1) Stucco in Monumental Context
Classical Ottoman stucco enriches domes, pendentives, mihrabs, and ceilings with lime plaster and painted surfaces. These layers carry historical evolution, repair traces, and material knowledge—not mere decoration. On monuments of outstanding value every intervention is internationally scrutinised; project rationale and documentation must be transparent.
Multiple repair layers often coexist; each must be assessed before any completion decision.
2) ICOMOS and Venice Charter
ICOMOS ethics and the Venice Charter reject restoration as a tool to return buildings to an idealised past. Articles 9 and 12 allow completion only with firm evidence—not conjecture. Conjectural reconstruction damages authenticity and blocks future scientific reading. Every intervention should pass tests of evidence, reversibility, and distinguishability.
Professional terminology should distinguish conservation from cosmetic “renewal” in public communication.
3) Evidence-Based Conservation
Evidence-based conservation combines survey, photo archives, material analysis, stratigraphy, and historical research. Pattern traces, pigment analysis, and mortar layers define what to preserve or consolidate. Claims of “original colour” or full pattern rebuild without a evidence chain should not stand. Digital survey provides before-and-after reference.
Historical photos and travel accounts support but never alone prove a completion design.
4) Limits of Conjectural Completion
Conjectural completion reproduces missing decoration without documentary support. The Venice Charter limits this sharply. Large-scale completion for visual unity may look tidy short term but reduces long-term scientific value. Professional practice favours stabilisation, cleaning, and local repair within conservation-restoration boundaries.
Restitution drawings visualise known data; building that design is a separate ethical decision.
5) Technical Interventions
Typical sequence: damage inventory → stabilisation → controlled cleaning → crack bridging → local completion → distinguishable finish. Acid, pressure water, and harsh abrasives harm stucco. Lime-plaster mixes preserve breathability; fast modern plasters may crack. New paint on original surfaces can be irreversible—reversible systems and test panels are preferred.
Hand craftsmanship and pattern analysis remain central on monumental stucco.
6) Authenticity and Public Perception
Visitors may mistake renewed surfaces for original fabric—an interpretation problem, not only a technical one. Ethical restoration marks distinguishable work clearly in drawings and reports. Monument decisions should follow interdisciplinary science, not political agenda or speculation.
Interpretation panels and digital guides help build public trust in transparent conservation.
7) Process, Board, and Supervision
Listed monuments require survey, restitution, and restoration approval by the regional conservation board. Site supervision ensures execution matches approved design. International good practice relies on joint reports from conservator, materials scientist, and architect—no work without written rationale.
Post-restoration monitoring plans catch problems before they require major re-intervention.
8) Conclusion
Stucco work on monuments like Selimiye Mosque demands ethical discipline alongside craftsmanship. Evidence-based conservation outweighs conjectural reconstruction under ICOMOS and Venice Charter logic. Heritage protection balances aesthetic expectation with scientific responsibility.
