STADIUM

enclosure that combines broad space for athletic games and other exhibitions with large seating capacity for spectators. The name derives from the Greek unit of measurement, the stade, the distance covered in the original Greek footraces (about 600 feet ). The course for the footrace in the ancient Olympic Games at Olympia was exactly a stade in length, and the word for the unit of measurement became transferred first to the footrace and then to the place in which the race was run. As a type of structure, the stadium played a significant role in 20th-century construction technology.
