5) Pyramid Decoration
Hieroglyphs cover the interior of many Ancient Egyptian tombs and palaces. But contrary to myth, the pyramids are relatively undecorated. Indeed, until recently the pyramids at Giza were thought to be absolutely bare inside. This supposition was shattered when hieroglyphs were found behind a secret door in the Great Pyramid a few months ago. Also, the pyramids were not all limestone-colored 4000 years ago: some sections, such as interior pillars, were painted red or white. This basic paint and hidden writing still leaves the pyramids extremely austere; it is their architecture that cements the pyramids as the oldest and most popular stone buildings in the world.
