Church of Saint Mary of the Mongols
Saint Mary of the Mongols (full name in Greek: Θεοτόκος Παναγιώτισσα (pr. "Theotókos Panaghiótissa", lit. "All-Holy Theotokos") or Παναγία Μουχλιώτισσα (pr. "Panaghía Muchliótissa"); Turkish name: "Kanlı Kilise" (meaning: "Bloody Church"), is an Eastern Orthodox church in Istanbul. It is the only remaining Byzantine church of Constantinople that has never been converted to a mosque, always remaining open to the Greek Orthodox Church. Location. The church, which usually is not open to the public and lies behind a high wall, is located in the neighborhood of "Fener", Fatih district. It lies on "Tevkii  Cafer Mektebi Sokak", at the summit of a slope overlooking the Golden Horn, and near to the imposing building of the Phanar Greek Orthodox College. History. 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 1266, the building was enlarged, and a painter, named "Modestos", decorated it. In 1281, Maria Palaiologina, illegitimate daughter of Emperor Michael VIII and widow of Abaqa, Khan of the Mongolian Il-Khanate, 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. The nunnery existed until the end of the Empire, then was abandoned. On May 29, 1453, the day of the Fall of Constantinople, the surroundings of the building saw the last desperate resistance of the Greeks against the invading Ottomans. Due to that, the church got the Turkish name "Kanlı Kilise" ("Church of the Blood"), and the road that leads  to it from the Golden Horn is still named the "Ascent of the Standard Bearer" (Turkish: "Sancaktar yokuşu"), in honour of an Ottoman standard bearer who found his death fighting here. 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 forgotten. 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. The complex lies behind a high wall, and it is usually not open to the public. Although it has always remained in Greek hands, the building has been modified much more heavily than those converted into mosques. It has, or originally had, a tetraconch plan with a central dome enclosed by a tower, which renders it a unicum in the Byzantine architecture of Constantinople and, on a much  smaller scale surprisingly anticipates those of many great Ottoman mosques. The dome rests on a cross formed by four half-domes. The narthex has three bays, whose central bay is covered by a barrel vault. On the south side, the church has been demolished and rebuilt, and the southern half dome and the southern bay of the narthex have been removed and replaced by three aisles. The interior has been stripped of the original decoration, but it is filled with icons and other ornaments, making an examination of the church very difficult. On the eastern wall there is a large  representation of the Last Judgement, perhaps painted by Modestos in 1266. Moreover, noteworthy are a mosaic Icon from the eleventh century portraying the Theotokos, and four Icons dating from the thirteenth and fourteenth century. Under the church are visible excavations, and an underground passage said to reach Hagia Sophia (although the two buildings are several kilometers apart). Despite its historical importance, the church has never been studied from an architectural point of view. Sources.
