Casing stones are largely missing from large pyramids of the Old Kingdom, but a few precious sections remain intact.

At the highest courses of the second-largest pyramid of Egypt (Khafre), the casing stones remain in-place and well preserved.

However, because these stones remain inaccessible and out of sight, nobody has ever taken a survey of their layout.

This video maps the arrangement of these casing stones for the very first time, revealing new insights into how large pyramids were originally constructed.

It’s time for Egypt to fully document every casing stone so that this critical piece of history can be fully understood.
