MMA fights are held all over the world. In the U.S., most UFC fights take place on the West and East Coasts of the U.S. in areas such as Las Vegas, California, New Jersey and Connecticut. But Canada is the current Mecca of the sport, with Brazil close behind. The unique aspect of MMA arenas is that the fighting area is an eight-sided cage called “The Octagon.” The walls of the Octagon range from 5ft 6in to 5ft 8in in height, and are made up of metal chain-link fences with foam padding at the top and on the sides. Fighters enter the cage from one of two gates that are positioned directly opposite each other.
