A cave or cavern is a hollow place in the ground, especially a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground.
Cave paintings are paintings found on cave walls and ceilings, and especially refer to those of prehistoric origin. The earliest such art in Europe dates back to the Aurignacian period, approximately 40,000 years ago, and is found in the El Castillo cave in Cantabria, Spain.
