A great page of history: here the Nuragic people extracted the essential component of bronze, which they melted down to shape statuettes, tools, jewellery and weapons. Funtana Raminosa, one of the richest copper deposits in Europe, is one of the eight areas that make up Sardinia’s geo-mineral park, listed among UNESCO’s Geoparks. It is an open-air and underground museum, which can be visited by booking, with working machinery that was state-of-the-art at the time and is still in excellent condition. The 'copper well' covers an area of about 150 square kilometres and is ten kilometres from Gadoni, a mountain village in the Barbagia di Belvì area, whose history, economy and identity it represents.

Since prehistoric times, it has been a key player in Mediterranean metallurgy, and after the Nuragics, the site was exploited by the Phoenicians and Carthaginians, then by the Romans: tools, an ingot and the remains of a miner dating from the Imperial age have been found. Two of the current 150 'tunnels', the Phoenician and Roman tunnels, date back to the ancient heritage.
