Orhangazi Mosque, built as a church in Karadeniz Ereğli between 408-450 AD, is the first of Turkey's nine Hagia Sophias, a historical structure with a wooden ceiling and a single minaret, used as a mosque since the 1300s.
Orhangazi Mosque stands in Orhanlar Neighborhood, Karadeniz Ereğli. The structure was originally built as a church named Hagia Sophia between 408-450 AD during the reign of Theodosius II. It is reported to be one of the nine Hagia Sophia churches within Turkey's borders, and even the first one built. In the 1300s, it was converted into a mosque after Orhan Gazi's conquest and named after the sultan. Due to its location in the neighborhood, it is also known as Orta Cami (Middle Mosque) among the locals.
Today, it serves as a small-scale mosque with a wooden ceiling and a single minaret. Some visitors say that the old texture inside is partially preserved, and some wall and calligraphy writings are noteworthy. However, not everyone shares the same satisfaction. Some comments complain about the mosque's exterior being covered with plaster and the adjacent apartments on the roof spoiling the historical appearance. Since it is not always possible to enter, some visitors have returned without being able to see the details of the structure up close.
Its walking distance to Ereğli Port and the bus station makes it an easy stop to add to a short city tour. Since there is no street parking, it is more practical to go on foot.

Guide's Note
History: From Church to Mosque
The origin of the structure dates back to 408-450 AD, during the reign of Roman Emperor Theodosius II. At that time, it was built as a church named Hagia Sophia (Holy Wisdom). It is highlighted in sources that it is one of the nine Hagia Sophia churches located within Turkey's borders, and even the first one built. After the region was conquered by Orhan Gazi in the 1300s, the structure was converted into a mosque and began to be known by the sultan's name. It has been serving as a mosque for over 700 years.
How to Get There?
The mosque is located within the borders of Orhanlar Neighborhood in the city center of Karadeniz Ereğli. Since it is a 5-minute walk from Ereğli Port and a 10-minute walk from the bus station, it can be visited by those spending time in the city center without additional time loss. It is recommended to go on foot as it is difficult to find parking on the street.
Architecture and Appearance
The mosque has a flat tiled roof, a single balcony (şerefe), and a single minaret. Its interior has a predominantly wooden texture; it is a simple and small-scale structure. One visitor noted that the calligraphy on the walls resembled a mosque in Edirne. However, some also say that the historical texture is not fully preserved due to the plastered exterior and the apartments adjacent to the roof.
Things to Know Before Visiting
The interior may not always be open to visitors; some visitors have returned without seeing the inside because they found it closed. Also, some mention that there are no coverings for visitors, so it would be useful for female visitors to bring a headscarf. There is no street parking, so you may need to park your car a little further away and walk.
What to See in Ereğli?
The mosque is close to Ereğli Port, making it a stop that can be combined with the coastal area. A short walk in the city center also leads to the bus station, port, and bazaar area. Since there are multiple mosques named Orhangazi in Zonguldak, make sure this structure in the center is the correct address: Orhanlar Mahallesi.
Visit Duration
Since the mosque is small-scale, a visit usually takes 15-30 minutes. If combined with other stops in Ereğli (port, coast, bazaar), it can be turned into a half-day city tour.
