Pyu cities about 200 BC to AD 900 (Halin’s sequence may start far earlier)
Three brick cities in the dry zone are the Pyu, 200 BC to AD 900 on the World Heritage listing, with a radiocarbon date of 190 BCE on architecture. A new series at Halin starts in the early third millennium BC, and that early end is either the city or something older underneath it.
Why this is extraordinary
In the dry zone of the Ayeyarwady, three walled and moated cities, Halin, Beikthano, and Sri Ksetra, are what remains of the Pyu kingdoms. UNESCO says they flourished for more than a thousand years, between 200 BC and AD 900. Brick stupas, palace citadels, burial grounds, and canals, some of the canals still in use, sit inside irrigated fields. The listing’s proof of that whole span is radiocarbon from intact architecture back to 190 BCE, read together with inscriptions in Pyu script. Sri Ksetra, near Pyay, is the great southern city. The photograph is a stupa there, across a pond. The pin is the site museum’s coordinate, 18.810 north, 95.288 east, inside the walled area.
The early laboratory story was smaller. Four charcoal dates from Beikthano, two halls that held terracotta burial urns, measured 1950 plus or minus 90, 1880 plus or minus 95, 1725 plus or minus 95, and 1650 plus or minus 85 radiocarbon years before present. On those numbers the halls were placed in the first to fourth centuries AD. Halin’s first dates were read as about the second to the ninth century. A later gathering of dates from all three walled cities concludes they were all functioning by the early centuries CE, which loosens an older habit of lining them up as Beikthano first and Sri Ksetra much later. Functioning by the early centuries is not the same as founded in 200 BC. The listing’s 190 BCE is an architectural radiocarbon. The four Beikthano numbers are charcoal from two buildings. Both can be true of different walls.
In 2024 a series of 94 radiocarbon determinations from Halin, read with the pottery, was published as a sequence from the early third millennium BC to the early second millennium AD. If the early end is corroborated, Halin would be the oldest dated Neolithic site yet in mainland Southeast Asia, and it would bear on how farming entered the region. That early end is not a Pyu city. A Neolithic occupation under a later walled town is a different fact from a brick stupa in 190 BCE. The dispute is which clock you let speak for “the beginning.” A city is a wall, a moat, urn burials, and a script. A scatter of earlier charcoal is a place people used before those things. Calling both Halin is accurate and also easy to blur.
No source used here prints a solstice azimuth for the stupa or for the city wall. Pyu Buddhism shares the wider Buddhist picture of a sacred centre, a vertical axis more than a door aimed at a sunrise. The photograph’s stupa is a dome and a spire, which is that vertical. It is not a measured bearing. The moat and the canals are horizontal and practical. A city plan can be cosmological and still follow the ground it was given. Without a published axis, this room does not invent one.
Bagan, further up the same dry zone, is the later capital. It is a different question from the Pyu beginning. It is noted on the Myanmar page so the famous city is not mistaken for this one.
Why it matters
The start of cities and of Buddhism in this valley is the start of a written Burma. If Halin’s earliest dates are Neolithic farmers, the city is a late chapter on an old site. If they are the city, urban life here is being pushed far behind the stupas. The difference is the whole chronology.
The stupa, the moat, and the spread of dates are the tour. The pin is Sri Ksetra. Halin and Beikthano are the other two Pyu cities in the same listing.

- The Beikthano urn halls, which produced the four charcoal dates, are not in the photograph. The picture is a Sri Ksetra stupa and the pond in front of it.
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
- Sri Ksetra, near Pyay, in the dry zone of the Ayeyarwady basin. The pin is 18.810 north, 95.288 east. Halin lies well to the north, in Sagaing, and Beikthano between them. The three are one World Heritage listing.
- Period label
- Current consensus — open to revision UNESCO’s Pyu span is 200 BC to AD 900, with architectural radiocarbon back to 190 BCE. Beikthano’s urn halls were placed in the first to fourth centuries AD on four charcoal dates. Halin’s 2024 series runs from the early third millennium BC to the early second millennium AD and includes a pre-urban occupation if the early dates hold.
