Neanderthals of Gorham's Cave

Sea caves at the foot of the Rock of Gibraltar's eastern cliffs hold layers left by Neanderthals over more than 100,000 years: hearths, stone tools and the bones of seals, birds and shellfish they ate. A cross-hatched pattern cut into the rock of Gorham's Cave, at least 39,000 years old, is read by many as Neanderthal abstract art. The caves may have been among their last refuges.
