As unexplained mysteries go, the Pyramids of Giza in Egypt really are something special. We still don't really know how the Egyptians built the largest pyramid of all, known as the Great Pyramid of Cheops (or Khufu), some 5,000 years ago. Remember, this was even before the invention of the wheel.
The Pyramid of Cheops is the size of a 40-story building and covers an area big enough to fit 10 football fields in it. More than 2 million stone blocks were used to make the pyramid, each weighing 2-5 tons and cut from a distant limestone quarry on the other side of the Nile. Experts reckon it took 400,000 men some 20 years to complete.

A unique and timeless experience of any trip to Egypt includes crawling through the humid, narrow shafts of these huge structures, all the way up to where the ancient pharaohs' tombs were located. Inside all three pyramids, the huge blocks, some weighing up to 15 tons, are so expertly fit together you cannot fit a knife blade between them.
