Main image

Yoros Castle is a ruined medieval fortress on the Asian shore at the northern entrance to the Bosphorus in Istanbul Province, Turkey. The site occupies a headland that commands the channel where the Bosphorus opens into the Black Sea.

Remains include defensive walls and terraces on two promontory hills and traces of stone fortification work from Byzantine, Genoese and Ottoman periods. The castle functioned historically as a strategic stronghold controlling access to the strait and later as part of Genoese and Ottoman coastal defences.

The castle sits above the fishing village of Anadolu Kavağı, which is the normal arrival point for visitors who come by ferry from points along the Bosphorus. The site provides panoramic views of northbound maritime routes and the opposite European shore.

  • Viewpoint: The site offers commanding views over the Bosphorus Strait and the entrance to the Black Sea, making it a notable viewpoint for maritime traffic.

What to See #

  • Castle ruins: The castle ruins occupy a promontory above the confluence of the Bosphorus and the Black Sea and include defensive walls, cistern remains and terraces.
  • Anadolu Kavağı village: Anadolu Kavağı village at the castle's foot provides the usual access and services for visitors arriving by ferry from the Bosphorus.

How to Get to Yoros Castle #

Yoros Castle sits above the village of Anadolu Kavağı on Istanbul’s Asian shore at the Bosporus entrance. A convenient way to reach it is by ferry from the European side (Eminönü or Beşiktaş) or from Üsküdar - Şehir Hatları and some private operators run ferries to Anadolu Kavağı; the village is then a short uphill walk of about 10-20 minutes from the quay to the castle ruins. By car or taxi it’s reachable from central Istanbul (Taksim/Sultanahmet) via the Asian shoreline roads (follow routes toward Beykoz/Anadolu Kavağı); the drive is roughly 25-35 km depending on start point and traffic.

Tips for Visiting Yoros Castle #

  • Use the public ferry to Anadolu Kavağı (the village at the Bosphorus mouth) as your primary approach - the fortress sits a short, steep walk above the village and the ferry ride gives good views.
  • Visit late afternoon or at golden hour for the best panoramas of the Bosphorus entrance and the Black Sea; arriving early or late avoids the midday tour-group crowds that gather in the village.
  • Start your climb from the village center on the north side (near the quay) and follow the well-trodden path up to the ramparts-combine the castle walk with a seafood meal in Anadolu Kavağı to make the most of the trip.
