At the beginning of the 7th century, Princess Sopatra (daughter of the
Byzantine Emperor Maurikios), and her friend Eustolia built a
nunnery on the slope of the fifth hill of Constantinople. The ground, which was bestowed by the Emperor, lay north of the
Cistern of Aspar and had been used up to then as a cemetery. The building was dedicated to Saint Eustolia. During the 11th century, a
monastery was added. It was dedicated to
All Saints, and had a close relationship with the monastery of the
Great Lavra, on
mount Athos. During the
Latin domination after the
Fourth Crusade, the monastery disappeared. In 1261, after the reconquest of the city by the Byzantines, Isaac
Doukas, father-in-law of
George Acropolites and maternal uncle of
Michael VIII Palaiologos, rebuilt a simple, one-storey monastery, dedicated to the
Theotokos Panaghiotissa. In 1281,
Maria Palaiologina, illegitimate daughter of Emperor
Michael VIII and widow of
Abaqa,
Khan of the
Mongolian
Ilkhanate, returned to Constantinople after an absence of 15 years. She is said to have rebuilt the nunnery and the church (which then assumed the shape still seen today), deserving the title of
Ktētorissa ("foundress") of that complex, and retired there until her death. Since that time, the nunnery and the church got the appellation of
Mouchliōtissa ("of the Mongols" in Greek). After her death the convent decayed, because her heirs used the properties of the nunnery for their purposes, and had even raised a mortgage on them. Finally the nuns started a suit with the heirs first before the Emperor, and then before the Patriarch. The heirs presented as proof of their right an imperial
chrysobull certifying the purchase of the nunnery from Maria Palaiologina, but the document was deemed false, so that the
Patriarchate restored the rights of the nuns. s of Mehmed II and Bayazid II, which granted ownership of the church to the Greek community Tradition holds that Sultan
Mehmed II endowed the church to the mother of
Christodoulos, the Greek architect of the mosque of
Fatih, in acknowledgment of his work. The grant was confirmed by
Bayazid II, in recognition of the services of the nephew of Christodoulos, who built
the mosque bearing that sultan's name. Under Sultans
Selim I and
Ahmed II there were two Ottoman attempts to convert the church into a
mosque (the last one, pursued by
Grand Vizier Ali
Koprülü at the end of the seventeenth century, was thwarted by
Dimitrie Cantemir) but, thanks to the grants of Mehmed II and Bayazid II, the church remained a
parish of the Greek community. Thus, Saint Mary of the Mongols is one among the few Byzantine churches of Istanbul whose ancient
dedication was never changed. Damaged several times (in 1633, 1640 and 1729) by fires that ravaged Fener, the building was repaired and enlarged, losing altogether its primitive elegance. At the end of nineteenth century a small school was built close to it, and in 1892 a small bell tower was added. In 1955, the church was damaged during the anti-Greek
Istanbul Pogrom, but since then it has been restored. ==Description==
