There are 3 pyramids in Giza. The Great Pyramid, which at its highest peak is 138 meters, was built for the Egyptian Pharaoh Khufu. Next to it lies a slightly smaller Pyramid of Khafre, Khufu's successor, who is also commonly considered the builder of the Great Sphinx. A few hundred metres further south-west is the Pyramid of Menkaure, Khafre's successor, which is about half as tall. The entire Giza Plateau is believed to have been constructed over the reign of five pharaohs in less than a hundred years.
As the Pyramids have been around for over 4000 years, the city of Cairo is clearly built around them. It was rather odd to be driving through a relatively residential part of town only to turn left and have them staring right at you. The Pyramids are the best known man made structure in the world and truly are a modern marvel. It's amazing to look at them and see the amount of work it took to build them without the use of our every day machinery.
Matt and his dad went down into one of the smaller surrounding pyramids, built for one of the queens. While they weren't supposed to take any photos, the guide took one of the two of them at the bottom.
