This project arises from the idea of reevaluation of the historical environments, regenerating the previous value of historical asset and the necessity of reinstalling this value to itself. Especially, at the present day, being got away from the concept of conservation by freezing and the idea of perpetuating by fulfilling the requirements of era is becoming widespread in this context besides the city courts harboring functions which have not lost their validity, monuments and their areas which have lost their original functions are also discussed. Conservation and correct reflection of historical accumulation will also be the part of development. This can be only possible by discussing the peripheral and social sustainability by all its aspects in conservation context. In this scope the concept of reevaluation of the historical environments and the reasons of these studies are tried to be introduced and the loss of meaning in these areas are tried to be drew attention to.
