The Pyramids of Guimar, which are located in the municipality of the south-east of Tenerife, represent a real mystery, perhaps the Egyptian piramadi. No one has yet managed to find an explanation of their usefulness, but above all no one can figure out who they were built. The pyramids are astronomically to project their shadow during the summer and winter solstices. The mystery is that the Guanches, the ancient inhabitants of the Canary Islands, were not at an advanced people, indeed. They lived in caves, they argued to the pasturelands and used garments made with goat skin. . How could they build such sophisticated pyramids and so similar to those found in Egypt, Mesopotamia and South America?
