The Great Egyptian Pyramid of Giza.

The Great Pyramid was the tallest structure made by human hands in the world.The monumental tombs are relics of Egypt's Old Kingdom era and were constructed some 4,500 years ago.The pyramid rises to a height of 479 feet (146 metres) with a base of 754 feet (230 metres) and is comprised of over two million blocks of stone.The ancient engineering feats at Giza were so impressive that even today scientists can't be sure how the pyramids were built.Built during a time when Egypt was one of the richest and most powerful civilizations in the world,As the story goes, the pyramid’s architect was Imhotep, a priest and healer who some 1,400 years later would be deified as the patron saint of scribes and physicians.The earliest tomb constructed as a “true” (smooth-sided, not stepped) pyramid was the Red Pyramid at Dahshur.In these decorated tombs you have wonderful scenes of every aspect of life in ancient Egypt—so it's not just about how Egyptians died but how they lived.Tomb robbers before and after the caliph had also visited the pyramid prior to the excavations of the 19th century CE. Whatever treasures the pyramid may have held in the time of Khufu could have been removed at any time from the Old Kingdom onward.
