hippodrome

n. stadium where chariot races or horse races were held (in ancient Greece and Rome); arena in which various events are held

A Hippodrome (Gr. from hippos, horse, and dromos, race, course) was a course provided by the Greeks for horse racing and chariot racing. Some present-day horse racing tracks are also called hippodromes, for example the Central Moscow Hippodrome.It corresponded to the Roman Circus Maximus, except that in the latter only four chariots ran at a time, whereas ten or more contended in the Greek games, so that the width was far greater, being about 400 ft., the course being 600 to 700 ft. long. It should not be confused with the Roman amphitheatre which was used for spectator sports, games and displays, or the Greek and Roman theatres which were semi-circular and used for theatrical performances.
