To understand the origin of many curiosities of Spain we must keep in mind that the Iberian Peninsula, the geographical territory currently occupied by Spain and Portugal, has been a melting pot of cultures for more than 1.2 million years, at which time it is noted the presence of the first hominids in this area. Since then and until now there have been many kingdoms, empires and religions that have disputed these lands, leaving behind small influences that have forged hundreds of curiosities.
