At the first 1900 photo we can clearly see two holes in the Great Sphinx (Giza, Egypt). One is at the top of the head and the other right behind the neck. With both science about six meters down and suddenly ending. Besides, there is another hole at ground level at the tail, which leads a few meters below ground level.

What were these corridors for? What was their purpose? Did any of them serve as the entrance to a secret room that contained the knowledge of the mythical Atlantis?
