The early Iberians have left many remains; northern-western Spain shares with south-western France the region where the richest Upper Paleolithic art in Europe is found in the Cave of Altamira and other sites where there are cave paintings made between 35,000 and 11,000 BC. The Rock art of the Iberian Mediterranean Basin (as UNESCO term it) is from the eastern side of Spain, probably dating from about 8000-3500 BC, and shows animal and hunting scenes often developed with a growing feeling for the whole composition of a large scene. Portugal in particular is rich in megalithic monuments, including the Almendres Cromlech, and Iberian schematic art is stone sculpture, petroglyphs and cave paintings from the early metal ages, found all over the Iberian peninsula, with both geometric patterns, but also a higher usage of simple pictogram-like human figures than is typical of comparable art from other areas. The Casco de Leiro, a late Bronze Age gold ritual helmet, may relate to other golden hats found in Germany, and the Treasure of Villena is a huge hoard of geometrically decorated vessels and jewellery, perhaps from the 10th century BC, including 10 kilos of gold.
