The Kefeli Mosque (Turkish: Kefeli Câmîi, meaning "the mosque of the Caffariotes", after the inhabitants of the city of Caffa in Crimea, or also Kefeli Mescidi, where Mescit is the Turkish word for a small mosque) is a former Eastern Orthodox church, later jointly officiated by Roman Catholics and Armenians, and finally converted into a mosque by the Ottomans. The Catholic Church was dedicated to Saint Nicholas. Its date of dedication as an Eastern Orthodox church is unknown, but it is commonly identified with the 9th-century Monastery of Manuel (Greek: Μονὴ τοῦ Μανουήλ). The interest of Kefeli Mosque arises because it repurposes the early Christian basilica form during the later Byzantine period.

The Odalar Mosque (Turkish: Odalar Câmîi, meaning "the mosque of the barracks" after the nearby accommodations of the married Jannisaries established in this quarter in the 18th century. Also: Kemankeş Mustafa Paşa Câmîi) was an Ottoman mosque in Istanbul. The building was originally a Byzantine-era Eastern Orthodox church of unknown dedication. In 1475, after the Fall of Constantinople (1453), it became a Roman Catholic church, dedicated to Saint Mary of Constantinople, until finally it was converted into a mosque by the Ottomans in 1640. The mosque was destroyed by fire in 1919, and since then has fallen into ruin. As of 2011, only some walls remain, hidden among modern buildings.

Kasım Ağa Mosque (Turkish: Kasım Ağa Mescidi; also Kâsım Bey Mescidi, where mescit is the Turkish word for a small mosque) is a former Byzantine building converted into a mosque by the Ottomans in Istanbul, Turkey. Neither surveying during the last restoration nor medieval sources have made it possible to find a satisfactory answer as to its origin and possible dedication. It is probable that the small building was part of the Byzantine complex and monastery whose main church was the building known in Ottoman era as the Odalar Mosque, whose dedication is also uncertain. The edifice is a minor example of Byzantine architecture in Constantinople.

Hirami Ahmet Pasha Mosque (Turkish: Hırami Ahmet Paşa Mescidi) is a former Eastern Orthodox church converted into a mosque by the Ottomans. The small church, one among the 36 dedicated to Saint John the Baptist in Constantinople, was part of a monastery bearing the same name. Its full name was Saint John the Forerunner by-the-Dome (Greek: Ἃγιος Ἰωάννης ὁ Πρόδρομος ἐν τῷ Τρούλλῳ, Hagios Ioannis ho Prodromos en tō Trullō). It is the smallest Byzantine church of Constantinople still extant and has never been studied.

Çarşamba is a small part of the Fatih district of Istanbul, Turkey, close to the Fatih Mosque. It is one of the most conservative areas of the city. According to the 17th-century Ottoman traveler Evliya Çelebi, the district takes its name from the town of Çarşamba on the Black Sea coast since, after the Fall of Constantinople in 1453, this part of the city was repopulated with people from Çarşamba. However, others think it acquired its name from the large Wednesday (Çarşamba in Turkish) Market held here every week. The neighbourhood is home to two Byzantine churches that were converted into mosques after the Conquest of Constantinople in 1453: the Fethiye and Hirami Ahmet Pasha mosques. Çarşamba is also home to the Sultan Selim Mosque, built by Sultan Suleiman the Magnificent for his father Yavuz Sultan Selim (Selim the Grim in English) whose shrine stands in the grounds. The mosque is usually attributed to Mimar Sinan although there is no record of it in the official list of his works. it was a favourite with the Swiss-French architect Le Corbusier who admired its simplicity of form. Here, too, is the İsmail Ağa Mosque, built in 1724, and named after a Şeyhülislam named İsmail Efendi (1645-1725). Its congregation has a particular reputation for conservatism.

The Pammakaristos Church, also known as the Church of Theotokos Pammakaristos (Greek: Θεοτόκος ἡ Παμμακάριστος, "All-Blessed Mother of God"), is one of the most famous Byzantine churches in Istanbul, Turkey, and was the last pre-Ottoman building to house the Ecumenical Patriarchate.. Converted in 1591 into the Fethiye Mosque (Turkish: Fethiye Camii, "mosque of the conquest"), it is today partly a museum housed in a side chapel or parekklesion. One of the most important examples of Constantinople's Palaiologan architecture, the church contains the largest quantity of Byzantine mosaics in Istanbul after the Hagia Sophia and Chora Church. The church-mosque is in the Çarşamba neighbourhood of the Fatih district inside the walled city of Istanbul.
