Yoros Genoese Castle is located on the Asian side of Istanbul, above the fishing village of Anadolu Kavagi, at the point where the Bosphorus opens into the Black Sea. The ruins stand on elevated ground, offering clear views of the strait, the coastal slopes, and passing ships. Thanks to this position, the site has long held defensive and observation importance.

Although the castle is often called Genoese, its history began earlier. Fortifications on this site existed as far back as the Byzantine period, and in later centuries they were used by various forces seeking to control the sea route between the Bosphorus and the Black Sea. The name is associated with the Genoese, who indeed played an important role in the life of this area during the Middle Ages.

Today, sections of stone walls, towers, and gates built into the hillside terrain have survived. This is not a restored museum complex, but rather true historical ruins, so people come here primarily for the panoramic views and the atmosphere of an old frontier fortress. A visit is usually combined with a walk around Anadolu Kavagi and a trip to the northern part of the Bosphorus.

Yoros is of interest to those who want to see a lesser-known side of Istanbul beyond the city center. It combines military history, views of a strategic stretch of the strait, and the calm coastal setting of a small village. The site is well suited for a short half-day outing, especially if you want to combine ruins, a seascape, and a walk away from dense urban development.
