Among the archaeological findings made in Tenerife in the 20th century, one of the most striking is, without doubt, the discovery of Guanche mummies in caves and crags on the Island. The Guanche people would embalm their deceased and preserve them in caves that were difficult to access. It has been found that they used different mummifying techniques, which are believed to depend on the social rank of the time or on their religious beliefs. The process of embalming a body in the Guanche culture is similar to that of other ancient civilisations.
According to the research carried out in studying the Guanche mummies, these burials were used at least from the 3rd century until the conquest of the Canary Islands. A number of these mummies can currently be seen at the Museum of Nature and Mankind in Santa Cruz de Tenerife, which boasts one of the best systems for preserving such archaeological remains.
