The Hippodrome, also known and the Sultanahamet Square, is a square which was previously a circus that was the sporting and social center of Constantinople, capital of the Byzantine Empire. Nowadays there's nothing to indicate its past glory, except for the Serpent Column, erected to celebrate the Greeks' victory over the Persians in the 5th century BC and moved from the Temple of Apollo at Delphi to the middle of the Hippodrome at the order of Emperor Constantine. At the top of the column there was a golden bowl supported by three serpent heads. The serpent heads were destroyed in the 1700. The other monument here is an Egyptian obelisk built during the reign of Thutmose III and brought to adorn the Hippodrome at the order of Theodosius the Great, in 390.
