The caves have layers with flint tools from the Mousterian, and later cultures. They were seasonally occupied by nomadic groups of people during the Upper Palaeolithic and Mesolithic periods. Evidence of Neolithic, Bronze Age, Roman and post-medieval activity has also been found there. There is evidence of Neanderthal occupation 50,000–60,000 years ago, a brief Gravettian occupation around 32,000 years ago and use of all the main caves during the Magdalenian around 14,000 years ago. The site is open to the public and has a visitor centre with a small museum of objects.
