The Pyramid of Khufu in Giza, the greatest and largest pyramid known to us, I had the chance to walk inside it in 1996. If you find the pyramids mysterious and impressive on the outside which everyone I know does, then the inside will leave you mystified! The pyramid of Khufu is constructed with shafts like this one in the photo above that are perfectly straight and on a large scale connecting in a strange maze that no one seemed to have figured out the purpose of despite many various efforts.
The wooden steps you see in the very old photo I took back then were added to allow tourists to walk up the shaft that leads to the king’s chamber.
It was a very strange feeling being in a such a wonder of the ancient past and thinking only how futuristic it felt.
(writing this post and the next few while away in NYC, so I will have very little to reply to comments, but hopefully will catch up soon :))
