2. The fortress, built in 1508 by Beyazıt in the form of a rectangle, creates a spectacular view with 6 towers and three adjacent ditches. The castle, which was built as a seaside building at the time of its first construction, was kept inside by filling the sea from time to time. The International Cesme Music Competition, which is celebrated every year at the historical site, and the Çesme Festival between July 2-7 are organized. When you visit Kaley, you can see the sculpture with the lion beside the Great Turkish Commander Captain-Derya Algeria Hasan Pasha in front of the castle.
