Naka Shrine

The is a shrine in Konohagakure. In the main hall, beneath the seventh tatami mat from the far right, is a secret meeting place of the Uchiha clan. There stands a stone monument which contains the clan's secrets and can only be read with specific dōjutsu. The Rinnegan is able to completely decipher the contents of the monument, while the Sharingan and Mangekyō Sharingan are only able to partially decipher it. Recorded there are the secrets of the Mangekyō Sharingan, the story of the Sage of the Six Paths and the Ten-Tails. Madara also noted that the secrets of his body were also there. Also written on the tablet, is the story of Kaguya Ōtsutsuki and the Shinju. However, certain facts and details were forged by Black Zetsu, Kaguya's will. In order to access the main hall, a sequence of seals is required to remove the stone that lays atop the entrance way. The seal itself has the Sharingan in the middle and is encircled with seal formulas.

The upper level of the shrine was destroyed during Pain's assault on Konoha, though the secrets hidden below remained untouched and was later accessed by Taka and Orochimaru during the Fourth Shinobi World War.
