A stone ancestor figure stands above the Pacific, but the view contains more than a monumental head. It belongs to a cultural landscape shaped by Rapa Nui sculptors, ceremony, settlement and generations of descendants. Looking carefully means knowing the difference between a moai, an ahu, a quarry, a reconstructed platform and an archaeological hypothesis.
These 100 terms are grouped into ten clear subjects with a simple definition, a useful collocation and an original example for each entry. This reader-friendly guide helps explain Rapa Nui archaeology without inventing dates, asserting one transport technique for every moai or reducing the island’s later history to an oversimplified collapse story.
The UNESCO World Heritage entry for Rapa Nui National Park describes an estimated 900 sculptures, more than 300 ceremonial platforms, Rano Raraku quarrying and varied settlement and rock-art features. The property was inscribed in 1995. The formal World Heritage site is approximately 6,666 hectares and is not identical to the whole island. Some monuments have undergone researched restoration or re-erection, and current access rules must always be respected.

79. Ecological hypothesis — A proposed explanation involving environmental pressures. Natural pairing: ecological-change hypothesis. Original example: A hypothesis about resource loss needs careful evidential testing.
80. Contested interpretation — An explanation still debated or disputed by researchers. Natural pairing: contested historical interpretation. Original example: A single collapse story can obscure other perspectives and evidence.
Monitoring, restoration and appropriate access
Distinguish ancient fabric from modern conservation, and treat park regulations as current rather than guessed.
81. Protected property — Land recognised under a formal protection framework. Natural pairing: UNESCO protected property. Original example: Park protection applies to a mapped area.
82. Boundary map — A diagram showing the extent of a designated property. Natural pairing: World Heritage boundary map. Original example: The park property should not be confused with the entire island.

Source literacy and careful archaeological conclusions
Conclude by naming your sources and openly stating what they have not established.
91. Archaeological catalogue — A structured description of a monument or finding. Natural pairing: archaeological catalogue record. Original example: The catalogue distinguishes one moai from another.
92. Provenance — Documented origin and history of an artefact. Natural pairing: verified provenance. Original example: An object’s provenance should not be guessed from appearance.

Four useful archaeology exercises
Practice A: Moai versus ahu.
Find one documented site photograph and describe the statue and its ceremonial platform as two related but distinct structures.
Practice B: Carving without invention.
Describe an unfinished moai at Rano Raraku. Explain how tool marks and attachment to bedrock can inform a carving sequence, but cannot by themselves reveal why work stopped.
Practice C: An experiment is not a time machine.
A replica moves using an experimental method. Explain what this shows about physical feasibility and why additional archaeological evidence is needed for a historical claim.
Practice D: Respect the restoration record.
Identify the difference between a surviving ancient component, excavated material and a moai re-erected through modern conservation. Write a caption naming that difference.
Frequently asked questions
What is a moai?
A monumental stone sculpture associated with the Rapa Nui tradition of ancestral representation.
What is an ahu?
A ceremonial platform or complex, sometimes associated with rows of standing moai.
Where were many statues shaped?
Rano Raraku is a major quarry containing sculptures at various stages of completion.
Were all moai carved as heads without bodies?
No. Many have sculpted torsos and other features, some partly obscured by accumulated soil.
What is a pukao?
A red stone upper element placed on certain moai; precise interpretation should be source-based.
Does every moai face the same way?
No universal statement is sound; orientation depends on the particular site.
How were the statues moved?
Researchers have proposed and tested different methods. Evidence must be assessed before treating any one explanation as universal.
When was the park inscribed by UNESCO?
In 1995.
Is the island’s history explained entirely by resource collapse?
No. Historical explanations are debated and must also address later contact, disease, enslavement and community resilience.
Can tourists walk among all monuments?
No general entitlement should be assumed. Follow current park rules and community guidance.

Describe one monument well
Find a credited image and write three sentences. Name the specific place if verified, describe the stone feature you can see, and cite an authoritative source for anything you infer about carving, chronology or purpose. If an attribution is not known, say so. Precision can make a heritage story more interesting, not less.
