Reinterpreting the Outstanding Universal Value of the Built Heritage of the Island of Mozambique: A Methodological Approach

This study proposes a methodological approach to reinterpret the Outstanding Universal Value (OUV) of the built heritage of the Island of Mozambique, inscribed on the UNESCO World Heritage List since 1991 under criteria IV and VI. In view of emerging challenges that threaten the heritage-making process—namely, progressive interventions in the built fabric—a methodology of interrelated reading is presented, grounded in a critical and participatory perspective centered on the local community. This methodological structure is operationalized through an interrelated reading model that combines architectural, constructive and intangible layers within a multi-scalar analytical matrix. This approach is based on three interdependent dimensions: (i) material and immaterial; (ii) symbolic and identity-related; and (iii) functional and sustainable. The theoretical model developed, supported by the participation of multiple stakeholders, demonstrates that small adaptations—compatible with cultural values and local actors’ interpretations—can strengthen the recognition of the value of built heritage and foster sustainable human development. Given the existing typological diversity, the study concludes that it is essential to adapt the model of OUV reinterpretation to each specific context, acknowledging the plurality of possible solutions and promoting a balanced integration of material and immaterial values without compromising existing cultural significance.
