The Ancient Hippodrome from the Roman period had many monuments in its central axis. One of these monuments was the Serpentine Column which was brought from Delphi in Greece. It is made with bronze with three intertwined serpents.
The Hippodrome was destroyed and plundered in 1204 by the Crusaders.
During the Turkish period it lost its popularity, especially with the construction of the Blue Mosque. The ancient Hippodrome changed its name and became Atmeydanı (Horse Square), a place where Ottomans trained their horses.
