Fener Greek Male High School

Fener Greek Male High School, (currently known as the Private Fener Greek Middle School and High School) is the oldest continuously operating Greek-Orthodox educational institution in Istanbul, located in the Fener neighborhood of theFatihdistrict. Founded in 1454, it is also known by its Greek name Μεγάλη του Γένους Σχολή (Great School of the Nation) and has served as a major center of education and culture throughout Ottoman and modern Turkish history.

Fener Greek Male High School was established in 1454, shortly after the conquest of Istanbul, through the initiative of Patriarch Gennadios Scholarios. Its first headmaster was Matthaios Kamariotis, a scholar from Thessaloniki. The school functioned as the continuation of the Patriarchal Academy of the Byzantine era and provided education to the children of leading families within the Greek-Orthodox community during the Ottoman period. Among its alumni are Ottoman grand viziers, princes of Wallachia and Moldavia, and other prominent figures.

Throughout its history, the school has been known by various names: "Patriarchal Academy", "Rum Mekteb-i Kebiri", "Red School", and "First Academy". During the Republican era, it adopted the name "Fener Greek Male High School".

The current school building was constructed between 1881 and 1883 by the Greek architect Konstantinos Dimadis. Built with red bricks imported from Marseille, France, the structure is popularly known as the "Red School" or "Red Castle". Its construction was made possible through the financial support of the Greek banker Georgios Zariphis.

The building stands out for its eclectic architectural style and boasts a grand appearance reminiscent of European castles. The large dome at the top was used as an observatory for astronomy lessons and contains an ancient telescope.

Today, Fener Greek Male High School operates under the name Private Fener Greek Middle School and High School and provides mixed-gender education. In 1989, it began admitting students from the adjacent Yuvakimion Girls High School, transitioning to coeducation. In addition to the curriculum set by the Ministry of National Education of the Republic of Türkiye, the school offers instruction in the Greek language, literature, and religion. The teaching staff consists of both Turkish and Greek educators.

Fener Greek Male High School is one of Istanbul's cultural heritage landmarks due to its architecture and history. Since 2024, it has been open to visitors only on specific days of the year by special permission. The building, visible from both banks of the Golden Horn, is one of the iconic structures contributing to Istanbul's skyline.
