Church of St. Mary of Blachernae (Istanbul)

Ayvansaray is a neighborhood in Istanbul, Turkey. It is part of the district of Fatih and part of the walled city. It lies between the southern shore of the Golden Horn, the Blachernae section of the Walls, and the neighborhoods of Balat and Edirnekapı. It corresponds to the old quarter of Blachernae (Vlachérnai in Greek). The name Ayvansaray is from Persian ایوان‌سرای (Iwan + Saray) and means "Veranda Palace". This name hearkens back to the Palace of Alexios I Komnenos (now disappeared), which was part of the complex of Blachernae.Ayvansaray has a number of historic monuments, like the Palace of the Porphyrogenitus (Tekfur Palace), the mosque of Atik Mustafa Pasha (originally a medieval Byzantine church), and the Ayazma ("holy spring") enclosed in the small church of St. Mary of Blachernae. It is a picturesque quarter.

Toklu Dede Mosque (Turkish: Toklu Dede Mescidi, where mescit is the Turkish word for a small mosque), was an Ottoman mosque in Istanbul, Turkey. The building was originally a Byzantine Eastern Orthodox church of unknown dedication. It was almost completely destroyed in 1929.

Atik Mustafa Pasha Mosque (Turkish: Atik Mustafa Paşa Camii; also named Hazreti Cabir Camii) is a former Eastern Orthodox church in Istanbul, converted into a mosque by the Ottomans. The dedication of the church is obscure. For a long time it has been identified with the church of Saints Peter and Mark, but without any proof. Now it seems more probable that the church is to be identified with Saint Thekla of the Palace of Blachernae (Greek: Άγία Θέκλα τοῦ Παλατίου τῶν Βλαχερνών, Hagia Thekla tou Palatiou tōn Vlakhernōn). The building belongs stylistically to the eleventh-twelfth century.

The Prison of Anemas (Turkish: Anemas Zindanları) is a large Byzantine building attached to the walls of the city of Constantinople (modern-day Istanbul, Turkey). It is traditionally identified with the prisons named after Michael Anemas, a Byzantine general who rose in unsuccessful revolt against Emperor Alexios I Komnenos (r. 1081–1118) and was the first person to be imprisoned there. The prison features prominently in the last centuries of the Byzantine Empire, when four Byzantine emperors were imprisoned there.

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).

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 Defterdar Mosque, or the Defterdar Mahmut Efendi Mosque (Turkish: Defterdar Camii, Defterdar Mahmut Efendi Camii), is 16th century Ottoman mosque located in Eyüp, Istanbul, Turkey. It was commissioned by Defterdar Nazlı Mahmut Efendi (c. 1500–1546) and built by architect Mimar Sinan in 1542 ("defterdar" was the head of the financial department in Ottoman Empire). Instead of a crescent, this mosque has "ink pot and pen" on top of its dome, representing the profession of the founder of the mosque. (since "defterdar" means chamberlain, literally it means defter:notebook + dar:suffix for "doer"). The original pair was broken by a storm in 1997. Ten years later, on 30 May 2007, a new inkpot and a pen assembled on top of the dome of the mosque.
