Goodwill Cistern
Şerefiye Cistern or Theodosius Cistern (Greek: Κινστέρνα Θεοδοσίου Kisterna Theodosiou) is one of the many Byzantine Period cisterns in the Historical Peninsula in the Fatih district of Istanbul. It is located in the south of the building island bounded by Divan Yolu Street, Piyer Loti Street, Boyacı Ahmet Street and Dostluk Yurdu Street. Considering the historical topography of Constantinople during the Byzantine Period, the building is located south of the ancient Mese road, southeast of the Forum of Constantine and west of the Binbirdirek Cistern. It is among the cisterns that could benefit from the transmission line on the Mese.
The structure was first documented by Forscheimer and Strzygowski in 1893.
