Located in the holy city of Zion, the Temple was constructed by Maruyama Chihiro and the other survivors of the Operation Ark command crew, being built only after Eric Langhorne and most of his inner circle had been killed by Pei Kau-yung at the beginning of the War Against the Fallen. The Temple served as a command post for Chihiro and his supporters, most notably Androcles Schueler, and was built with the use of highly advanced construction materials.
When Merlin Athrawes discovered the presence of active energy signatures beneath the Temple in the Year of God 890, he cautiously attributed these signatures to the structure's "miraculous" climate control systems, but decided that using the high tech surveillance systems available to him within a certain proximity of the Temple would constitute an unacceptable risk of detection.
