This artificial cave is made from volcanic rubble and is located in the Bermeja mountain region, 3km outside the City, and is one of the biggest archeological sites within the Archipelago. It owes it name to the four entrances, which lead us into the main hall. In the upper part of this area we can find the so-called “Almogarén”, a place of worship to the Gods of nature. It is made up of numerous caves of which Los Papeles and Las Columnas stand out, as they are of particular historical interest.
