I'm not sure this is so. My understanding is that cave art attributable to Neandethals have been found in the Loire and in Spain. The attribution is based on dating the paint used, which apparently (or allegedly) pre-dates homo sapiens' arrival in Europe.
The famous individual buried in Shanidar cave surrounded by pollen is often cited as an example of Neanderthal intentional burial practices, indicating symbolic thought and ritualistic behaviors.
