Are Cistern of Aetius and Hirami Ahmet Pasha Mosque both churches?
Cistern of Aetius The Cistern of Aetius (), known since the Ottoman period as Çukurbostan ("sunken garden") and since 1928 as Karagümrük stadyumu ("Karagümrük stadium") or Vefa stadyumu ("Vefa stadium"), was a Byzantine open-sky water reservoir in the city of Constantinople, important for historical reasons. Once one of the largest Byzantine cisterns, it is now a football stadium in Istanbul.
Yivliminare Mosque The Alaaddin Mosque or Yivli Minare Mosque (literally: "Fluted Minaret" Mosque), commonly also called Ulu Mosque (Turkish: "Ulu Cami" , "Grand Mosque") in Antalya is a historical mosque built by the Anatolian Seljuk Sultan Alaaddin Keykubad I. It is part of a külliye (complex of structures) which includes the Gıyaseddin Keyhüsrev Medrese, Seljuk and Dervish lodge, and the vaults of Zincirkıran and Nigar Hatun. The mosque is located in Kaleiçi (the old town centre) along Cumhuriyet Caddesi, next to Kalekapısı Meydanı. The mosque's fluted minaret called the Yivli Minare, which is decorated with dark blue tiles, is a landmark and symbol of the city.
