Özet:

Sigacik,which is a district of the town of Seferihisar and is about five kilometers to the centre, lies in the southwest of Izmir. It is an important harbour town and has been subject to various public improvements from the 7th century B.C on. Rich ancient cities like Klazomenai, Lebedos, Myonnesos and Erythrai are located around it. As an export harbour, Sigacik served in the 19th century as a door that opened to the world. The Sigacik Castle and the buildings within the castle that belong to the Turkish period, namely the mosque, the mescit, the turbeh and the sadirvan, are the subjects of this study. These buildings that have come down to this day with some cahnges have been examined thoroughly using also plans and photographs. In addition, at the beginning of the study we have given the historical background of the town and information related to its importance as a trading harbour, and in the conclusion, we have made some suggestions on how these buildings can be passed down to next generations
