Niaux Cave, or la Grotte de Niaux is one of the most famous prehistoric caves in Europe. It lies in the northern foothills of the Pyrenees, and is located in Ariège, in the valley of Vicdessos, across the valley from the smaller Grotte de la Vache, in an area rich with prehistoric sites. The huge cave entrance, 55 metres high and 50 metres wide, is at 678 metres above sea level. There are more than two kilometres of galleries, with a hundred or more superb paintings from Magdalenian times, most of which are in the famous ‘Salon Noir’, 800 metres from the entrance. Many of the paintings are done in the classic style of the Magdalenian, outlined in red or black pigment, mostly haematite or manganese dioxide respectively.
