Expedition to Spain. Pyramids of the island of Tenerife

Look carefully. These are whole pyramids, here is nothing under the ground. In front of us are military fortifications that protect something. The question is what they protect?

On the other side we see two entrances to the gorge. According to the legend this is an entrance to “another world”! That’s what they say in Tenerife …
In fact in these canyons are memorial cemeteries of mummies in the rocks of the canyons. Above all there is the volcano Teide!
