Pyramids of Giza, Egypt

The Great Pyramid of Giza is the most substantial ancient structure in the world - and the most mysterious. According to prevailing archaeological theory - and there is absolutely no evidence to confirm this idea - the three pyramids on the Giza plateau are funerary structures of three kings of the fourth dynasty (2575 to 2465 BC).It's base covers over 13 acres and its volume is around 90,000,000 cubic feet. You could build 30 Empire State buildings with its masonry. It is 454 feet high which is equivalent to a modern 48-story building.
