Manastır Mosque

Manastır Mosque (Manastır Mescidi, also Mustafa Çavuş Mescidi, where mescit is the Turkish word for a small mosque) is a former Eastern Orthodox church converted into a mosque by the Ottomans. Neither archeological excavations nor medieval sources have made it possible to find a satisfactory answer as to its original dedication as a church. It is however possible that the small building was part of the Byzantine monastery dedicated to the Holy Martyrs Menodora, Metrodora, and Nymphodora (ῆ ῶ, ὶ), or an annex of the nunnery of Kyra Martha (ῆ ἠ). The edifice is a minor example of Byzantine architecture in Constantinople, and is important for historical reasons.
