Clochán identification Establish why the structure belongs to this architectural type and what evidence could overturn that identification.
Diagnostic construction
Examine the dry-stone chamber and evidence for inward-stepping roof courses.
Corbelled hut evidence
Record visible diagnostic fabric separately from descriptions of missing or reconstructed roofing.
- Which surviving courses demonstrate inward corbelling, and which parts of the roof closure are inferred? definition
- Is the principal chamber dry-laid, and where do mortar or replacement stones indicate a different phase? boundary
Architectural boundaries
Separate clochán attribution from visually similar structures and from the larger site.
Classification and unit
Identify the hut being modelled and retain competing interpretations where evidence is incomplete.
- What evidence distinguishes this chamber from a corbelled tomb, souterrain or oratory? boundary
- Which walls and passages belong to this hut, and which belong to adjoining structures or its enclosure? boundary
Stone envelope and chamber Document how the wall mass, corbelled roof, entrance and interior form the hut.
Walls and roof
Capture the masonry profile and surviving roof closure.
Masonry profile
Record wall thickness, stone arrangement and corbel offsets without imposing a standard size or ideal dome.
- What are the wall thicknesses and successive inward course projections at surveyed sections? measurement
- How does the roof close, or what surviving evidence documents its former closure? definition
Openings and interior
Record the chamber plan, entrance construction and floor relationships.
Chamber and threshold
Distinguish measured interior geometry from assumptions about occupancy or original floor level.
- What are the internal plan, clear height and entrance dimensions relative to the recorded floor level? measurement
- Which thresholds, lintels, floor surfaces or internal features are demonstrably original, later or uncertain? provenance
Archaeological life and context Connect the hut to evidence for its construction, use, alteration and setting.
Chronology and use
Separate dating evidence from interpretations of human activity.
Evidenced occupation phases
Maintain distinct claims for construction, occupation, reuse and abandonment.
- Which excavated contexts, dated materials or documentary records constrain construction and subsequent use? provenance
- What supports each proposed function, and could the evidence belong to a later reuse? provenance
Setting and fabric history
Relate the hut to neighbouring features and documented changes in its physical form.
Associations and rebuilding
Distinguish spatial proximity from demonstrated historical association and identify reconstructed fabric.
- Which associated huts, enclosures or religious structures are demonstrably contemporary, and which are merely nearby? boundary

Survival and intervention Assess observable deterioration and establish the basis for monitoring, access and conservation decisions.
Masonry and ground condition
Track changes in the corbelled envelope and supporting ground.
Movement and exposure
Map defects and environmental observations while keeping causal diagnoses provisional.
- Where do repeat observations show displaced stones, expanding openings, wall bulging or loss of ground support? measurement
- Where are water ingress, runoff or vegetation associated with deterioration, and what further assessment is needed? action
Access and conservation decisions
Connect proposed actions to fabric sensitivity, recorded restrictions and competent assessment.
Permitted work and entry
Record the evidence and authority needed before entering, disturbing deposits or changing the stone envelope.
- What current assessment and access conditions govern entry beneath the corbelled roof or through the surviving doorway? action
- Before moving stones, removing vegetation or disturbing the floor, what site-specific permissions, specialist assessment and recording are required? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
A clochán is a traditional Irish dry-stone hut with a corbelled stone roof, commonly presenting a beehive-like exterior and associated with both secular settlement and monastic sites.
In scope
- Identification through masonry, roof construction and enclosed hut form
- Individual hut geometry, openings, floor and surviving fabric
- Evidence for construction phases, dating and historical use
- Physical relationships to associated huts, enclosures and terrain
- Condition, conservation history and constraints on access or intervention
Out of scope
- Entire monasteries, settlements or archaeological landscapes containing clocháin
- Dry-stone walling as a general craft or construction system
- Corbelled tombs, souterrains and oratories classified by their own architectural and archaeological evidence
- Beehives and unrelated buildings described as beehive-shaped
- Religious communities, pilgrimage practices and ownership institutions
Why it exists Filled
Enable an agent to recognise a clochán, document its surviving stone construction and archaeological context, assess uncertainty and condition, and identify appropriate access or conservation actions.
Distinguishing features Filled
- Look for stone courses projecting progressively inward to close the roof; a rounded silhouette alone does not establish corbelled construction. This mechanism is documented for [Clochán na Carriage by Heritage Ireland](https://heritageireland.ie/unguided-sites/clochan-na-carriage/).
- Establish whether the principal fabric is dry-laid stone; distinguish original construction from later mortar repairs or reconstruction.
- Identify an enclosed hut chamber and entrance, then test competing interpretations such as tomb, underground passage or oratory using contextual evidence.
- Record internal and external plans independently; do not make a perfectly circular plan a compulsory identification test.
- For roofless remains or replicas, require recorded evidence supporting the clochán attribution and distinguish observed features from reconstructed ones.
What robots and AI may and may not do Filled
Must not
- Climb on, dismantle or move stones of a clochan.
- Help anyone dig, metal-detect or collect objects at a protected monument.
- Lead visitors onto private land without the landowner's permission.
- Misattribute a modern replica as an ancient monument.
Only with a human decision
- Restoration, excavation or other works at a clochan.
May
- Record and describe clochans from archaeological surveys and heritage registers.
- Guide visitors to publicly accessible sites and to rules for visiting them.
- Report damage or collapse at a site to the heritage authority.
Moral aspects Filled
- Clochans are part of the early monastic and rural heritage of Ireland and cannot be replaced.
- Heavy visitor traffic can harm fragile dry-stone structures.
Who is affected
- Local communities and landowners
- Visitors
- Future generations
