The prehistoric art of Spain had many important periods-it was one of the main centres of European Upper Paleolithic art and the rock art of the Spanish Levant in the subsequent periods. In the Iron Age large parts of Spain were a centre for Celtic art, and Iberian sculpture has a distinct style, partly influenced by coastal Greek settlements. Spain was conquered by the Romans by 200 BC and Rome was rather smoothly replaced by the Germanic Visigoths in the 5th century AD, who soon Christianized. The relatively few remains of Visigothic art and architecture show an attractive and distinct version of wider European trends. With the Umayyad conquest of Hispania in the 8th century there was a notable Moorish presence in art specially in Southern Iberia. Over the following centuries the wealthy courts of Al-Andalus produced many works of exceptional quality, culminating in the Alhambra in Granada, right at the end of Muslim Spain.
