History

Gorham’s Cave was first noted scientifically when Captain A.E.H. Gorham of the Royal Munster Fusiliers explored it while stationed in Gibraltar in 1907, reporting animal bones and artefacts. Systematic excavation began in the 1950s and has continued, with increasing sophistication, ever since. The discovery of Neanderthal occupation layers dated to 24,000–30,000 BCE — confirmed by electron spin resonance dating and other modern techniques — was scientifically revolutionary: it pushed the survival of Neanderthals far beyond all previous estimates.

Vanguard Cave, excavated from the 1990s onwards by Clive Finlayson and the Gibraltar Museum team, produced some of the most significant evidence. Hearth deposits showed that Neanderthals were cooking shellfish — mussels, limpets, and clams — as well as seals, monk seals, and what appears to be dolphin, demonstrating a sophisticated coastal foraging strategy. Scraped and cut eagle and vulture bones suggested feathers were being removed intact — implying their use for decoration or adornment, a form of symbolic behaviour previously thought exclusive to anatomically modern humans.

In 2012, researchers announced the identification of what may be the only known example of Neanderthal rock art: a crosshatch pattern engraved into the bedrock of Gorham’s Cave, covered by undisturbed Neanderthal deposits and therefore definitively pre-dating modern human arrival in the area. The interpretation remains debated in the scientific community.

The later archaeological layers of the caves reveal post-Neanderthal use: Phoenician sailors and merchants left votive offerings from approximately the 8th century BCE, followed by Carthaginian and Roman deposits, testament to Gibraltar’s enduring significance as a landmark for Mediterranean seafarers.
