The Giza Necropolis is the only remaining monument of the original seven wonders of the world.   See the three main pyramids: the Pyramid of Khufu (The Great Pyramid), the Pyramid of Khafre, and the Pyramid of menkaure.  There are also smaller edifices and hidden pyramids in valleys, where the Great Sphinx can be viewed.  This is a protected UNESCO World Heritage Site and a must-see for any travelers in Egypt.
