 The cave is also known as "Lé Creux ès Fées" (The Fairies' Cave).Neanderthals lived there at various times between around 250,000 years ago and after 48,000 years ago—making it the earliest known occupation of the Channel Islands by a hominin species, and also possibly one of the last Neanderthal sites in northwestern Europe.It is the only site in the British Isles to have produced late Neanderthal fossils.
