The Bending Arena is the facility where the sport of pro-bending is held in Republic City.
The Bending Arena is located on the coast of the bay in Republic City, across the water from Air Temple Island. The arena was built to host the sport of pro-bending where the two teams that bend the three main elements (fire, water, and earth) play to knock one another off of a playing field to score points. There are rules to follow when playing the game such as the amount of water one can bend and how opponents are knocked out of the ring. The sport has reached wide spread fame across the land but not all approve. Tenzin cites the sport as a mockery to the true essence of bending and that it doesn't do anyone any good. Despite opposition, many citizens of Republic City flock to see the sport in action or listen in on the radio when a game is held.
The arena hosts different facilities such as the actual playing field for the benders, audience stands, concessions, locker rooms for players, and even a gym where benders can hone their skills for upcoming matches. It is also the home of brothers Mako and Bolin, two members of the Fire Ferrets that live in the attic of the facility.
