Cultural sites, historical buildings and monuments have become an essential part of the living areas. They are defined as memory of the area and must be preserved. UNESCO World Heritage Convention has studies about conservation since 1972 as World Heritage Areas which have outstanding universal value for humanity. Nowadays if an area is accepted as World Heritage Site, a Management Plan Guide would be a necessity. Although the Management Plan concept takes place in Turkish legislation the disputes are still going on because of lack of manual. Through the continuing debates this study aims to develop a Management Plan Guide for efficient conservation of World Heritage Areas. In the study the heritage and management are considered as the main concern. A Management Plan Guide constituted via advisory bodies‟ recommendations for guiding the conservation areas. Additionally, different management plan cases are held from all around the World and Turkey and these examples helped to find out the importance of the monitoring phase in a management plan. In the case of Pergamon there is already an existing Management Plan since 2017. Due to examined cases and studies an alternative guide was developed for the next Management Plan according to the legal system in Turkey. Key words: world heritage, management plan, outstanding universal value, Pergamon.
