With 42 painted figures and 260 other images carved into the rock, La Roca dels Moros del Cogul, in Les Garrigues, is one of the most outstanding and best-conserved rock-art sites in Catalonia. Amongst the most outstanding scenes depicted are a hunting scene and a phallic dance, an exceptional representation of a ritual event, which lends credence to the idea of the cave being a place for religious practices.

This area of Les Garrigues has been inhabited continuously by humans since the Paleolithic period and the cave was used for about 5000 years as a place of worship. The last hunter-gatherers (8th - 5th millennium BC) left behind paintings known as Levantine art. Later, from the 5th- 2nd millennium BC, Neolithic groups covered up the reliefs in the rock to draw representations of their own beliefs (diverse representations that fall within the classification of schematic art ). Researchers have also identified later inscriptions from the Iberian and Roman periods, though many are illegible.