- How this dating was done
- Radiocarbon on charcoal and on architectural contexts, plus inscriptions in Pyu script and the style of bricks and urns. The 2024 Halin paper is a set of 94 radiocarbon results read against pottery.
- What could change it
- A table that labels each of the 94 Halin dates as Neolithic, early urban, or Pyu, with the sample’s context, would stop the early tail from being read as the city. The same for the 190 BCE architectural sample would show whether the carbon is the wall or the ground under it.
What is actually there
- Three moated cities, Halin, Beikthano, and Sri Ksetra, share the listing.
- Beikthano charcoal dates include 1950±90, 1880±95, 1725±95, and 1650±85.
- Urn burials were found inside and outside the Beikthano halls.
- Canals and tanks are still used for farming.
- No solstice azimuth for the stupa or the wall is in the sources used here.
Open questions
| Question | Status |
|---|---|
| Does Halin’s early third millennium date the Pyu city? | Open. The 2024 paper offers a Neolithic beginning at the place. The city, on the listing, is the walled, inscribed, Buddhist millennium from 200 BC. |
| Were the three cities a sequence or a set? | Open. Older readings lined them up. Newer dates put all three in operation by the early centuries CE. |
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
A Pyu millennium, 200 BC to AD 900
Halin, Beikthano, and Sri Ksetra are the brick cities of Pyu kingdoms that lasted from about 200 BC to AD 900, dated by architecture, urns, script, and radiocarbon, including a date of 190 BCE.
What supports this
- The listing ties that span to radiocarbon from intact architecture and to Pyu inscriptions.
- Moats, stupas, citadels, and working canals are the visible city, not a scatter of charcoal.
- A review of the dates puts all three cities in use by the early centuries CE, which supports a long overlapping urban period.
What pushes back
- Beikthano’s best-known charcoal dates fall in the early centuries AD, later than 190 BCE, so the start is carried by other samples.
- Halin’s 94 dates include an early third-millennium tail that is not urban. A careless reading will glue it to the kingdom.
- “Functioning by the early centuries CE” does not prove a foundation in 200 BC at each of the three.
What would settle it
It is the listing’s reading, and the walls and the script carry it. The early Halin tail is a different occupation until someone shows it is a wall.
Emerging narratives
Other published readings. Each may be right. None is adopted here unless the evidence carries it.
An emerging narrative
Halin is much older than the Pyu label
The place called Halin was occupied from the early third millennium BC, so the Pyu city is a late phase on one of the oldest dated Neolithic sites in mainland Southeast Asia.
What supports this
- Ninety-four radiocarbon determinations and the pottery are published as that long sequence.
- If the early end is corroborated, the paper says Halin would be the oldest dated Neolithic site in the mainland region.
- A city often sits on an older village. Finding the village changes the map of how farming arrived.
What pushes back
- A Neolithic date under a town does not date the town’s wall, its urns, or its Buddhism.
- Corroboration is the paper’s own condition. An early tail can be old charcoal in later fill.
- Sri Ksetra’s stupa and the 190 BCE architectural date are not helped, or harmed, by a farmer at Halin two thousand years earlier.
What would settle it
It is a real extension of the place’s history. It is not a redating of the Pyu kingdoms unless the early samples are shown to belong to bricks and inscriptions. They have not been.
Should the current view be reevaluated?
Open to revision
The three cities and the long Pyu span are well supported. Halin’s new series adds a possible Neolithic beginning that must be kept distinct from the walled city. No sky bearing is published for the stupa.
What drives this
- A listing span of 200 BC to AD 900 with a 190 BCE architectural date.
- Four Beikthano charcoal dates in the early centuries AD.
- Ninety-four Halin dates reaching the early third millennium BC.

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.
Halin’s early dates are a real Neolithic occupation
Farming communities were at this dry-zone site thousands of years before the Pyu walls, and the kingdom inherited an old place rather than founding an empty one.
Why it is still worth a test
Contexts for the earliest of the 94 dates, published so a reader can see they are not residual charcoal in a Pyu pit.
