Aang Memorial Island

Aang Memorial Island is a small island located in Yue Bay. It features a massive sculpture of Avatar Aang commissioned by the Fire Nation some years after the end of the Hundred Year War for display in Republic City, where it stands as a symbol of peace and goodwill. There is a museum that teaches of the past Avatars inside the statue's pedestal.

History
After Korra aided Tarrlok with an assault on an Equalists training base, she publicly challenged the Equalist leader, Amon, to a duel at Aang Memorial Island at midnight. As the clock on the island struck midnight, Amon wasn't there. When Korra eventually gave up the wait, believing he didn't accept, she found herself assaulted and dragged into the museum underneath the statue by several of Amon's henchmen. Korra managed to fight some of them off by raising part of the ground with her earthbending, but she was soon overpowered by their numbers and immobilized by chi blocking. Amon emerged from the shadows and told Korra that he had a plan that would eradicate the world of benders and that he was saving her for last. After Amon knocked Korra, she had a vision for the first time about Aang.

Avatar Aang Memorial Statue
The statue is located on a small island off the shores of Republic City. It depicts an older Aang donned in traditional Air Nomad attire, with the accompanying necklace he wore when Fire Lord Zuko announced the War's end at his coronation. The figure holds a staff with its left hand with the airbending symbol at the upper end, and its left foot rests on a slightly higher surface in the form of a lotus flower. The pedestal on which its other foot stands is an octagon with an upturned tip at each vertex surrounded by railings, leaving an opening at the back of the sculpture, where a paifang gate connects the pedestal with a road linking the island to a dockyard.

Trivia

 * Aang's statue, as well as its role as a symbol of peace between two nations, is a reference to the Statue of Liberty. The latter was a gift from France to the United States and was meant to commemorate the centennial of American independence.
