Fodor's Expert Review Şerefiye Sarnıcı

The major problem with the site of Byzantium was the lack of fresh water. So, for the city to grow, a great system of aqueducts and cisterns was built. Impeccably restored and opened to the public in 2018, the Theodosius Cistern dates from the 5th century to the reign of Theodosius II. A steep staircase leads you down into the cistern, where 32 marble columns support the Byzantine arches and domes overhead. The cistern occasionally hosts concerts and art exhibitions.
