Abstract

During the World War II, traditional trenches and bastions were replaced by fortification structures made of concrete, defined as Pillboxes. Defense lines consisting of pillboxes were built in many parts of Europe. State of the Republic of Turkey Although it was not directly involved in the World War II, he took important measures for defense purposes and built fortification lines consisting of bunkers named after Marshal Fevzi Çakmak. With the Cakmak Line, it is primarily aimed to counter possible attacks against Istanbul. In this direction, the most important elements of the line were built in the west of Istanbul, in the Çatalca and Büyükçekmece regions against the attacks that may come from Thrace. During the field studies, it is understood that the Çakmak Line includes a defense line against the possibility of landing on the Anatolian side of Istanbul over the Black Sea. Within the scope of this article, field studies were conducted to Decipher the shelters and document their current status on the 37-kilometer coastline between Anatolian Lighthouse, Riva and Sile in the north of the Anatolian Side of Istanbul, and 56 pillboxes were identified.Suggestions and evaluations have been made by considering some examples in the world in the context of protecting the detected pillboxes as military architectural heritage, integrating with the urban identity and raising awareness.
