Which of these has its entrance in Piyer Loti Caddesi, Hagia Sophia or Theodosius Cistern?
Hagia Sophia Hagia Sophia ( ; from the Greek: Αγία Σοφία , ] , "Holy Wisdom"; Latin: "Sancta Sophia" or "Sancta Sapientia"; Turkish: "Ayasofya" ) was a Greek Orthodox Christian patriarchal basilica (church), later an imperial mosque, and is now a museum (Ayasofya Müzesi) in Istanbul, Turkey. The Roman Empire's first Christian Cathedral, from the date of its construction in 537 AD, and until 1453, it served as an Eastern Orthodox cathedral and seat of the Patriarch of Constantinople, except between 1204 and 1261, when it was converted by the Fourth Crusaders to a Roman Catholic cathedral under the Latin Empire. The building was later converted into an Ottoman mosque from 29 May 1453 until 1931. It was then secularized and opened as a museum on 1 February 1935. Famous in particular for its massive dome, it is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture". It remained the world's largest cathedral for nearly a thousand years, until Seville Cathedral was completed in 1520.
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).
