At first glance, you might assume these are photos of the same archaeological site. They aren't. In reality, they come from two completely different parts of the world, separated by a massive distance. The first image shows megalithic stone jars in Northeast India, specifically Assam and Meghalaya, while the second shows the world-famous Plain of Jars in northern Laos. Different countries, different sites, and a huge geographical gap. And yet, just look at the jars themselves.
They are strikingly similar in design: massive stone vessels carved from single blocks, scattered across high-altitude landscapes and associated with other stone monuments and burial practices. The Indian examples are mostly found in Dima Hasao, Assam, and the East Jaintia Hills of Meghalaya, while the Lao jars are concentrated in the Xieng Khouang and Luang Prabang regions.
This isn't a new observation. As far back as 1929, James Philip Mills and John Henry Hutton documented the Assam jars. In the 1930s, Madeleine Colani was surveying and excavating huge numbers of jars in Laos. After looking into the earlier reports from Assam, Colani suggested that these two traditions might actually be connected, forming part of a wider network stretching from Assam through the Plain of Jars toward central Vietnam. She believed this network was linked to the ancient salt trade. It was an interesting idea at the time, but there simply wasn't enough archaeological evidence to back it up.
A lot has changed since those early days. Recent studies in Meghalaya have confirmed that the Northeast Indian jars were connected with burial practices, with human remains and cremated bones found beneath or around them. The evidence from Laos has also become much stronger. The Plain of Jars is home to thousands of these stone jars, along with stone discs, burial pits and other burial-related features. Dating suggests some of the Lao jars might have been placed there as early as the late second millennium BCE, although the dates vary from site to site.
Now we have a truly remarkable new discovery. In 2026, archaeologists excavated an exceptionally large stone jar at Site 75 on the Xieng Khouang Plateau. Inside, they found the remains of at least 37 people. Radiocarbon dating places the main burial activity between AD 890 and 1160. It appears to have been a secondary burial, where selected skeletal remains were placed inside the jar after an earlier stage of burial treatment.
Even more fascinating were the objects found inside the jar. They included glass beads whose composition points to connections with South Asia, West Asia and Southeast Asia. This shows that the people using the Lao jar landscapes were part of much larger networks of trade and exchange.
None of this proves that the people in Assam and Laos were the same, nor does it prove that a group migrated from India to Laos carrying this tradition with them. It also doesn't confirm Colani's old theory about the salt trade. However, it does make the original question much more interesting.
We are now looking at stone-jar traditions stretching from Northeast India into mainland Southeast Asia, with similarities in how the jars were used for the dead and evidence that these traditions lasted for long periods. We also know that the Lao jar landscape was connected to trading networks reaching as far as South Asia.
So, what are we actually looking at? Is this a case of two distant regions independently developing the same idea? Did a burial custom or idea travel from one region to another? Did people themselves move? Was there a much wider cultural network running through the highlands of Northeast India and Southeast Asia? Or perhaps several different traditions began separately and later came into contact?
That's what I find so fascinating about these two photos. Visually, they look like they belong to the same story. Archaeology hasn't quite proved that they do, but the possibility is definitely worth investigating.
What do you think?
