How did the Waqf, a widespread Islamic historic institution in the non-Western world which promoted traditional building upkeep and maintenance systems, cope with the emerging architectural conservation understandings of the modern era? How did colonial transfers of knowledge, expertise and political considerations influence these systems? The present study explores these questions by examining the case of the Ottoman Waqf (Evkaf) institution in Cyprus. By collecting and analysing archival evidence on conservation projects, initiated during the British colonial period between 1878 and 1960, a model framework of initiation, authorisation and implementation processes of the upkeep of the Waqf maintained properties has been identified. This framework has been used to show the transitional role of the colonial influence at different stages, which finally led to the dissolution of the Waqf system's sustainable elements, and initiated the emergence of selective architectural conservation practices. By shifting the focus of conservation discourses to look specifically into the background dynamics of the institutional practice, a new argument has been developed. This revealed how heritage conservation practices are negotiated with the existing institutions and how they are transferred and/or transformed at different levels of institutional governance.
