The ancient Egyptians took pyramid construction to new heights along the Nile River in northeastern Africa 5,000 years ago, but they weren’t the only civilization to build massive pyramid-shaped monuments (for even to mummify their dearly departed, which other ancient cultures also practiced). Pyramids were the most structurally sound buildings that could be constructed out of stone – as long as a civilization had sufficient rocks to quarry and the manpower to move them. Cultures all over the world built pyramids throughout history. They came in different forms and functions.
