The Great Pyramid of Giza is the largest pyramid in the world and remains one of the greatest mysteries. It is the oldest of the Seven Wonders of the Ancient World, and the only one to be largely intact. But how was such an impressive wonder built? There have been many varying construction theories from Egyptologists, with many based on the idea that it was built over a 10 to 20-year period, by moving huge stones and lifting them in to place.
