Hokage Rock

The Hokage Monument, or Hokage Mountain, is the most representative trait of Konohagakure. It is a mountain that has had the faces of all the Hokage carved into the stone. During the first episode, Naruto Uzumaki painted the faces of the four Hokage as a joke, and revealed that he planned to surpass them, stating that his face will someday too be in the monument. He also did it to grab attention, as the people of Konoha despised him for having the Nine-Tailed Demon Fox sealed inside him. At the beginning of the series, the Monument had the faces of the First Hokage, the Second Hokage, the Third Hokage, and the Fourth Hokage. During the timeskip, the face of the Fifth Hokage was added to the mountain, as Naruto found out in the first episode of Naruto Shippūden.

The Monument has been important during many parts of the story, mostly because of its symbolism:
 * During Orochimaru's attack on Konoha, The Third Hokage's face cracked, giving a bad omen.
 * During the Konoha 11 filler arc, the climax occurred at the Hokage Monument, symbolizing that the future of the village was safe in the hands of the Genin.
 * During Pain's Invasion of Konoha Arc, after using Shinra Tensei, most of the village was destroyed, but the Hokage Monument endured the gravitational attack. After his return, Naruto was confused about where he was. But, after seeing the Hokage Monument, he realized that the ruins he was surrounded by were the remains of Konoha.

The Konoha Library was built into the mountain of the Hokage Monument and also endured Pain's attack.

Trivia
