What the secret of the pyramid of Egypt?

Giza is most famous as the location of the Giza Plateau, the site of some of the most impressive ancient monuments in the world, including a complex of ancient Egyptian royal mortuary and sacred structures, including the Great Sphinx, the Great Pyramid of Giza, and a number of other large pyramids and temples. Giza has always been a focal point in Egypt's history due to its location close to Memphis, the ancient pharaonic capital of the Old Kingdom. Its St. George Cathedral is the episcopal see of the Coptic Catholic Eparchy of Giza.
