The word originates from the Greek word "stadion" a Greek measure of length roughly 180 - 200m. The oldest known stadium is the one in Olympia, in western Peloponnese, Greece, where the Olympic Games of antiquity were held since 776 BC. Initially 'the Games' consisted of a single event, a sprint along the length of the stadium. Therefore the length of the Olympia stadium was more or less standardized as a measure of distance (approximately 190 meters or 210 yd). The practice of standardizing footrace tracks to a length of 180-200 meters (200-220 yd) was followed by the Romans as well. Greek and Roman stadia have been found in numerous ancient cities, perhaps the most famous being the Stadium of Domitian, in Rome.Dome stadia are distinguished from conventional stadia by their enclosing roofs. They are called stadia because they are large enough for, and designed for, what are generally considered to be outdoor sports. Those designed for what are usually indoor sports are called arenas. Some stadia have partial roofs, and a few have even been designed to have moveable fields as part of the infrastructure.
The term "stadium" tends to be used mostly in connection with games like association football, American football, Baseball, Gaelic football, Cricket, Hurling, Rugby, and other large field games. Exceptions include the basketball arena at Duke University, which is called Cameron Indoor Stadium and the now-demolished Chicago Stadium, former home of the Chicago Blackhawks of the NHL and Chicago Bulls of the NBA.Different sports require fields of different size and shape. Some stadia are designed primarily for a single sport while others can accommodate different events, particularly ones with retractable seating. Stadia built specifically for football are quite common in Europe however Gaelic games Stadia would be most common in Ireland, while ones built specifically for baseball or American Football are common in the United States. The most common multiple use design combines a football pitch with a running track, a combination which generally works fairly well, although certain compromises must be made. The major drawback is that the stands are necessarily set back a good distance from the pitch, especially at the ends of the pitch. The Stadio Delle Alpi in Turin is being remodelled to remove the running track after persistent complaints from fans of Juventus F.C. In the case of some smaller stadia, there are not stands at the ends. When there are stands all the way around, the stadium takes on an oval shape. When one end is open, the stadium has a horseshoe shape. All three configurations (open, oval and horseshoe) are common, especially in the case of American college football stadia. Rectangular stadia are more common in Europe, especially for football where many stadia have four often distinct and very different stands on the four sides of the stadium. These are often all of different sizes and designs and have been erected at different periods in the stadium's history. The vastly differing character of European football stadia has led to the growing hobby of ground hopping where spectators make a journey to visit the stadium for itself rather than for the event held there. In recent years the trend of building completely new oval stadia in Europe has led to traditionalists criticising the designs as bland and lacking in the character of the old stadiua they replace. In North America, where baseball and American football are the two most popular outdoor spectator sports, a number of football/baseball multi-use stadia were built, especially during the 1960s, and some of them were successful.
