The Last Bastion of the Hominins: Deciphering the 40,000-Year Sealed Silence of Gibraltar

The limestone cliffs on Gibraltar’s eastern face hold caves that have sheltered humans for more than 100,000 years. But one chamber, discovered in 2021 at the back of Vanguard Cave, had seen no light for at least 40 millennia. When researchers from the Gibraltar National Museum finally breached its sediment seal, they found bones of lynx, hyena, and vulture resting exactly where they had fallen, alongside the shell of a whelk that someone had carried deep into the darkness.

The chamber’s contents offer a moment frozen in time from the final chapters of Neanderthal existence. But the larger story of who occupied these caves, and when they vanished, has become one of the most contested questions in paleoanthropology. The Gorham’s Cave complex, designated a UNESCO World Heritage site in 2016, contains evidence that some Neanderthal populations may have survived in southern Iberia thousands of years after their disappearance elsewhere in Europe.
