    In depth

    Behind the great mosques of the old city, smaller Byzantine churches still stand in the side streets. A private Byzantine churches tour takes you to four of them, with your own guide and driver.

    Kalenderhane on the Byzantine Churches Tour

    First, your driver takes you to the Valens Aqueduct, where Kalenderhane stands by its arches. Frescoes found inside name the Virgin as Kyriotissa, and a Gothic inscription recalls Saint Francis of Assisi from the time of Latin rule. After the conquest, Mehmed II gave it to the Kalenderi dervishes. Today, it is a working mosque, so you visit it if open, outside prayer times.

    The Fenari İsa Mosque

    Next, you drive to Vatan Street and the Fenari İsa Mosque. Here, the admiral Constantine Lips founded a convent in the early 10th century. Empress Theodora added a second church beside the first, and the Palaiologos family chose it for their tombs. In the late 15th century, it became a mosque, and you visit it if open.

    The Pammakaristos on the Byzantine Churches Tour

    After lunch, paid on the spot, you climb to Çarşamba and the Pammakaristos. After the conquest, the Orthodox patriarchs moved here, and they stayed for about a century and a half. Later, Murad III made it the Fethiye Mosque. Its museum chapel stays closed at present, so you see the church from outside.

    Saint Mary of the Mongols

    Finally, you walk down to Fener and Saint Mary of the Mongols, near the Red School. Maria Palaiologina, a daughter of Michael VIII and the wife of the Mongol ruler Abaqa, restored its convent in the 13th century. After the conquest, a decree of Mehmed II protected it, and it is the only Byzantine church in the city still in use as a church. So you see it from the gate, or inside if open.
