Contrary to popular belief, the world's largest pyramid is located in Mexico, not Egypt.
Egyptian pyramid workers were paid with 4 liters (1 gallon) of beer per day. Herodotus, the Greek historian, spread a myth that the pyramids were built by slaves, but in reality, they were built by paid laborers.
For 3800 years, the tallest man-made construction in the world was the Great Pyramid of Giza. The great pyramid of Giza still contains many passageways that are yet to be explored.
