• A 4,000-year-old painted stone from Wetar Island may change how we understand the Austronesian story.⠀
⠀
Archaeologists excavating Huknaur 1 in Southeast Indonesia found a painted plaque with a red sun-ray motif linked to the Austronesian Painting Tradition — a wider visual tradition known from eastern Indonesia and nearby islands.⠀
⠀
What makes this find so important is that the plaque appears to be older than the first pottery at the site. That means a shared symbolic tradition may have been present before the full Neolithic package usually associated with Austronesian expansion. This discovery suggests that ideas, symbols, and identity may have travelled ahead of pottery.⠀
⠀
It is a reminder that the spread of people goes beyond tools, crops, or ceramics, and may also have been about belief, belonging, and a shared visual language carried across the sea.⠀
⠀
Swipe through to see why this small object has such big implications.⠀

  • Plaques, Ponds and Provenance⠀
⠀
This week’s newsletter begins with a 4,000-year-old painted plaque from Wetar Island — a small object with a big story.⠀
⠀
The plaque carries a red sun-like motif linked to the Austronesian Painting Tradition, and it appears before pottery at the site. That suggests visual symbols and shared ideas may have moved through maritime Southeast Asia before some of the usual archaeological markers we associate with Austronesian expansion.⠀
⠀
Also this week: archaeology beneath Angkor’s Sras Srang, suspected Ban Chiang artefacts offered for return from Switzerland, and more heritage news from across the region.⠀

  • How do you make a 3-metre stone stand upright for centuries?

At Hintang in northern Laos, archaeologists are beginning to answer that question.

In 2025, a Lao-Australian team excavated Site 7A — the first excavation at a Hintang standing-stone site in around 90 years. Beneath the surface, they found that the stones had been set deeply into pits, with smaller rocks packed around their bases to stabilise them. Roughly one-third of each standing stone was buried underground.

One big question remains, though — how old are the Hintang stones?

Samples were collected for dating, but those results are still being analysed. So, for now, we understand a little more about how these monuments were built.

  • Angkor’s water system is famous for its scale: enormous reservoirs, long canals, and monumental engineering.⠀
⠀
New research by archaeologist Sarah Klassen highlights how Angkor’s agricultural system also depended on more than 1,000 local temple communities spread across the Greater Angkor Region. These communities helped organise labour, manage local water systems, and coordinate rice production - and suggests that Angkor’s success was built through a combination of top-down and bottom-up management.⠀
⠀
The state created the large hydraulic framework. Local communities adapted to it, expanded around it, and helped make the wider agricultural landscape function.⠀
⠀
Over time, however, this balance changed. Land and resources became increasingly concentrated, the system became more centralised, and some of the flexibility that had helped Angkor cope with earlier environmental stress may have been lost.⠀

  • This week on Southeast Asian Archaeology: fish traps, tidal flats and maritime memory.⠀
⠀
The main story looks at tambek, stone tidal fish weirs on Bawean Island in Indonesia. A new study records 54 of these structures and shows how they reflect local knowledge of tides, fish behaviour, construction, ownership and coastal life.⠀
⠀
Also in the highlights:⠀

  • How do you catch fish without a net, hook or boat?⠀
⠀
On Bawean Island in Indonesia’s Java Sea, coastal communities developed tambek: stone walls built across the intertidal zone that use the movement of the tides to trap fish.⠀
⠀
A new study by Dwi Kurnia Sandy and colleagues documents these remarkable structures through archaeological survey, drone photography, interviews, historical sources and mapping. The researchers recorded different forms of tambek, from relatively simple U-shaped structures to more elaborate V-shaped systems directing fish into enclosed spaces. Their locations were carefully chosen around productive coastal environments, particularly extensive intertidal zones and mangroves.⠀
⠀
But tambek were more than fishing equipment. They were also part of Bawean’s social landscape. Individual structures could belong to particular families, with ownership remembered and passed down across generations. Tambek could even be traded, while customary rules governed who could fish around them at different stages of the tide.⠀
⠀
Today, new tambek are no longer being built and many surviving structures are little used or abandoned. The researchers link their decline to modern fishing technologies, damage to reefs and mangroves, and the gradual loss of knowledge about how the structures were used and maintained. Some have even been dismantled, with their stones reused for coastal infrastructure.⠀
⠀
The study highlights how archaeology can document not only things from the distant past, but also traditional technologies and knowledge systems that are disappearing within living memory.⠀

via Xinhua/Straits Times, 31 March 2024: Cambodia, under the leadership of Prime Minister Hun Manet, is set to nominate ten cultural properties, including seven tangible and three intangible assets, for UNESCO’s World Heritage List. The move aims to gain international recognition and preservation for significant sites like Banteay Chhmar Temple, Phnom Kulen, and cultural practices such as the Cambodian Songkran and Khmer wedding traditions.

Cambodian Prime Minister Hun Manet announced plans on March 31 to nominate seven tangible and three intangible cultural properties for inscription on Unesco’s prestigious world heritage list.

The seven properties for which tangible cultural heritage status is to be sought are the former M-13 prison, Tuol Sleng Genocide Museum and Choeung Ek Genocidal Centre; Banteay Chhmar Temple; the site of Angkor Borei and Phnom Da; Preah Reach Troap Mountain historical site; Preah Khan Kampong Svay Temple; Beng Mealea Temple and Kulen Mountain historical resort, he said.

The three properties planned for the intangible cultural heritage of humanity list are the Cambodian Songkran, traditional woven scarf krama and the Khmer wedding tradition, he added.
