Filyos Castle is an ancient castle structure located on a hill overlooking the Black Sea in the Filyos town of Zonguldak, consisting of Roman and Genoese period wall remains; admission is free.
Filyos Castle stands on a hill protruding into the sea, built upon the remains of the ancient city of Tios (Tieion). Large stone blocks were used in its construction. The majority of the walls standing today date back to the Genoese period, while some tower and foundation remains are from the Hellenistic-Roman period. Marble column fragments, inscribed slabs, stone sarcophagi, and brick tombs have also been unearthed on the castle hill's eastern side.
The castle was restored by the Ministry of Culture and Tourism in 2003, but visitor comments frequently mention a lack of maintenance: it is noted that weeds cover the ruins and there are many lizards. In contrast, its main attraction is the view. Those who climb to the castle get a clear view of Filyos beach and the Black Sea from above, and it is especially recommended to spend time here at sunset. One comment mentions a secret passage below the castle, said to extend from the sea to the castle, but this is not confirmed information, merely a local rumor.
The castle is integrated with the town center: one side of the ancient city faces Filyos, the other faces Filyos Port. Do not set your expectations too high for the historical texture; new findings are expected to emerge with ongoing excavations in the region. But as a short excursion, especially for those going to Filyos for the beach, climbing the castle is worth a half-hour break.

Guide's Note
Best Time to Visit
The castle is in an open area with little shade. In summer, it's more comfortable to go in the morning or late afternoon to avoid the midday heat. Visitors especially recommend sunset hours; the light illuminates both the sea and the stone ruins differently. In spring and autumn, the ruins are more clearly visible before the weeds grow too long.
How to Get There
The castle is in Filyos town center, close to the main road. It takes 7 minutes by minibus to the center, or 20 minutes on foot. Those coming from Çaycuma direction follow the Sefercik Neighborhood road; for those coming from Türkali side, the entrance is on the left side of the road after passing the central market. If you are going by car, remember that the entrance road has potholes, so slow down.
How Much Time to Allocate
The castle is a small area. 30-45 minutes is sufficient to explore the wall ruins, tower remains, and the section with marble fragments. You can allocate a little more time for taking photos. If planned with Filyos beach, it makes for a half-day trip.
Route Suggestion
Most visitors to Filyos combine the castle with a beach trip. It's a logical sequence to first climb to the castle in the morning or afternoon to see the view and the ruins, then descend and spend time on the beach. One comment states that the beach in front of the castle is one of the most suitable and cleanest spots for swimming.
Things to Pay Attention To
Two issues frequently mentioned in visitor comments are lack of maintenance and lizards. It is noted that weeds cover the ruins and there is a high density of lizards among the stones; this note is for those who might be bothered by this. Additionally, a few comments complain about the attitude of the security guard towards visitors. Such experiences can vary from person to person. Do not set your expectations too high regarding the historical remains; more findings are expected to emerge with ongoing excavations in the region.
Photo Spots
The part of the castle facing the sea offers the best shot, showing the entire Filyos beach and the Black Sea. Photos taken from between the castle walls capture the stone texture and the sea in the background together. At sunset, the light hitting the stones is the most suitable moment for photography.
Historical Layers of the Castle
The region was known as Tios (Tieion) in ancient times, a port city. The first settlement of the castle dates back to the Hellenistic and Roman periods; most of the walls standing today are from the Genoese period. Genoese merchants built such strategic castles to protect Black Sea trade routes. During the Ottoman period, it largely lost its military function, but its walls and bastions have survived to the present day.
