Some people estimate 70 million mummies, but I think that's an underestimate. Mummification was carried out in Egypt, as I mentioned, for over 3,000 years. I'm sure more human mummies were made during this time period. If you look at animal mummies, several hundred thousand mummies have been found even in one cemetery. Countless mummies have been destroyed by tomb raiders seeking treasures within their linen wrappings.
The Pyramids of Ancient Egypt were built as tombs for Kings (and Queens), and it was the exclusive privilege to have a Pyramid tomb. However, this tradition only applied in the Old and Middle Kingdoms. Today there are more than 93 Pyramids in Egypt; the most famous ones are those at Giza.hafre's son, Menkaure, built the smallest of the 3 main Pyramids on the Giza Plateau. This one was only a mere 65.5m (215ft) tall, nowadays 62m (203ft), with sides of only 105m (344ft) and an angle of 51.3 degrees.
