Imagine a monument so historically astonishing that it was previously considered among the seven wonders of the world. Journey to the Pyramids of Giza, named after the area of northern Egypt, they were erected on, near the Nile River, these pyramids were built nearly 4,500 years ago. They are comprised of three pyramids: Khufu or the Great Pyramid, Khafre and Menkaure corresponding to the kings for whom they were built. In ancient times, pyramids were built as graves for the pharaohs and kings to be buried with their earthly possessions such as gold and other riches, since they were considered to become Gods in the afterlife. Khufu is the oldest and tallest pyramid to be built, towering 147 metres above the plateau. On the other hand, the second pyramid to be built was that of Khufu's son, Khafre. Along with the pyramid, Khafre built The Sphinx, a mysterious limestone monument shaped like a lion with a Pharaoh's head, guarding the three pyramids. The way Pyramids were built remains until today a huge scientific wonder. How ancient Egyptian engineers mastered moving and transporting tonnes of heavy limestone rocks, let alone use them to build these hundreds of metres tall structures, remains a mystery.
