The importance of preserving the architectural heritage is more meaningful when the building is preserved with its whole environment, with the other historical buildings around as a site protection. Preservation of historical monuments not only individually but also with their environments help the city regain its identity that it has lost. The Conservation Approach to Cultural Assets in Turkey has reached to its peek starting from 1985＇s through introducing the effects of the recent amendment on cultural heritage law and the impact of the EU integration process. The municipalities started to use this recent amendment on cultural heritage laws as a method of recovering their cities for the local identity searches. This paper will deal with the current challenges for conservation practice in Turkey, through introducing the effects of the recent amendment on cultural heritage law and the impact of the EU integration process, and examine some major promising conservation and renovation, rehabilitation projects continuing in Izmir the third biggest city of Turkey for which local solutions are being devised for problems of global context in the meaning of local identity searches for the city.展开更多
