Did the Prism Stone of the Great Pyramid exist?

The junction of corridors within the Great Pyramid is a unique and mysterious feature that is greatly misunderstood. This key point of entry was required to gain access to the upper chambers where the burial of the pharaoh and his great treasures would be located.

The corridor junction is completely sealed with three enormous granite blocks that still remain in their final position. This method of closure for the upper chambers of the pyramid is a controversial subject because it does not disguise this point of entry.

This video takes a close examination of the physical evidence and demonstrates that pyramid defense features of the Old Kingdom cannot be judged by the standards of later pharaohs or explorers who ventured inside.
