This thesis aims to shed light on the reappearance of defensive concern, its materialization and its evolution in Western and Central Anatolia in the Early First Millennium BC. (10th-6th c.). The area under consideration includes Phrygia, the Halys bend, Caria, Lydia, Ionia, Aeolis and the Troad. This study focuses primarily on the various fortification methods used during this period. By examining the main architectural features of defensive walls (building techniques, defensive components), this study seeks to determine how these new constructions inherited from the Anatolian architectural tradition and how their designers contributed to make it evolve by adopting and transforming some of its principles. The construction of a wall, because it involved many actors, was also major social phenomenon. Iron Age fortifications sometimes bear witness to the history of the various populations who built and perfected them. Hence, beyond archaeological considerations, this study also aims to place the construction of fortifications in the military context of the tumultuous pre-classical Anatolia. It also attempts to evaluate the impact of such a construction project on the sociopolitical history of Anatolian Iron Age populations: Greeks, Lydians, Phrygians and Carians.
