What becomes visible when we read a place through its relationships?

the question beneath the work

Before we ask how to preserve a place, we ask how to know it.

Heritage thinking has expanded well beyond monuments and buildings, into practice, memory, use, care, and continuity. The instruments have not kept pace: the analytical and institutional processes that inform decisions still act most readily on what is materially bounded, documented, officially recognized, and procedurally legible.

The difficulty is therefore not only how to attend to relationships. It is how material and immaterial, unofficial and official forms of continuity can be made visible within one comparable analytic field—before priorities, boundaries, and funding decisions are fixed.

method

The Four-Quadrant Framework

A place is more than a collection of things; it can be read as a field of relationships. The Four-Quadrant Framework is the instrument that makes that field analytically legible. Developed as a methodological contribution of doctoral research in heritage preservation and empirically applied in post-earthquake Antakya, it positions documented acts across two intersecting continua and reads how their distribution holds, thins, or shifts over time.

time material immaterial unofficial official tangibility authority documented act — a position, not a category
Both axes are continuous. The four fields are regions of accumulation, not four types of heritage. Points shown illustrate positioning; they are not case data.

The unit of analysis is the documented act—a specific, evidenced act positioned within the field, rather than a whole building, community, or ritual sorted into a box. In practice this means observing, documenting, mapping, and interpreting acts as they take shape across a place and over time.

What the method produces is not a label but a distribution: a field that can be read, compared across sites, and re-read across time.

Density

Where documented acts concentrate, and what that concentration is made of.

Absence

Where the field is thin or empty—and whether that is a condition, a gap in evidence, or a limit of recognition.

Dependency

Where one form of continuity relies on another to remain legible or supported.

Temporal shift

How the distribution thickens, thins, or migrates between one moment and the next.

longitudinal comparative research

Antakya, after rupture

The empirical application of the Four-Quadrant Framework: two damaged sacred sites in post-earthquake Antakya, read comparatively and across time through documented acts.

Location

Post-earthquake Antakya, Türkiye

Study window

February 2023 – early 2026

Fieldwork

August 2023
June 2024

Case sites

Habib-i Neccar Mosque
St. Paul Greek Orthodox Church

Research condition

Two sacred sites damaged in the same event, entering recovery under different institutional and community conditions—while access, use, and forms of custody continued to change.

Method

Documented acts drawn from field observation, spatial and photographic documentation, and institutional records were positioned across both continua and read serially across the study window.

Finding

Across both sites, the comparison revealed a structured dependency between official heritage action and forms of community-carried continuity that precede it, persist through it, and are not produced by it.

application

From diagnosis to practice.

The Framework was developed as a research instrument, but its function is diagnostic—which means it can enter a project wherever decisions about scope, priority, and care are being made.

01 · scoping

Preliminary assessment

Establishing what is already present in the field before priorities, boundaries, and funding decisions are fixed.

02 · design

Planning & design

Testing whether different forms of continuity are entering the project field, or only the ones that are easiest to document.

03 · monitoring

Implementation

Tracking how the distribution of documented acts and forms of care changes as intervention proceeds.

04 · evaluation

Post-project review

Assessing what was recognized, sustained, displaced, or left outside the intervention once it concluded.

These are application capacities of the method. Depending on the question and context, they can take the form of research commissions, advisory work, mapping studies, workshops and facilitated dialogue, collaborative research, or public and exhibition translation.

about

Dr. Çiçek Karataş Yıldırım

Architect, architectural historian, and heritage researcher, based in Chicago.

She developed the Four-Quadrant Framework through her doctoral research and applied it through longitudinal comparative research in post-earthquake Antakya—work informed by a longer relationship to the city. She founded iz(trace) to carry that research into applied, institutional, spatial, and public contexts.

iz is the Turkish word for trace: a partial, situated point of entry from which a field of relations can be read. It names where observation begins, not the method itself.

work with iz(trace)

Bring the method to a real decision.

iz(trace) works with heritage projects at moments of change—when a place is being assessed, restored, reopened, reprogrammed, or otherwise transformed, and when decision-making needs a fuller view than the most readily documented evidence can provide. The Four-Quadrant Framework helps establish what forms of continuity are already active, which are institutionally visible, and what may otherwise remain outside the project field.

The Framework diagnoses; it does not prescribe an outcome. In an advisory engagement, iz(trace) uses its diagnostic findings to support context-specific decisions, discussion, and project development.

What an engagement looks like
01 — Define the question

Identify the site, decision, programme, transition, or condition that needs to be understood.

02 — Build the evidence field

Assemble relevant spatial observations, existing documentation, institutional records, community-generated material, and other traceable evidence appropriate to the question.

03 — Map and interpret

Position documented acts using the Framework’s stated criteria and read the resulting gaps, concentrations, dependencies, and temporal shifts.

04 — Translate the diagnosis

Turn the analytical findings into a project-specific form that can support discussion, planning, monitoring, evaluation, or further project development.

Engagements are scoped to the question, the evidence available, and the stage of the project.

Diagnostic & scoping studies

Establishing the field of documented acts around a site or project, and reading what its distribution reveals, ahead of decisions.

Typical outputsevidence register · diagnostic mapping · concise analytical findings

Advisory & relational mapping

Applying the Framework to an ongoing project to test what is entering the field and what is falling outside it.

Typical outputscomparative or temporal mapping · identified gaps and dependencies · decision brief

Workshops & facilitated dialogue

Working with teams, institutions, and communities to read a place together through evidence rather than assumption.

Typical outputsfacilitated evidence session · participant readings · iz(trace) analytical synthesis

Research, public & exhibition collaborations

Translating relational analysis into publications, teaching, exhibitions, and other public-facing forms.

Typical outputsresearch-derived visual, spatial, editorial, or public translation

Depending on scope, a commission may result in a mapped analytical field, evidence register, concise report, decision brief, workshop synthesis, or monitoring update.

Potential collaborators include cultural and heritage institutions, municipalities and public agencies, NGOs and foundations, archives, community organizations, researchers and universities, and design teams.
