Spain preserves some of the richest late Neanderthal evidence in Europe, with key sites such as Sima de las Palomas del Cabezo Gordo (Murcia), Cueva de Valdegoba (Castilla y Leon), and Cueva del Boquete de Zafarraya (Andalusia). These caves, dating between 53,000 and 44,000 BC, highlight both the adaptability and the persistence of Neanderthals in Iberia during their final millennia. At Sima de las Palomas, archaeologists uncovered articulated Neanderthal skeletons, suggesting possible burial practices. The site also yielded Mousterian tools, animal bones, and evidence of fire use, indicating a versatile lifestyle in Mediterranean environments. In contrast, Valdegoba Cave in northern Spain preserves more fragmentary remains, but these confirm the robust physical build of Neanderthals and provide evidence of repeated cave use as a base for hunting and resource gathering. Finally, Zafarraya Cave in Andalusia is particularly famous because its remains, including a partial mandible, date to about 44,000 years ago - among the latest Neanderthal fossils in Europe. Taken together, these Spanish sites show that Neanderthals persisted in Iberia even after disappearing elsewhere in Europe, suggesting the region acted as a refugium, a last stronghold where small groups survived in relative isolation.
