Burial jars at the Plain of Jars site.

Researchers Renew Efforts to Solve the Puzzling Plain of Jars Site

Although there is still a long way to go, researchers have found new information on the mysterious Plain of Jars site located in the central Lao province of Xieng Khouang. Human remains dating to the Iron Age, between 2500-3000 years ago, have been unearthed. These and other artifacts are beginning to shed new light on ancient mortuary practices at the site.

Archaeology reports that there were three types of burials found during the excavations. Some individuals were buried whole, other burials were bundled bones, and still more were bones found placed in ceramic vessels. According to Shanghai Daily , the remains were spread out as well, with the first two individuals found 70 cm (27.6 inches) underground and a third discovered about 13 meters (42.7 feet) away.

“With our research, because we’ve been able to uncover a fair amount of human bone—we’ve got seven burials and four probable burials with ceramic jars—so a total of 11 mortuary contexts. We’re hoping we’ll be able to get some really good information about the people,” said Dougald O’Reilly of Australian National University.

Speaking to Xinhua, O'Reilly said:

“Our research, while in preliminary stages, has revealed a wide range of mortuary practices. Such diversity of practice in disposal of the dead is uncommon in one culture... there may be several explanations for this diversity and we hope to establish why this is the case. It is hoped that the knowledge gained from our research will be of assistance in seeing these sites nominated as UNESCO World Heritage."

The researchers also speculate that the Plain of Jars sites may be linked with similar sites in India’s northeast region of Assam.

The project is entitled Unravelling the Mysteries of the Plain of Jars , Lao PDR. It is a five-year research endeavor that is funded by the Australian Research Council and is a joint project being led by the Australian National University’s O’Reilly in cooperation with Monash University archaeologist Louise Shewan, and the Lao Ministry of Information, Culture and Tourism, represented by Archaeology Division Director Dr. Thonglith Luangkhoth.

The team used Ground Penetrating Radar to guide the excavation before digging up the remains. Isotopic and chemical analysis are planned for the bones, with hopes that the tests will provide information on the ethnicity of the people linked to the site.

As Ancient Origins writer April Holloway wrote :

“Little is known of the people who carved the huge containers and the jars themselves give little clue as to their origins or purpose. According to local legend, the jars were created by a race of giants, whose king needed somewhere to store his rice wine. The wine was to be consumed at a great feast to celebrate an illustrious military victory thousands of years ago. Legend tells of an evil king, named Chao Angka, who oppressed his people so terribly that they appealed to a good king to the north, named Khun Jeuam, to liberate them. Khun Jeuam and his army came, and after waging a great battle on the plain, defeated Chao Angka.”

The Plain of Jars is composed of at least 3,000 massive stone jars that measure up to 3 meters (9.8 feet) tall and weigh several tons. Most are made of sandstone but there are others of much harder granite and limestone. As the jars have lip rims, it is thought that they were originally covered with lids. Past excavations have found a few stone lids to support this, although it is more likely that the main material for the lids would have been wood or ratan.

The latest field work uncovered an ancient burial ground in a region that is known as Site 1, with more than 300 stone jars, stone discs, and markers. O’Reilly said: “This is one of the great enigmas of the Jars’ sites. These massive stone jars – some of them weighing up to 10 metric tons, that have been dragged eight to 10 kilometers from a quarry site and set up in groups.”


The idea of a race of giants makes sense, particulary since we have found bones of gigantic people around the world.  

Our entire idea of the past lies shrouded in 19th century European and American pseudo-scientists, who had to fit everything into their narrow beliefs about their own superiority and perfection.

The whole idea of evolution came into being to explain how the most perfect being imaginable – the English gentleman – could have come into existence without a god.

Evolution doesn’t have any room for giants, or elves, or fairies or any of the other creatures who fill up myths and lore around the world.  Evolution “knows” these primitive morons made all these tales up, because these creatures couldn’t have existed.

And as the commenter Tsurugi stated, when archaeologists can’t explain something, they call it a tomb.  Big people made these jars for a big people purpose.  We don’t understand it, so we make up an answer.

I'm really glad that someone is working on understanding these objects. I'm not sure what they think they are learning about the stone jars by unearthing burials in the area, but I'm glad they're looking into the matter, at least.

If I remember correctly, the "best guess" of mainstream archaeology has been that the jars are basically jar-shaped sarcophagi--an idea that was based on the fact that a few of the jars were discovered to have human remains in them. It seemed to me that was entirely ignoring the possibility of intrusive burials and such. Plus, mainstream archaeology thought it unlikely that the jars had stone lids, which IMO conflicted with the idea that they were coffins.
It just seemed like the old "I don't know, therefore tombs" thing that archaeology has so often done.

On the subject of whether there might have been stone lids for the jars, I came across some excellent photographs of some giant stone jars in Sulawesi in Indonesia that look exactly like those in Lars, and these still had their lids with them. They were beautifully made, with four lizard-like things decorating the top of the lid and possibly serving as handholds(if someone were strong enough to lift one of the lids by hand).

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
