Entering the Great Pyramid was exciting, the narrowness of the ascending hundred foot passageway, the height of the metal rung ladders and the closeness of the air took my breath away. You emerge from the Grand Gallery into the third chamber that has five chambers above it. The five chambers support the upper part of the pyramid so that its weight does not crush the third chamber and collapse the pyramid. To stand in the spot directly below the apex you gain an understanding of the power and scope of your visit to the pyramid. Built approximately 2560 BC the sides of the Great Pyramid face the four cardinal points. The Great Pyramid is one of the Seven Wonders of the Ancient World.
