There are remains of at least 70 still standing in Egypt and Sudan, and archaeologists know of about 88 more that no longer exist.
The pyramids were made to last more or less forever.
In actuality, they’ve done a pretty good job of holding up, considering that they were built between 2700 and 1000 B.C.
However, the pyramids’ designers didn’t account for one human foible in their bid for monumental immortality: that if something is lying around not being watched, someone’s going to try to take it.
Whenever later Egyptians needed chunks of rock for construction, they’d pry pieces off the local pyramid.
This apparently went on for centuries, leaving many of the pyramids mere shadows of what they once were.
The pyramids at Giza, to give a notable example, have lost all but a few blocks of the polished limestone that once made them shine bright white in the sunlight.
The Great Pyramid even lost 31 feet off its height.
The most complete, best-preserved, least-vandalized pyramid? It stands at Saqqara, near Cairo.
Make your reservations before it disappears.
