The hippodrome (Greek: ??????????) was an ancient Grecian stadium for horse racing and chariot racing. The name is derived from the Greek words hippos (?????; "horse") and dromos (??????; "course"). The term is used in the modern French language and some others, with the meaning of "horse racecourse". Hence, some present-day horse racing tracks also include the word hippodrome in their names, such as the Hippodrome de Vincennes and the Central Moscow Hippodrome.
The Greek hippodrome was similar to the Roman Circus. The hippodrome was not a Roman amphitheatre which was used for spectator sports, games and displays, or a Greek or Roman semi-circular theater used for theatrical performances.
The Greek hippodrome was usually set out on the slope of a hill, and the ground taken from one side served to form the embankment on the other side. One end of the hippodrome was semicircular, and the other end square with an extensive portico, in front of which, at a lower level, were the stalls for the horses and chariots. At both ends of the hippodrome there were posts (termai) that the chariots turned around. This was the most dangerous part of the track, and the Greeks put an altar to Taraxippus (disturber of horses) there to show the spot where many chariots wrecked.
