 Bullrings evolved as specialized sporting arenas hand-in-hand with the sport that demanded them.Many of the ancient Roman amphitheatres had characteristics that can be seen in the bullrings of today (in fact the ring in Nîmes, France, is a Roman artifact, though it is more elliptical than the usual plaza), and the origin of bullfighting is very closely related to certain Roman traditions; in the formative years of the sport on the Iberian Peninsula, those Roman enclosures were not commonly utilised for bullfighting events.Back when bullfighting festivals were conducted principally on horseback, the spectacle was a more public affair that took place in the city's open plaza area.
