Date: 14/06/2025

Introduction

The Church of St. Mary of the Mongols is an extraordinary monument in Istanbul’s Fener district, distinguished as the city’s only Byzantine church never converted into a mosque. This rare status has preserved its integral role in the Greek Orthodox community and established it as a living testament to the city’s vibrant, multi-layered religious and architectural history. Founded in the 7th century and reconstructed in the late 13th century by Maria Palaiologina, daughter of Emperor Michael VIII Palaiologos, the church encapsulates a fascinating narrative of diplomacy, faith, and cultural exchange between Byzantium and the Mongol Ilkhanate (The Byzantine Legacy; Wikipedia).

Origins and Foundation

The Church of St. Mary of the Mongols, also known as Kanlı Kilise (“Bloody Church”) in Turkish and Panagia Mouchliotissa in Greek, traces its origins to a 7th-century nunnery established by Princess Sopatra and her companion Eustolia (thebest.istanbul). The current church owes its form to Maria Palaiologina, who after her marriage to Mongol ruler Abaqa Khan and subsequent return to Constantinople in the late 13th century, rebuilt the site using her personal fortune. She became the ktētorissa (“foundress”) of the church and monastery, supporting a community of 33 nuns and endowing it with properties and resources (Wikipedia; The Byzantine Legacy; arha318.files.wordpress.com). The name “of the Mongols” reflects Maria’s distinguished connection to the Mongol Ilkhanate, highlighting Constantinople’s cosmopolitan character during the late Byzantine era (triphobo.com).

Architectural Evolution

This church is notable for its Byzantine cross-in-square plan, red brickwork, and central dome supported by pendentives—a design both beautiful and robust in the face of Istanbul’s frequent earthquakes (Istanbul.tips). The original structure was likely a tetraconch plan, with later additions including a narthex and decorative enhancements by Maria Palaiologina. Fires in the 17th and 18th centuries prompted significant repairs and expansions, including the addition of a bell tower in the 19th century and the construction of an adjacent girls’ school (arha318.files.wordpress.com). Despite these changes, the church retains core Byzantine features and exhibits both Byzantine and Mongolian influences—a testament to its unique patronage.

Cultural and Religious Significance

St. Mary of the Mongols stands as the only Byzantine church in Istanbul that has never been converted into a mosque, thanks to a firman (imperial decree) from Sultan Mehmed II—a document still displayed inside the church (Wikipedia). This protection, reaffirmed by later sultans, signifies the church’s exceptional status and its role as a symbol of religious coexistence during the Ottoman period (turkiyeworld.com). The Turkish moniker “Kanlı Kilise” (Bloody Church) refers to fierce fighting in the church’s vicinity during the fall of Constantinople in 1453, further embedding it in the city’s collective memory.

The church has continuously served as a hub for the Greek Orthodox community, providing a living connection to the city’s Byzantine Christian heritage and resilience in the face of political and social upheaval.

Notable Events and Legal Struggles

After Maria Palaiologina’s death, her heirs attempted to appropriate the convent’s properties, leading to legal disputes resolved in favor of the nuns by Emperor Andronikos III and the Patriarchate (arha318.files.wordpress.com). Throughout the Ottoman era, the church narrowly escaped conversion into a mosque multiple times, with its protected status preserved by influential community members and state decrees (Wikipedia). Damage from fires and acts of vandalism—most notably during the anti-Greek Istanbul Pogrom of 1955—has been met with ongoing restoration and conservation efforts (The Byzantine Legacy).
