Photographer's Note

This is a failed first attempt by ancient Egyptians to construct a perfect, stable pyramid & dates from 2600 BC. It is 105 metres high. Another later failed attempt, known as the black pyramid (1650 BC) nearby, is a crumbling wreck as it was made from clay & mud bricks encased in limestone, rather than stone as seen here. This pyramid had the problem of too much stone, and the weight was too great for the clay and gravel foundations. The centre collapsed during construction and the angle was changed from 54 degrees to 43 degrees as a result. Another later attempt was successful and still stands. It is known as the red pyramid. (2570 BC). The red pyramid is also 105 metres tall and was the tallest man-made structure in the world until the completion of the 2 higher pyramids in Giza. (Khufu, 2560 BC, 146.5 Metres; & Khafre, 136.4 m in 2570 BC). The latter 2 pyramids remained the tallest structures in the world until the completion of Beauvais's St. Pierre Cathedral in the 1570's (152.4 m). The spire of the the cathedral lasted only 70 years and it was not until the Washington Monument (169.16 m) in the 1850's, that the pyramids were again usurped, this time & ironically, by another Egyptian designed form, the obelisk. The pyramids of Giza remained the tallest structures ever built by man for over 4,000 years!
