Which of these has its entrance in Piyer Loti Caddesi, Hagia Sophia or Theodosius Cistern?
Theodosius Cistern The Theodosius Cistern (Greek: Κινστέρνα Θεοδοσίου , Turkish: Şerefiye Sarnıcı ) is one of many ancient cisterns of Constantinople that lie beneath the city of Istanbul, Turkey. The modern entrance is in Piyer Loti Caddesi, Fatih.
Serpent Column The Serpent Column (Ancient Greek: Τρικάρηνος Ὄφις "Τrikarenos Οphis" "Three-headed Serpent"; Turkish: "Yılanlı Sütun" "Serpentine Column"), also known as the Serpentine Column, Plataean Tripod or Delphi Tripod, is an ancient bronze column at the Hippodrome of Constantinople (known as "Atmeydanı" "Horse Square" in the Ottoman period) in what is now Istanbul, Turkey. It is part of an ancient Greek sacrificial tripod, originally in Delphi and relocated to Constantinople by Constantine the Great in 324. It was built to commemorate the Greeks who fought and defeated the Persian Empire at the Battle of Plataea (479 BC). The serpent heads of the 8 m high column remained intact until the end of the 17th century (one is on display at the nearby Istanbul Archaeology Museums).
