What it is Filled
A parecclesion is a subsidiary chapel attached to or forming part of a Byzantine church, often used for burial and commemorative worship.
In scope
- Identification as a subsidiary chapel in a Greek or Byzantine church context
- Chapel extent, entrances and connections to the principal church
- Construction phases and alterations affecting the chapel's identity
- Evidence of dedication, worship, burial and commemoration
- Location and condition of chapel fabric, tomb settings and decoration
- Present use, access and constraints on intervention
Out of scope
- The complete architectural model of the principal church or monastery
- The religious institution, congregation or administrative jurisdiction
- Biographies of patrons, clergy and people commemorated
- Detailed models of individual artworks, inscriptions or human remains
- General Orthodox liturgy and theological doctrine
- Municipal boundaries and the surrounding settlement
Why it exists Filled
Enable an agent to recognise a parecclesion, assess its surviving chapel space and evidence of use, and identify appropriate access, documentation or conservation actions.
Distinguishing features Filled
- Identification depends on evidence that the space is a subsidiary chapel associated with a principal church; lateral position alone does not distinguish it from an aisle or passage. Terminological anchor: [Getty Art & Architecture Thesaurus](https://www.getty.edu/vow/AATFullDisplay?find=&logic=AND¬e=&page=1&subjectid=300259480).
- Distinguish the chapel from a narthex or service chamber by examining its documented designation, spatial arrangement and evidence of devotional use.
- Funerary use is a possible function, not a mandatory recognition test: a university architectural reference describes varied functions and identifies funerary examples at Chora and Pammakaristos. See [Columbia University, Restoring Byzantium](https://www.columbia.edu/cu/wallach/exhibitions/Byzantium/html/building_history.html).
- Distinguish the parecclesion from the entire church complex by recording its own extent, access and architectural relationship to the principal worship space.
- Treat a lost altar, changed entrance or later conversion as evidence to assess alongside the historical record, rather than automatically excluding the space from this type.

- Flag threats to chapel fabric, tomb settings or decoration for specialist assessment.
- Determine documented access and intervention requirements before visiting, surveying or proposing work.
Hazards and failure modes required Filled
- Damp, earthquakes and poor restoration can destroy wall paintings.
- Theft of icons and fittings from heritage churches.
Standards and interfaces required Filled
- The Venice Charter, adopted by the Second International Congress of Architects and Technicians of Historic Monuments in 1964 and upheld by the International Council on Monuments and Sites, provides conservation principles applicable to historic chapels.
Context of use required Filled

Open questions
- Does the registry intend the broader Greek subsidiary-chapel meaning or a narrower Byzantine funerary-chapel meaning?
- Which criteria distinguish a parecclesion from other side chapels when historical terminology and surviving architecture disagree?
- Should physically detached subsidiary chapels qualify, and which authoritative architectural usage supports that boundary?
- Which comparative examples establish variation in plan, position and function without making Chora or Pammakaristos the universal template?
- Does an existing Vercy church or chapel model already own this concept, requiring a registry link or a narrower extension instead of a separate publication?
