A half-moon shaped cliff face. That’s the first thing you notice about Coveta de sa Mitja Lluna. This isn’t just any cliff. This is a prehistoric copper mine. The only documented prehistoric copper mine in the Balearic Islands.
Coveta de sa Mitja Lluna sits on Illa d’en Colom a privileged location within the Albufera des Grau Natural Park. Imagine Bronze Age miners working here. Their tools simple. Their methods ingenious.
The story of Coveta de sa Mitja Lluna begins long ago. In 2007 researchers started searching for evidence of prehistoric copper mining. Ten years later they discovered this remarkable site. Excavations revealed a trench carved into the rock. This trench likely followed a copper vein running parallel to the cliff. It was hidden under rubble until archaeologists uncovered it.
The work at Coveta de sa Mitja Lluna didn’t stop there. In 2012 and 2014 more explorations confirmed its Bronze Age origins. Archaeologists found ceramic remains. These fragments though small tell a significant story. They along with radiocarbon dating place the mine firmly in the Bronze Age.
But the ceramics weren’t just about pottery. Animal bones were also found. This suggests the miners ate and drank here. The mine itself was remarkably preserved. There are no later exploitations. The mine remains largely untouched just as the last prehistoric miners left it.
The tools used at Coveta de sa Mitja Lluna are fascinating. Many are made from carefully selected pebbles. These pebbles came from Punta des Macs a cove about 750 meters away. Some tools were larger hammers used with two hands. Others were smaller one-handed tools.
The presence of these tools suggests a mineral crushing and selection process took place near the mine. No permanent settlements have been found on Illa d’en Colom. It is possible the miners created seasonal camps. These temporary structures would have been simple and easily missed.
The copper from Coveta de sa Mitja Lluna had a far-reaching impact. Analysis suggests it was a significant source of copper for the Balearic Islands. It even reached Mallorca and the Pitiusas. This shows the interconnectedness of the islands. It also reveals that despite their isolation these communities weren’t cut off from the wider Mediterranean world.
Coveta de sa Mitja Lluna is more than just a mine. It’s a window into the past. It offers a glimpse into the lives of the Bronze Age miners who worked here. Their ingenuity and skills are truly remarkable. It is a unique site worthy of respect and further study.
