Temple of Light

The Temple of Light was built by Rauru during the Era of Chaos in order to protect the Triforce. It has been depicted several times, most notably during the events of The Legend of Zelda: Ocarina of Time, The Legend of Zelda: Tears of the Kingdom, and The Legend of Zelda: A Link Between Worlds. In Hyrule Historia, the Temple of Light was built at the center of the Sacred Realm^[1].

Depictions

Ocarina of Time

The Temple of Light is depicted as a serene location featuring a central pedestal with the same symbols as the Sage Medallions. Small hexagonal pedestals can be found surrounding the main pedestal with each emanating a luminous blue color.

A Link Between Worlds

During the process of rescuing the Sages, Link visits the Temple of Light several times. It is very similar to its counterpart in Ocarina of Time, but with a notable difference in that the individual sage pedestals each have a Hylian letter on them instead of Sage symbol, spelling out the word "Courage" in a circular fashion.

Tears of the Kingdom

At the end of the Seal War, Ganon was sealed in a place that came to be known as the Imprisoning Chamber. In The Legend of Zelda: Tears of the Kingdom Masterworks, it notes that the Imprisoning Chamber once served a different purpose and that it is part of the Temple of Light complex ^[2]. The implications that the Temple of Light are beneath the castle would imply that the Sacred Realm is actually located in a subterranean area. The Temple of Light was built directly over top of the ruins of the Sealed Temple and by extension it would imply that access to the Sacred Realm would have been at the Temple of Hylia complex.
