Temple of Light

The Temple of Light (alternatively known as the Light Temple when compared to other temples) is the only known elemental temple that is not located directly within Hyrule; instead, it lies in the Sacred Realm and is closely linked to the Temple of Time. . This is the reason why the Prelude of Light warps Link to the Temple of Time instead of the Temple of Light. It was the resting place of the Triforce before Ganon stole it. The Temple of Light only appeared in Ocarina of Time, and only one of its chambers is visited: the Chamber of Sages where the Sages meet. As the Chamber also appears within the Pyramid in A Link to the Past and the Pyramid is shown in the background story for the Golden Land, it may be assumed that the the Pyramid is in fact the Light Temple.

Though Link in Ocarina of Time is not able to visit the Temple of Light on his own, he is often warped to the Chamber of Sages. The first time was when he took the Master Sword from the Pedestal of Time and opened the gate to the Sacred Realm. Rauru, the Sage of Light at that time, kept him in suspended animation within the Temple of Light until Link would be old enough to become the Hero of Time. After that, every time Link awakened a Sage, he and the Sage were teleported to the Chamber of Sages to bestow their powers to Link in form of a medallion before returning to Hyrule again.

Trivia

 * The music in the Chamber of the Sages is a looped version of the music that plays when Princess Zelda tells Link the Legend of Hyrule earlier in the game.
 * It has been shown via emulation hacks (the debug rom) that the platforms in the background are, in fact, solid, and with aid of another hack it's possible to "visit" them. It is unknown whether this is a trace from the beta version of Ocarina of Time or just a glitch.
 * Considering its location in relation to the Temple of Time, the Temple of Light may be dungeon Link encounters within the Temple of Time in The Legend of Zelda: Twilight Princess. This is supported by the fact that the emblem of the Light Medallion is everywhere in the dungeon, on switches and even on the floor of the room where the Darknut is fought. Strangely, in Twilight Princess, the room where the Sages are gathered has been shifted to the Arbiter's Grounds in the Gerudo Desert, which is believed to have been the Spirit Temple in Ocarina of Time.
 * Despite not being explored, the temple still receives recognition as the "Light Room" in Ganon's Castle.
