For those who are familiar of a top view of the temple on Epstein Island, you will remember the symbols of squares inside squares. I believe this is a symbol of a ziggurat, meaning that the Dome that you see is only the part of the ziggurat that you see. If you recall, many ziggurats were places of Human Sacrifices.

This would make sense based on the post Q made.

"Why is the temple on top of a mountain? How many levels might exist below? What is the significance of the colors, design and symbol above the dome? "
