Underground Chapel (Anime)

The Underground Chapel is located beneath a chapel in a village near the Reiss family estate. It is a sacred location and the walls are composed of a luminescent ore that is thought to have been created by some form of Titan power. It is here that the royal family's power is passed down from vessel to vessel, for generations.

Description
Above ground, it looks and functions like any other church. Below the altar, hidden by a rug, is a stairway that leads to a large underground cavern. The cavern was created by the First Reiss King, and contains hardened crystal walls that produce their own natural illumination.

The Uprising arc
After having a vision of Frieda Reiss, Eren Jaeger wakes to discover himself gagged and restrained on a platform overlooking a large crystal cavern. He spots Historia approaching below him while wearing a pure white dress.
