Edirnekapı, Fatih

The Kariye Mosque (Turkish: Kariye Camii), and formerly known as the Church of the Holy Saviour in Chora (Greek: Ἐκκλησία τοῦ Ἁγίου Σωτῆρος ἐν τῇ Χώρᾳ), was a medieval Greek Orthodox church, now used as a mosque, in the Edirnekapı neighborhood of Istanbul, Turkey. The neighborhood is situated in the western part of the municipality (belediye) of the Fatih district. The building is an example of Byzantine architecture. In the 16th century, during the Ottoman era, it was converted into a mosque; it became a museum in 1945, and was turned back into a mosque in 2020 by President Recep Tayyip Erdoğan. Its desecularization has, however, been halted as of January 2021 due to lack of Islamic cultural significance and clerical interest in the site, compared to the Hagia Sophia. The interior of the building is covered with some of the oldest and finest surviving Byzantine Christian mosaics and frescoes; they were uncovered and restored after the building was secularized and turned into a museum.

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.

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.

Blachernae (Medieval Greek: Βλαχέρναι) was a suburb in the northwestern section of Constantinople, the capital city of the Byzantine Empire. It is the site of a water source and a number of prominent churches were built there, most notably the great Church of St. Mary of Blachernae (Panagia Blacherniotissa), built by Empress Pulcheria in c. 450, expanded by Emperor Leo I (r. 457–474) and renovated by Emperor Justinian I (r. 527–565) in the 6th century.

The Palace of the Porphyrogenitus (Greek: τὸ Παλάτιον τοῦ Πορφυρογεννήτου), known in Turkish as the Tekfur Sarayı ("Palace of the Sovereign"), is a late 13th-century Byzantine palace in the north-western part of the old city of Constantinople (present-day Istanbul, Turkey). An annex of the greater palace complex of Blachernae, it is the best preserved of the three Byzantine palaces to survive in the city (together with the ruins of the Boukoleon Palace; and the ruins of the Great Palace of Constantinople with its surviving substructures, retrieved mosaics and standing Magnaura section), and one of the few relatively intact examples of late Byzantine secular architecture in the world.

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 Palace of Blachernae (Greek: τὸ ἐν Βλαχέρναις Παλάτιον) was an imperial Byzantine residence in the suburb of Blachernae, located in the northwestern section of Constantinople (today located in the quarter of Ayvansaray in Fatih, Istanbul, Turkey). The area of the palace is now mostly overbuilt, and only literary sources are available as to its description.

Boğdan Sarayi (Turkish for "Palace of Bogdania (Moldavia)") was an Eastern Orthodox church in Turkey's largest city, Istanbul. Erected in the Byzantine era, its original dedication is unknown. In the Ottoman era the small edifice, being dedicated to St. Nicholas of Myra, was known as Agios Nikólaos tou Bogdansarághi (Greek: Ἅγιος Νικόλαος τοῦ Βογδανσαράγι). and was part of the Istanbul residence of the Moldavian hospodar′s legation to the Ottoman Porte. The building – whose parts above ground have almost completely disappeared – is a minor example of Byzantine architecture in Constantinople.

The Cistern of Aetius (Greek: ἡ Κινστέρνη τοῦ Ἄετίου) was an important Byzantine water reservoir in the city of Constantinople. Once one of the largest Byzantine cisterns, it is now a football stadium in Istanbul. Since 1928 it has been known as Karagümrük stadyumu, 'Karagümrük stadium' or Vefa stadyumu, 'Vefa stadium', while in the Ottoman period it was known as the Turkish: Çukurbostan, lit. 'sunken garden'.

Vefa Stadı (English: Vefa Stadium) (also named Karagümrük Stadı/Arena) is a football stadium located in Fatih, Istanbul that is the home ground of Fatih Karagümrük.Vefa Stadı is occasionally in use for the promotional play-off encounters in lower tier leagues, other sports including American Football and for public holiday ceremonies.

Ahrida (Ohrid) Synagogue (Hebrew: קהל קדוש אכרידה) is one of the oldest synagogues in Istanbul, Turkey. It is located in Balat, once a thriving Jewish quarter in the city.

Vasat Atik Ali Pasha Mosque (Turkish: Vasat Atik Ali Paşa Camii), also known as Zincirlikuyu Mosque (Turkish: Zincirlikuyu Camii) or Karagümrük Mosque, is an Ottoman mosque located in the Karagümrük neighbourhood of the Fatih district in Istanbul, Turkey, on Fevzipaşa Street. Sultan Bayezid II's grand vizier Hadım Atik Ali Pasha, after whom the mosque is named, ordered its construction in 1502, and it was completed in 1512, one year after the grand vizier's death. The mosque is one of only two mosques in Istanbul with multiple domes, the other being Piyale Pasha Mosque, both having six domes. The mosque was known as Zincirlikuyu Mosque for a long time because of its location next to a well known as Zincirlikuyu (zincirli "chained", kuyu "well"). The minaret of the mosque collapsed in June 1648 after an earthquake. In 2013, repairs began on the minaret at a cost of 2.2 million TL ($1.03 million), expected to be completed in 2014. Pictures in the gallery below that were taken in 2015 show the restoration is finished.
