Perched above the fishing village of Anadolu Kavağı, Yoros Castle gazes silently over the northern mouth of the Bosphorus—a windswept vantage point where empires once clashed, and where the sea still whispers secrets.

An Overlooked Gem of the Northern Bosphorus
Few visitors to Istanbul make it this far north. Even fewer know that nestled atop a forested ridge, just a short hike above Anadolu Kavağı, lies a castle that once played a vital role in controlling one of the most contested waterways in the world. Yoros Castle is not only a place of panoramic views—it’s a palimpsest of civilizations.
This is not the curated elegance of a museum or a polished Ottoman courtyard. This is a place where time lingers in stone. Where moss creeps over history. And where the roar of the Black Sea is felt as much as heard.
Etymology: Why "Yoros"?
The name “Yoros” is thought to derive from the Greek word “oros”, meaning “mountain” or “hill,” fitting for a fortress perched high above the water. Throughout the centuries, it has also been known as the Genoese Castle, Kavak Fortress, and simply the castle by the strait.
This multiplicity of names mirrors the castle’s layered history: Byzantine, Genoese, Ottoman—and long before them, possibly even Phoenician or Hellenistic settlements once stood here.
Strategic Importance Through the Ages
Yoros Castle was built by the Byzantines, likely in the 13th century, to guard the northern entrance to the Bosphorus. This narrow waterway—barely two kilometers wide at this point—was a crucial maritime corridor linking the Black Sea to the Mediterranean, and by extension, Europe to Asia.
Later, the Genoese took over and fortified the structure further, using it as a base to control trade and levy tolls on passing ships. When the Ottomans rose to power, they understood the castle’s value immediately and made it part of their defensive network.
This stretch of water has seen Byzantine emperors, Genoese traders, Ottoman sultans, and Russian warships sail through—and Yoros has witnessed it all, silently and steadfastly.
Architecture & Ruins
Today, what remains of Yoros Castle are mostly two surviving towers, parts of the outer walls, and a commanding gatehouse. Though much of it has succumbed to time and erosion, several fascinating elements survive:
- Byzantine stonework with subtle religious carvings
- Ceneviz (Genoese) symbols faintly etched into the walls
- Ottoman-era repairs and additions visible in the brick patterns
Some legends even speak of underground tunnels that once reached the sea—now collapsed or lost to vegetation.
Legends, Myths & Local Stories
Like many ancient sites overlooking deep waters, Yoros Castle is wrapped in legend. Some locals whisper of secret tunnels that once connected the fortress to the sea, used for escape or smuggling—though none have been formally discovered.
Others say the hilltop where the castle stands was once sacred ground for the Amazons, the legendary warrior women of Anatolia. There are even folk tales suggesting that an ancient oracle once resided here, watching the sea and interpreting omens from the wind and waves.
Though these stories may not appear in history books, they are kept alive by the villagers of Anadolu Kavağı, adding a mystical air to every broken stone and windswept arch.
The View: A Meeting of Waters
Climb just a little higher, and you’ll reach the edge of the world—or so it feels. From the hilltop beside the ruins, your eyes stretch across the Bosphorus, into the Black Sea, and back down the strait toward Istanbul.
On a clear day, you might spot the Rumeli Lighthouse across the water, or even ships lined up like patient soldiers, waiting for their turn to pass. Sunset here is ethereal—the light turns golden, the wind stills, and for a moment, the centuries fall silent.
Getting There & What to Expect
Reaching Yoros Castle is not just about arrival—it’s about the journey itself, especially if you start from Eminönü, in the heart of old Istanbul.
From Eminönü by Ferry (The Scenic Route)
Make your way to the Eminönü Pier and board a Şehir Hatları Bosphorus ferry bound for Anadolu Kavağı, the northernmost stop on the Bosphorus route. The ferry ride takes about 1 hour and 15 minutes, passing by palaces, mosques, wooden mansions, and sleepy fishing villages that slowly peel back the layers of the city.
Sit on the right side of the boat for the best views as you head north toward the mouth of the Black Sea.
Once you arrive at the Anadolu Kavağı ferry dock, follow the signs (or ask a friendly villager) for “Yoros Kalesi.” The castle is about a 15 to 20-minute uphill walk from the pier. The path winds through narrow village lanes lined with flowered windows, tea gardens, and the occasional smell of grilled fish wafting from a terrace.
It’s not a difficult hike, but comfortable shoes and a bottle of water are highly recommended—especially in warmer months. Along the way, you’ll likely encounter cats lounging on stone steps, elderly locals sipping tea, and vendors selling fresh fruit or corn on the cob.
There is no entrance fee, and the site is generally open to the public, though some sections may be cordoned off for safety reasons, as the ruins are unrestored and exposed to the elements.
Alternative: Arriving by Road
For those who prefer to go by land, it’s possible to drive or take public transport to the Asian side and continue north to Beykoz, then onward to Anadolu Kavağı. However, roads get narrow and congested near the village, and parking is limited—especially on weekends.
Still, nothing beats arriving by sea. The combination of a slow ferry ride, a charming uphill walk, and the reward of panoramic views from the ruins makes this one of the most rewarding day trips Istanbul has to offer.
Eat, Drink, and Soak It All In
Before or after your castle visit, spend some time in Anadolu Kavağı itself. The village is known for its charming fish restaurants, where you can enjoy fresh Black Sea anchovies, grilled mackerel, or a classic rakı-balık experience right by the water.
On the way up or down from the castle, several tea gardens and small cafés offer lovely views and quiet corners to rest. Try a glass of çay, a bite of börek, and take in the slow rhythm of the village—a stark contrast to the city below.
