Gavà Mines

Six thousand years ago, people here risked their lives underground not for food, not for tools, but for beauty. The Gavà Mines are Europe’s oldest known gallery mines — and the only prehistoric mining complex anywhere dedicated purely to extracting a gemstone for jewellery.

Mined for beauty, not survival

Starting around 3800 BC, Neolithic communities dug more than a hundred shafts and galleries into the hills above what’s now Gavà, hunting for variscite — a rare green phosphate mineral prized purely for its colour, worked into beads and pendants rather than tools or weapons. This wasn’t a subsistence operation. Archaeologists consider it the earliest known example of large-scale mining conducted specifically for ornamental purposes anywhere in Europe, and finished variscite beads from these exact shafts have turned up in burial sites and trade networks stretching across the western Mediterranean, exchanged for goods including flint blades from Provence and obsidian from Sardinia. It took nineteenth-century researchers to confirm what ancient traders already seemed to know instinctively: nearly all prehistoric European variscite traces back to just three Spanish sources, and Gavà was the largest by far.

A skull, a goddess, and mines turned into tombs

The human story preserved underground here is genuinely unsettling in places. One recovered skull shows clear evidence of trepanation — a deliberate surgical hole cut into living bone, one of prehistory’s most extreme medical interventions. Deep inside one shaft, excavators found the Venus of Gavà, a partially preserved ceramic fertility figurine left in a working mine rather than a settlement or shrine. And once individual shafts were exhausted of variscite, communities didn’t simply abandon them — some were deliberately repurposed as burial chambers, turning spent mineral extraction sites into a final resting place for the people who may have once worked them.
