it needs to be stated that in almost half of Sur, apart from the destroyed buildings, the original street fabric and the insular-parcel integrity have been irreparably lost. Together with the forced exodus and forced expropriation, it leads to the eradication of the traditional-social life, trade forms and urban social memory, developed over thousands of years, the change of propriety, the change of the demographic structure and the interruption of cultural continuity. The ongoing “Tigris Valley Project” is another big threat to the Word Heritage Site Diyarbakir outside of the fortress, which should not be underestimated. If all planning of the Turkish government would be implemented, the World Heritage Site of Diyarbakir would completely lose its core values and its uniqueness. The result would be a new old city with a completely new population, which has no relation to the cultural heritage of Diyarbakir, and a big commercialized area serving only big investments and profit, while erasing the local culture.
