Kusadasi Castle, which dates back to the Ottoman era, and was built around 1523, is located on the strategically located Pigeon Island. This fortress was built with the aim of protecting the beach and avoiding any attacks from the sea side. The island is reached by a bridge, where you will find Kusadasi Castle, which contains a museum of special interest for those who want to understand Byzantine architecture, and the island also has a lot of beaches for swimming and recreation.
