Pro-bending is the most popular sport in Republic City, and official pro-bending matches are held in the city's Pro-bending Arena. As a testament to the sport's popularity, this building has a golden appearance and is lit at night, making it a prominent city landmark. The arena is spacious enough to hold the pro-bending ring on which the contestants compete, a large pool of water far below the ring, and seating for the great number of spectators that attend each game. The arena is one of Republic City's most renowned cultural marvels, and people from all over the world come to visit and watch the world's greatest benders compete.
After the Pro-bending Tournament was completed, the Equalists attacked this arena, leaving the roof and the pro-bending ring heavily damaged. Following the attack, in which the championship team was stripped of their bending by Amon, the arena was closed indefinitely. However, within the six months following the end of the Equalists' revolution, the arena was re-opened, allowing pro-bending matches to resume.
