do want a guided valley trip pairing the museum with the Azapa geoglyphs and San Miguel church, book it through an established Arica agency rather than off the street. Pair your museum visit with a walk up El Morro de Arica afterward, the clifftop fort overlooking the city, since it closes earlier than the sun sets and is easy to miss if you spend the whole afternoon underground with the mummies.
