Temple of Time

The Temple of Time is the temple located in Hyrule with the most reverence regarding it from game-to-game. The form of the temple changes between games, but the Master Sword is typically housed in this building in most of its depictions, which is also shown to be used as a key to traverse time. Even in games where the temple is depicted to have decayed and fallen, the Master Sword is still within its pedestal.

The Legend of Zelda: Ocarina of Time
In The Legend of Zelda: Ocarina of Time, the Temple of Time is near Hyrule Castle. The temple itself was dignified and sat in the middle of a well-maintained garden. At the rear of its main hall stood the sealed Door of Time. Beyond that, the Master Sword (which was the key to the Sacred Realm) sat in the pedestal of time.

The Legend of Zelda: Twilight Princess
In The Legend of Zelda: Twilight Princess, a dense forest prevents access to the Temple of Time, but the Master Sword is still deep inside the temple. Link journeys to thes acred grove that has grown in place of the decayed temple. Using the Master Sword as a key, Link is able to walk into the past, where the temple still stands and contains the technology of the Oocca.

The Legend of Zelda: Skyward Sword
In The Legend of Zelda: Skyward Sword, Link finds one of the Temples of Time in Lanayru Desert and another in the Sealed Temple. These are both marked by gates of time. Each gate was operated by way of the divine force from within the Master Sword, The Temple of Time was destroyed after Link and Impa escaped Ghirahim through it, with the Goddess's Harp in tow. The Sealed Temple did not survive.
