Rock Art of the Mediterranean Basin on the Iberian Peninsula. The group of over 700 sites of prehistoric Rock art of the Iberian Mediterranean Basin, also known as Levantine art, were collectively declared a World Heritage Site by UNESCO in 1998. The sites are in the eastern part of Spain and contain rock art dating to the Upper Paleolithic or (more likely) Mesolithic periods of the Stone Age. The art consists of small painted figures of humans and animals, which are the most advanced and widespread surviving from this period, certainly in Europe, and arguably in the world, at least in the earlier works. It is notable for the number of places included, the largest concentration of such art in Europe. Its name refers to the Mediterranean Basin; however, while some sites are located near the sea, many of them are inland in Aragon and Castilla–La Mancha; it is also often referred to as Levantine Art (meaning "from Eastern Spain", not the Levant region).
