The Movement of Cittaslow was born in Italy in 1999 and it has been adopted as a conservation policy. The philosophy of this movement; is based on rejecting a life that is not original, devoid of communication and focuses only on consumption. It invites people to maintain their original and traditional life habits with a modern approach. It involves inclusive policies, for all natural and cultural elements from the past that have conservation value. It particularly encourages local production. Gökçeada, which is selected as a study area is Turkey’s largest island and, it is located in the northeastern of the Aegean Sea. In addition to important natural landscape features, it also has a remarkable cultural richness. Examples of traditional Greek architecture and local products (wine, olive oil) are important cultural elements of the island that should be protected. Gökçeada was joined in the international slow city network in 2011. It is the first and only island in the network. In this study, the contribution of the slow city movement to the sustainability of cultural landscape features was investigated in the case of Gökçeada. For this purpose, the relevant criteria in the slow city manifesto were examined. With the observations and investigations carried out in-situ, the proficiency of the projects or activities on conservation of cultural landscapes, from achieving the status of the slow city to today were discussed. At the end of the study; it was found that the title of the slow city was not as effective as expected in Gökçeada. In addition, in order to minimize the destructive effects of the rapidly developing tourism activities on the cultural landscape elements, various suggestions have been made within the framework of the slow city approach.
