Karadeniz Ereğli Museum

The museum is in a historical building, the former Halil Paşa Mansion. The Halil Pasha Mansion was built in the late 19th century during the rule of Sultan Abdulhamit II. Erected on the foundation of an old church, the mansion is decorated with ancient spolia collected from Roman-era structures. In addition to archaeological remains found in Black Sea Ereğli and its environs, the museum exhibits ethnographic artifacts unique to the region.

Zonguldak Mining Museum

Mining in Zonguldak started in the 1880s. This area is used as a mining training centre today. The training centre has an underground opening of about a kilometre and all mining units can be viewed, except for the underground well. In the museum complex –very close to the city centre – there is also a multipurpose hall, an exhibition hall and a cafeteria, where information about the museum is provided.

Gazi Alemdar Ship Museum

The Alemdar is a 300-ton salvage tug, built in Denmark in 1898. The ship was seized in World War I and transferred to the command of the marine lines. The first and only naval battle of Türkiye's War of Independence took place in Karadeniz Ereğli; the subsequent successful battle, called the Alemdar Incident, formed the basis of further victories by the Republic of Türkiye. The Alemdar was rebuilt according to its original design, and still serves as a museum.

Yassıkaya Early Bronze Age Settlement

The Yassıkaya Early Bronze Age Settlement (Yassıkaya Erken Tunç Çağı Yerleşimi) is 27 km east of Ereğli, 1 km northwest from the Zoroğlu Settlement of Ramazanlı Village, and 2 km west from the Gözeren Creek. Both sides of the Gözeren Valley are surrounded by rocky cliffs. The backdrop of slopes and plains is covered by forests. The settlement is located on a wide, massive cliff at the southern end of the valley. Yassıkaya is the first prehistoric settlement to have been identified on the coastline that extends from Sinop in the east to the Kocaeli Peninsula in the west.

Çaycuma Kadıoğlu Mosaics

The Ambrosia Mosaic in Kadıoğlu Village was unearthed, and excavations were completed. Believed to have been the floor for a room in the villa, the mosaic is intricately designed, depicting a male figure with a dagger advancing towards a female figure holding a grape cluster. In addition to the mosaic, historical building ruins and embellished pottery fragments were discovered in the same site, although the structure itself was in ruins. Another find was the Roman-era Valerianus Coin, dating from CE 253-260. The ancient coin was minted during the reign of Roman emperor Licinius Valerianus, pointing to the Late Roman Age.

Varagel Tunnel

The Varagel Tunnel (Varagel Tüneli) in the city centre of Zonguldak was built for industrial use. It is by the seaside and inside a rocky area with karstic structural features. Contributing to the natural heritage of the city, the tunnel is nearly 75 years old.

Heraclius Palace and environs

Aside from the ruins standing on both sides, the palace was completely destroyed, the remaining section bears the attributes of an ancient monument, built with large cut-stone blocks and elaborate workmanship. The structure is believed to be a public service building belonging to the Ancient Heracleia Pontike Settlement.

Lighthouse Tower (Çeştepe)

The structure consists of a Lighthouse Tower (Fener Kulesi) built in antiquity, and a Roman-era tumulus beneath it. The tower's current height is 10 metres; it was constructed of cut-stones and bricks. The tumulus was opened in the 1980s; its burial chamber and cut-stone blocks are solid and still standing.

Fener Settlement

Fener Mahallesi is in the city centre of Zonguldak. It was built by the French, who lived in the region about 100 years ago. This section is a protected urban site.

Uzun Mehmet Monument

The Uzun Mehmet Monument (Uzun Mehmet Anıtı) is on the Zonguldak-Kozlu highway. The monument was built to commemorate Uzun Mehmet, who first discovered hard coal in the region. In the area of the monument is a zoo, as well as rest and picnic areas.

Filyos (Tios)

According to legend, the city was founded in the BCE 7th century. Known variously as Tios, Tieion, Tianon, and Tium throughout its history, the city was unable to gain political power in the shadow of Ereğli and Amasra and was burnt and looted in BCE 70 during the Roman period. It was later rebuilt and continued its existence as a trading and fishing town. It became a prominent religious centre in the 5th century during the Byzantine Period, but lost importance during the Seljuk and Ottoman periods (14th-15th centuries) and eventually reverted to a small fishing village.

Filyos Castle

Located in Filyos in the Çaycuma district, Filyos Castle (Filyos Kalesi) is on a promontory overlooking the sea. It is believed to have been built by the Romans. Large stones were used in its construction to give the city a majestic and imposing appearance.

The castle was restored in 2003 after being in ruins for numerous years. The first settlement was located on the castle hill north of the city. Today, the ramparts from the Medieval-era Castle and the ruins of towers dating from the Hellenistic-Roman periods can be seen. Marble columns and pedestals, marble inscription slabs, stone sarcophagi and brick tombs were excavated east of the castle hill.

Bozhane Turkish Bath

Constructed in a classical Turkish bath design of the 19th century, the bath section is made of stone and the changing areas are made of wood. The upper cover system of the wooden sections was reinforced with an old, Turkish-style tile roof. From the changing section at the entrance of the bath, visitors can pass to the warm chamber section, featuring two domes. The restoration of Bozhane Bath (Bozhane Hamamı) is still in progress.
