THE SPHINX1
The Sphinx is one of the best-known monuments on Earth and dates back over 4,500 years to the Old Kingdom and the time of king Khafre-builder of the second largest pyramid on the Giza plateau2 on Cairo's outskirts3. The Sphinx is about 73.5 metres in length. It was originally sculptured from a limestone4 and, for most of its history, the Sphinx has been at least partly covered in sand.
