Le Mas-d'Azil (in French pronounced as /lə mas dazil/; Occitan (post 1500);: Lo Mas d'Asilh) is a commune in the Ariège department in southwestern France, containing a cave that is the typesite for the prehistoric Azilian culture. The Grotte du Mas d'Azil (sometimes hyphenated, sometimes not) is a "supersite" with rich remains of human usage from about 30,000 years ago, and is also a key site for the preceding Magdalenian culture. The D119 road runs right through the large cave, which is a natural tunnel 420 metres long and 50 metres high.[2]
