Site 7A, Houaphanh, Laos
Hintang standing stones
A Bronze Age proposal, and no radiocarbon yet (cists, discs with a star, and a sixteenth-century bowl in the same soil)
On the ridges of Houaphanh, mica-schist slabs stand in groups, some of them over 3 metres. A 1930s dig found stone-lined cists with human bone underneath. A 2025 trench, the first in ninety years, found a star-cut disc lying on a bowl of the fifteenth or sixteenth century. The radiocarbon samples are not yet dates.
Why this is extraordinary
Hintang, in Houaphanh, is a landscape of mica-schist slabs on ridges. Some stand more than 3 metres. A survey counted 72 sites, more than 1,500 slabs and 150 discs. In the 1930s, stone-lined cists under the groups held human bone, and the digger dated the tradition to a Bronze Age of about 1700 to 500 BCE from bronze vessels, ornaments, glass beads, pots and perforated schist pendants, earlier than the megalithic jars further south in Xieng Khouang. That comparison is why Hintang matters next to the Plain of Jars. It is a comparison of objects, not a radiocarbon date.
In 2025 a team went back, mapped the old sites, and dug the first trench in ninety years, at site 7A, three slabs at 1,430 metres. A 2 by 2 metre square, half a metre deep, produced low-fired quartz-tempered sherds and a perforated disc 43 millimetres across and 9 millimetres thick, incised with a star. Twenty-eight discs of that stelliform kind were already on record from the 1930s, taken then as the same age as the stones. This one lay on a piece of glazed stoneware with its foot ring, painted in iron, and read as a Thai bowl of the fifteenth or sixteenth century CE. A Bronze Age disc on a sixteenth-century bowl is a disturbed layer, which the 1930s account had already suspected, from later pots and from local memory of old digging. Samples for a radiometric date were collected. They are not results yet.
The star is the sky motif the complex actually has. It is cut on a small disc, not aligned as a row of stones to a sunrise. No azimuth for the groups is published, and fire, farms and building have moved some slabs, so a bearing taken today can be a bearing of a shifted stone. What the star meant to the people who cut it is not in the reports.
What this changes: if a sealed cist dates to the proposed Bronze Age, Hintang is an earlier megalithic burial tradition than the jars, with a star on the discs that went with the dead. If the only centuries in the new trench are late, the slabs are still there, and the Bronze Age date goes back to being a proposal about objects that may not be in place.
Why it matters
If the stones and the discs are Bronze Age, Hintang is older than the Plain of Jars and is one of the earlier megalithic traditions on the mainland. If the disc’s place in the soil is the truth, the star and the slab have been moved, and the Bronze Age date is a proposal waiting on a laboratory.
Hintang means standing stone. The groups sit on ridges and saddles above the valleys. A survey programme counted 72 sites, more than 1,500 slabs, and 150 stone discs. The 2025 work went back to relocate those sites and to take the first samples for a radiometric date. The pin is site 7A, the place they chose to dig.

What is still unexplained
These sit beside the consensus account, with the same visual weight. None of them is marked solved.
Location and dating
- Location
- Site 7A, Houaphanh, at the coordinate printed for the 2025 excavation, about 20.146 north and 103.867 east, 1,430 metres above the sea. The other groups are the same landscape and are not separate pins. The Plain of Jars is a different province and a different room.
- Period label
- Current consensus — open to revision Proposed Bronze Age, about 1700 to 500 BCE, from the 1930s objects. Not confirmed by radiocarbon. A glazed bowl in the 2025 trench is fifteenth or sixteenth century CE and shows the soil has later material in it.
- How this dating was done
- Typology of bronze, beads and pendants from the 1930s. The new project is the first attempt at a radiometric date. The bowl is dated by its glaze and form.
- What could change it
- The radiocarbon or luminescence result the 2025 samples were taken for, from a cist that has not been turned over by later digging.
What is actually there
- More than 1,500 mica-schist slabs and 150 discs, across 72 sites.
- Some stones over 3 metres. Cists with human bone underneath.
- Site 7A disc, 43 millimetres across, 9 millimetres thick, with a star cut on it.
- That disc lay on a glazed bowl of the fifteenth or sixteenth century CE.
- Samples for a radiometric date were taken in 2025 and are not yet results.
Open questions
| Question | Status |
|---|---|
| Are the standing stones and the star discs one Bronze Age burial tradition? | Open. The cists and the discs were published together in the 1930s. The 2025 disc was not in a sealed Bronze Age layer. |
| Do the rows point at anything in the sky? | Open, and currently unsupported. No azimuth is published, and some stones have been moved. |
The current narrative
Where publication stands today. It is the best-supported reading, and it is open to revision. It is not a verdict.
The current narrative — open to revision
Bronze Age burial markers
The slabs mark mortuary cists of a mainland Bronze Age, about 1700 to 500 BCE, earlier than the jar fields, and the star discs belong with them.
What supports this
- Stone-lined cists with human bone were dug in the 1930s, with bronze, glass beads and perforated schist pendants.
- Twenty-eight star discs were reported from the same complex and taken as contemporary.
- The stones prefer ridges, a repeated choice, not a scatter of later boundary posts.
What pushes back
- There is still no radiocarbon date. The 2025 paper says the samples are the first attempt.
- The disc in the new trench lay on a fifteenth- or sixteenth-century bowl. Disturbed soil can bury an old disc on a new pot, and it can also mean the disc is not old.
- Later visitors, including the treasure hunting the 1930s account already heard about, have mixed the layers.
What would settle it
It is the centre because the cists and the grave goods are the evidence that exists, and the jar sites are a comparison the first excavator already made. It moves when the new dates are published, in either direction.
Emerging narratives
Other published readings. Each may be right. None is adopted here unless the evidence carries it.
An emerging narrative
A ridge tradition whose layers are mixed
The standing stones may be old, but the objects now found with them include much later pottery, and the Bronze Age label is ahead of the laboratory. The star disc cannot be used as a date until it is found in a layer that has one.
What supports this
- A glazed bowl of the fifteenth or sixteenth century CE was under the disc at site 7A.
- The 1930s report already described disturbed sites and later vessels.
- Modern clearing has moved some slabs, so today’s lines are not all ancient lines.
What pushes back
- Human bone in stone cists, with bronze, is a burial tradition whether or not a disc has stayed put.
- One disturbed square does not redate 72 sites.
- A later bowl in a pit is what digging and slope wash do to a ridge. It does not by itself make the slabs modern.
What would settle it
It stays because the 2025 trench was dug to test the old date and the first object it can hang a century on is a late bowl. It is not the centre while the cists and the bronze are still the larger record.
Should the current view be reevaluated?
Open to revision
The stones and the cists are real. The century is a 1930s proposal, and the first new trench found a star disc on a much later bowl. Open waits on the dates that were collected for this.
What drives this
- More than 1,500 slabs, cists with human bone, a Bronze Age proposal of about 1700 to 500 BCE.
- A 43-millimetre star disc on a fifteenth- or sixteenth-century bowl.
- Radiometric samples taken, not yet published.

If the contested reading is right
What would follow if a reading that is not the consensus turned out to be true, and what could settle it. This explains the stakes. It does not adopt the reading.
The discs and slabs are not a single Bronze Age moment
Hintang would stay a great ridge of standing stone, and it would drop out of the claim to be older than the Plain of Jars until a sealed cist is dated. The star on the disc would be a motif whose century is unknown.
Why it is still worth a test
The radiocarbon or luminescence results from the 2025 samples, from a context that does not include the glazed bowl.
