The Temple of Time was located near Castle Town. It was built to protect the Triforce (created by the goddesses of Power, Wisdom, and Courage), from evil ones trying to obtain its power as well as serve as a gateway to the Sacred Realm. The legendary Master Sword and its Pedestal of Time were housed in this temple as well, however they were blocked by the Door of Time.
In Twilight Princess, the temple has become the 6th dungeon in the game and is only accessible in the past. The ruins that the Master Sword had been found in are revealed to be the same Temple of Time of Ocarina of Time. The dungeon the second mirror shard can be obtained in can be accessed by briefly placing the Master Sword in the Pedestal of time, he can climb a staircase to the dungeon.
