Grotta di Santa Barbara

Southwestern Sardinia

The Grotta di Santa Barbara lies deep within the abandoned San Giovanni mine some 4km west of Iglesias. The walls of the single enormous chamber are pockmarked with dark-brown crystals and white calcite, while stalactites and stalagmites give the impression of a ghostly underground forest. To ensure a spot on a guided tour, it's advisable to book through the tourist office in Iglesias.
