Gava Variscite mine - Parc Arqueológic Mines de Gavá

About Parc Arqueológic Mines de Gavá

The Mines of Gavà (Parc Arqueològic Mines de Gavà) are among the oldest known mines in Europe, dating back more than 6,000 years. This vast Neolithic mining complex is unique because it is the only prehistoric site dedicated to extracting variscite, a rare green mineral used to make jewellery and personal ornaments found across Western Europe.

Archaeological evidence shows that Gavà was an important centre of Neolithic trade. Variscite beads from these mines have been discovered in sites throughout the Iberian Peninsula and beyond. In return, the people of Gavà received goods such as flint blades from Provence (France) and obsidian axes from Monte Arci in Sardinia (Italy). Organic remains, including pollen, have also been recovered, offering valuable insight into the environment and daily life in Catalonia 6,000 years ago.

One of the most significant discoveries is the Venus of Gavà, a partially preserved ceramic figurine found inside one of the mining shafts. The figure features sun‑shaped eyes, a stylised nose, bracelets, and hands resting on a prominent pregnant belly. Its black colour and feminine symbolism suggest a connection to fertility rituals and the belief in prehistoric fertility deities.

When the variscite seams were exhausted, many of the tunnels were reused as burial chambers. Excavations have uncovered skeletons buried with high‑value objects such as flint arrowheads, pottery, and jewellery. The chambers were sealed with stone plugs, possibly to protect the dead or prevent spirits from returning to the living world. Skeletal analysis indicates that adults in the mining community had an average life expectancy of around 30 years.

Variscite and Green Turquoise Mineral

Variscite is a hydrated aluminium phosphate mineral prized for its distinctive green colour, often caused by traces of trivalent chromium. Although sometimes mistaken for turquoise, variscite is typically greener and forms in different geological conditions. Because of its rarity, it has long been valued as a decorative stone.

Across Europe, variscite has been used to create personal ornaments and jewellery since Neolithic times. Archaeological discoveries show that variscite beads from the Mines of Gavà were traded widely, appearing in prehistoric sites throughout the Iberian Peninsula and Western Europe. Its use continued into the Bronze Age and Roman period, but it was not until the 19th century that researchers confirmed that nearly all ancient European variscite originated from just three locations in Spain: Gavà (Barcelona), Palazuelo de las Cuevas (Zamora), and Encinasola (Huelva).

Parc Arqueològic Mines de Gavà History

• More than 6,000 years ago, Neolithic communities in Gavà created an extensive network of mining tunnels covering over 200 hectares. Their goal was to extract variscite, a rare green mineral used to craft beads and jewellery that were traded across Western Europe.
• The prehistoric mine was rediscovered in 1978 during construction work in the Can Tintorer neighbourhood. When an excavator broke through the ground, it revealed the characteristic lattice of ancient mining shafts and galleries, making it one of the most important archaeological discoveries in Catalonia.
• Once the significance of the site became clear, archaeologists began a long‑term excavation and conservation project. A protective structure was built over the mine to allow researchers to study the tunnels, analyse the artefacts, and preserve the unique Neolithic mining system for future generations.
