Palau, western Pacific

Thousands of people once lived on Palau's Rock Islands. Nobody agrees when they left.

Palau has a new capital, old stones and an empty lagoon. Here is what was lost, and what is still remembered.

Start from the basics

A place becomes sacred because people do things there, again and again. They bury their dead. They tell stories. They gather.

The stones are just the stage. The people are the play.

So what happens when the people leave? The stage stays. The play fades. That is the question in Palau.

Our readingThis is the lens we use. It is not a claim from a source.

Core and edge

Core is where the government sits. Edge is the far corners.

Palau's core is new. The capital moved to Ngerulmud in October 2006. We follow the story from there out to the edges.

The through-line

Along this route, one thing keeps changing: what is left of the past gets smaller than what was lost.

A busy lagoon becomes ruins. A carved face loses its eyes and nose. A stone coffin sits behind a meeting house and nobody can say what it was for.

What holds it all together is not the stone. It is memory: stories, dances, proverbs and place names. Stone lasts. A place stays sacred only while people remember why.

Five stops, from the new capital to the far north

age and purpose

Modern country for every row: Palau. Every place has one status. Where the object is documented but its age or meaning is not, the status shows the part still in doubt.

The Rock Islands, then and now

Then

  • Villages built of stone
  • Burials in caves, and paintings on rock
  • People who lived off the lagoon's fish and shellfish
  • An estimated 4,000 to 6,000 people

Now

  • 445 islands, all listed as uninhabited
  • 52 marine lakes, more than at any other site in the world
  • A World Heritage site since 2012
  • Memory kept in legends, dances, proverbs and place names, by people whose families moved to the larger islands

Sources: UNESCO list 1386, UNESCO decision, Clark and Reepmeyer 2012 for the population estimate. The Rock Islands sit in Koror State, the same state as the old capital.

Sources disagree by centuries on when the islands emptied

Insider voices

Rurecherudel, a chief of Airai, tells the story in his own words (translated by Johnson) that the Badrulchau pillars were "the posts for the major bai for the gods." A bai is a Palauan meeting house. The date of this recording is not shown on the page.

Rita Olsudong, an archaeologist at Palau's Historic Preservation Office, put both Tet el Bad and the Yapese quarries on UNESCO's tentative list in 2004.

FactIn 1987, scholar Jo Anne Van Tilburg recorded 38 stone monoliths on Babeldaob and Oreor. 28 had human features.

The eyes and nose seen in drawings from the 1950s could no longer be made out.

Our readingMost of this loss is quiet. A face softens. A village empties. A reason is forgotten.

That is why the memory matters more than the stone.

Counter-narrative: the same event, told differently

UNESCO's listingThe villages were left in the 17th and 18th centuries, when people moved to larger islands.

A 2012 study (Clark and Reepmeyer)The islands were left during the Little Ice Age, a cooler and drier time. Less rain and fewer fish near shore may have played a part. They give no single date.

A summary of earlier radiocarbon workThe villages were left suddenly, in the early 15th century.

The Palauan tellingDescendants hold the islands in legends, dances, proverbs and place names. For Badrulchau, tradition says the gods' meeting house stood there. Archaeology has a charcoal date of AD 161 from under the pillars.

Our readingScience asks when and why. Memory holds where and who. Both are needed.

Hero insight

The biggest thing Palau lost from its sacred landscape is not a monument. It is a society.

An estimated 4,000 to 6,000 people once lived in stone villages on the Rock Islands. Today the islands are empty and listed by UNESCO. The memory survives in dances, proverbs and place names. The sources still disagree on when the people left.

What backs this up: the 4,000 to 6,000 estimate and the disputed date (Clark and Reepmeyer 2012); UNESCO's 17th to 18th century date and the memory that survives; 445 uninhabited islands, listed in 2012.

Sources and claims log

We logged 28 claims. 14 are verified. 2 are verified in part (one has a contested age). 1 is contested. 11 stayed unverified and are left off this page.

Photo credits

Verified means two independent sources or one primary source. Several rows rely on summaries of the original papers, which we did not read in full.

What we could not find

Coordinates for Badrulchau. The 2020 census tables (the file blocked us). A World Bank series. Any source written in Palauan. An account from Ngarchelong's own leaders.

Left out on purpose

One oral account describes a limestone ridge in Airai that was quarried. It has a single source and no date. It stays off the page until someone confirms it.

  1. Palau lost a society, not just a statue

    Follow five places from the new capital to the far north. The question is simple: what disappeared, and what survived?

  2. An empty lagoon

    These are the Rock Islands. UNESCO lists all 445 as uninhabited. An estimated 4,000 to 6,000 people once lived here.

  3. Why this matters

    A place is sacred because of what people do there. If the people leave, the stage stays and the play fades. Palau's capital is new. The oldest things sit at the edges.

  4. The route

    At each stop, what is left is smaller than what was lost. Start at the capital, go south to the Rock Islands, over to the stone money quarries, then far north to Ollei.

  5. Five places, one status each

    Documented, Contested or Inferred. We say plainly what each place has, and what is still in doubt.

  6. The Rock Islands, then and now

    Stone villages and thousands of people became 445 empty islands. The memory survived in stories and names.

  7. Nobody agrees when

    One source says the early 1400s. UNESCO says the 1600s and 1700s. A 2012 study says during the Little Ice Age. The gap is part of the story.

  8. The numbers

    Five figures, each with its source. The last one shows who lives in Palau today.

  9. Voices from inside Palau

    An Airai chief says the pillars were the posts of the gods' meeting house. An archaeologist at Palau's Historic Preservation Office put the stone coffin and the quarries forward for UNESCO.

  10. What the places look like

    The new capital, the pillars, a face worn almost smooth, and a stone coffin nobody can explain.

  11. The same event, told four ways

    UNESCO, a 2012 study, an older summary and the Palauan telling do not match. The science asks when and why. The memory holds where and who.

  12. The finding

    The biggest loss is a society. It survives in dances, proverbs and place names.

  13. Sources, and what we could not find

    28 claims logged. 11 unverified ones stay off the page. Photo credits are here too.
