Neanderthal Tools Discovered in Olopte Cave
Archaeologists have uncovered the first evidence of Neanderthal presence in the Cerdanya valley, following the discovery of stone tools in the Cova C d’Olopte near Isòvol. The tools, crafted using the Levallois technique, are a hallmark of Neanderthal communities and confirm that these early humans traversed the Pyrenees far earlier than previously established. Xavier Mangado, lead researcher and archaeologist at the University of Barcelona, explained that the finds are based on lithic remains, including worked stone fragments and tools. "The most important aspect is that some of these pieces were made using the Levallois method, a distinctive stone tool production technique from the Palaeolithic period associated with Neanderthals," he said.
Pushing Back Human Occupation by Tens of Thousands of Years
Prior to this discovery, the earliest known evidence of human occupation in the valley dated to around 22,000 years ago, based on findings at the Montlleó open-air site. The Olopte tools, however, suggest human activity in the region significantly earlier, though the exact date remains undetermined. Researchers are preparing sediment samples for luminescence dating, a method capable of reaching the deep time scales relevant to Neanderthal occupation, unlike radiocarbon dating, which is ineffective beyond around 50,000 years. Results are expected in the coming months.
Cerdanya as a Natural Mountain Corridor
The geographical position of Cerdanya, a broad high-altitude valley at the heart of the eastern Pyrenees, made it a natural corridor for prehistoric movement between northern and southern slopes. Mangado stressed that the Pyrenees were not an impermeable barrier: "The Cerdanya is a zone of passage, and the Segre river is an important corridor." This theory is reinforced by the discovery of a tool made from jasper sourced from the foothills of the Canigó, on the northern (French) side of the range. The material, identified from terraces of the Têt river, is not found locally in Cerdanya. Its presence indicates either direct movement from the French side or long-distance exchange networks. "This tells us that at least some of these groups came from or had contact with the French side. It’s clear evidence of mobility," Mangado said.
Further Research to Uncover Ancient Activity
The excavation project, funded by the Generalitat’s Department of Culture through its Archaeology Service, will continue for the next four years. It involves the University of Barcelona’s Seminari d’Estudis i Investigacions Prehistòriques (SERP), Pompeu Fabra University, and the Universitat Rovira i Virgili through IPHES-CERCA. Researchers aim to uncover more tools, animal remains, combustion structures, possibly hearths, and, potentially, human fossils. They also seek to determine whether the cave saw multiple episodes of occupation. "We want to know how many occupation episodes there were, their age, and what these groups were doing when they were here," Mangado added.
Vandalism Response and Site Protection
The site was vandalised in 2025, prompting the Generalitat to secure the area before resuming excavations. The incident highlights the fragility of archaeological sites, where sediment disturbance can destroy irreplaceable scientific data. "When an archaeological site has been altered, you must protect it. The information within the sediments is unique and cannot be recovered," Mangado noted. The discovery not only reshapes understanding of prehistoric movement in the Pyrenees but also reinforces that Neanderthals were closely related human cousins to Homo sapiens, with whom they interbred. Modern non-African populations retain traces of Neanderthal DNA. "We’re not talking about an alien species. We’re talking about relatives," Mangado said.
