PC: Kevin Hutchinson A mummy always reminds of thousands of years old pharaohs and pyramids but many civilizations including Incan, Australian Aboriginal, Aztec, African etc have practiced several types of mummification processes to preserve bodies. Guanajuato mummies are world famous for its terrifying looks. It actually is a collection of hundreds of mummies which were mummified naturally during late 19th century. In 1850s a worldwide cholera outbreak caused thousands of deaths and soon underground cemeteries in Guanjato were running out of space to accommodate bodies. So the authorities had to build walled crypts above ground and in this warm arid environment bodies started a natural mummification process.
