From National Geographic for Kids: The Great Pyramid was once encased in a dazzling layer of polished limestone and topped with a golden capstone. The casting was stripped away long ago as building material for Cairo.

FACT: Of the seven wonders of the ancient world, The Great Pyramid is the only one left standing.
