Were Anadoluhisarı and Gül Mosque in Istanbul both constructed by the Ottomans?
Gül Mosque Gül Mosque (Turkish: "Gül Camii" , meaning: "The Mosque of the Rose" in English) is a former Eastern Orthodox church in Istanbul, Turkey, converted into a mosque by the Ottomans.
Sancaktar Hayrettin Mosque Sancaktar Hayrettin Mosque (Turkish: "Sancaktar Hayrettin Câmîi" ; also "Sancaktar Hayrettin Mescidi", where "Mescit" is the Turkish word for a small mosque, or "Sancaktar Mescidi") is part of a former Eastern Orthodox monastery converted into a mosque by the Ottomans. It is generally believed that the small building belonged to the Byzantine Monastery of Gastria (Greek: , "Monē tōn Gastríōn", meaning "Monastery of the Vases"). The edifice is a minor example of Palaiologan architecture in Constantinople, and is important for historical reasons.
