The city of Bursa has experienced cultural heritage conservation works as being one of the world heritage sites in Turkey. The city's historical identity, which includes various types of cultural assets from different periods of civilizations, has been subjected to challenges such as immigration and squatting while attempting to stay up with new conservation legislation rules, since the 1970s. Meanwhile, Bursa's local authorities have emerged as basic actors in the coordination of development activities involving many types of stakeholders in the conservation of cultural assets in both rural and urban historic districts. However, the urban transformation activities that have resulted from the new legislative requirements enacted since the early 2000s have posed a threat to the continuity of the typical texture of the historic neighborhoods. The purpose of this study is to show how the Ottoman identity of Bursa has resisted the heterogeneity in the conservation acts in Türkiye. The conservation techniques and efforts that have been implemented, as well as the conservation decisions, are documented chronologically to ensure the long-term viability of its multi-layered historic structure. Within the concept of the study, the parallelism between conservation decisions and applications is explored, along with an evaluation of the effects of legal variability on this issue. As a result, the relevance of the historic urban identity of Bursa is emphasized within the context of modern policies created in tandem with modifications to the conservation legislation in Türkiye.
