- from Pyramids
Building a pyramid was difficult and dangerous, and it took a highly organized society to do it.
Thousands of skilled and unskilled workers were needed. To build the Great Pyramid at Giza, one huge stone block must have been quarried, shaped, and smoothed every two minutes for 23 years!
Building plans showing how the pyramids were built have never been found. However, experts use present knowledge about construction to make some intelligent guesses.
