Tenerife in the Canary Islands is well-known as a holiday destination, but many tourists visit the island unaware that there are pyramids there and an ongoing mystery. Who built the pyramids, when were they constructed, and why? There are three theories and an ongoing debate.
Pyramids of Güímar

Güímar is a town in the south of Tenerife and it is the location where six of the pyramids are to be found. They are safely housed today in the Ethnographic Park , which was set up by the explorer Thor Heyerdahl , with the financial backing of shipping magnate Fred Olsen.
