Climate change is currently one of the most essential and fastest-growing threats to people and their heritage around the world. Heritage assets and sites are vulnerable to the impacts of climate change due to their age and being in constant interaction with the environment and weathering processes. In particular, historic coastal settlements are highly vulnerable to climate change effects due to their proximity to the sea, which may lead to coastal erosion, changing sea levels, abrupt changes in air temperatures, storms and floods that may damage or even lead to the disappearance of these areas. Thus, developing resilience through tailor-made conservation strategies for historic coastal settlements is crucial to transfer them to future generations. In this context, this study discusses the effects of climate change through the example of Kuşadası Citadel, a historical coastal settlement located in the Mediterranean Basin, which is expected to be highly vulnerable to climate change. The study identified the potential conservation problems that may arise from the effects of climate change on the listed and ‘façade to be conserved’ immovable cultural assets of the Kuşadası Citadel. Accordingly, the study has developed its method. Area-specific climate change impacts were determined, vulnerability and risk analyses were performed, and administrative, site and building-scale conservation strategies were developed. In conclusion, strategies have been developed for the Kuşadası Citadel, which is highly vulnerable to the effects of climate change, to protect it from these effects at different scales. It is an example of coastal settlement research in the context of climate change adaptation and gives guidance for local-scale conservation efforts.
