<human>:  Do the Egyptian pyramids look the same from outside as they did when new?
<bot>: No, the Egyptian pyramids are ancient pyramid-shaped masonry structures located in Egypt. They do not look the same from outside as they did when new. When originally built, the Great Pyramids had a thin surface of limestone covering the bricks, making them shine in the sun. Over the centuries, the limestone layer has been removed by thieves and erosion, exposing the more common stone bricks underneath, not the limestone.
