Hagia Sophia Cathedral in Trabzon is located west of the center of Trabzon, not far from the Black Sea coast. It is one of the most notable monuments of the Byzantine period in the city, connected with the history of the Empire of Trebizond. The church was built in the 13th century and has preserved features of late Byzantine architecture, which make it easy to distinguish from later Ottoman structures.

The building is known for its well-planned composition, stone carving, and remains of wall paintings. Particularly interesting are the relief details of the facades, the arches, and the design of the entrances, while inside there are preserved frescoes considered among the valuable examples of medieval church art on Turkey's Black Sea coast. Even taking later reconstructions into account, the cathedral conveys the characteristics of the era in which it was created remarkably well.

The history of the monument reflects the succession of cultural and political periods in Trabzon. After the Ottoman conquest, the church was used as a mosque, in the 20th century it served for some time as a museum, and later it became a mosque again. For visitors, it is not only a religious site but also an important place where Byzantine heritage and later changes can be seen combined in a single building.

The cathedral will be of interest to those who want to better understand the history of Trabzon beyond the usual walk along the waterfront and central streets. People come here for the architecture, the historic atmosphere, and the rare fragments of medieval painting that have survived despite the building's long and complex history.
