La Cotte de St Brelade is a Paleolithic site of early habitation in St Brelade, Jersey. Cotte means "cave" in Jèrriais. 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 hominim 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.
At that time, with sea levels slightly below those at present, Jersey was part of Normandy, a peninsula jutting out from the coast, and La Cotte would have been a prominent landmark on the dry plain that linked Jersey to the French mainland. It was not until after the last Ice Age that the sea eroded the coastline, separating first Guernsey, then Jersey and finally the Écréhous from the mainland.
Remains of fire was found in La Cotte. In fact, the earliest dates obtained for artifacts at the site (238,000 BP) come from thermoluminescence dating of burnt flint.
