Cultural heritage management is an increasingly important concept in the world and in our country. The cultural heritage of a city consists of all the cultural layers that make up the city's past, and these layers feed each other. In a city like Istanbul that has been the capital of two empires, cultural heritage management has different challenges and advantages. In this study, the establishment and functioning structure of the Pantokrator Monastery dated back to Middle Byzantine Period and the Suleymaniye Complex built during the Ottoman Period, which are two structures that have an important place in the historical past of Istanbul, were compared as two public institutions and the similarities were made. In this context, in the light of these two institutions, the concept of urban memory was tried to be explained by emphasizing the importance of cultural continuity and urban archeology.
