For travelers fascinated by Byzantine history and those eager to discover hidden cultural landmarks, the Church of Saint Mary of the Mongols in Istanbul’s Fener district is a remarkable site worth exploring. This centuries-old church stands out as the only Byzantine church in Istanbul that was never converted into a mosque, preserving its original function from the late 13th century to the present day.
Walking through the narrow, historic streets of Fener, this unassuming yet historically rich church is a true hidden gem for those looking to step off the beaten path and immerse themselves in the city’s layered past.
The Church of Saint Mary of the Mongols (Meryem Ana Rum Ortodoks Kilisesi) has an extraordinary backstory tied to imperial politics, Mongol alliances, and Byzantine resilience.
The church was founded in the late 13th century by Maria Palaiologina, daughter of Byzantine Emperor Michael VIII Palaiologos. Maria was married to Abaqa Khan, the ruler of the Mongol Ilkhanate, as part of a political alliance between the Byzantines and the Mongols. However, after Abaqa Khan’s death, Maria returned to Constantinople (now Istanbul) and decided to dedicate herself to religion and charity.
She established a monastery and church complex, originally known as Theotokos Panagiotissa, which later became popularly referred to as the Church of Saint Mary of the Mongols due to her connections to the Mongol Empire.
Unlike many Byzantine churches in Istanbul, which were converted into mosques following the Ottoman conquest in 1453, the Church of Saint Mary of the Mongols remained a Christian place of worship.
This is largely thanks to a special decree by Mehmed the Conqueror, granting the Greek Orthodox community the right to continue using the church. This rare and exceptional status makes the Church of Saint Mary of the Mongols the only Byzantine church in Istanbul that has continuously served as a church since its foundation.
While not as grand as some of Istanbul’s other Byzantine churches, the Church of Saint Mary of the Mongols holds great historical and artistic value.
While the church is not always open to visitors, those who enter will experience a rare, preserved piece of Byzantine spirituality in modern Istanbul.
