Great Pyramid of Giza and Sphinx, Egypt As one of the most memorable and prominent Seven Wonders of the Ancient World, the Great Pyramid of Giza is one of three pyramids in the area, but is by far the oldest and largest – it is reputed to have been built approximately 2,500 years ago and currently stands at 455.22 feet tall. Combined with the beautiful statue that is the Sphinx, the 241 foot long sculpture that is reputed to have been built in 2,500 years BC, they are two of the most recognisable monuments on earth.
