The caves of Toirano are located a few kilometers from the village of the same name, in the hinterland of Borghetto Santo Spirito in the province of Savona. The karst complex consists of many cavities, two of which, the cave of the Bàsura (or cave of the Witch) and the cave of Santa Lucia Inferiore, are open and equipped for the public. The caves of Toirano are well known for their beauty, for the richness of stalactites and stalagmites, but especially for the important archaeological value of the cave of Bàsura. This cave in fact preserves numerous remains of Ursus spelaeus, the cave bear, who used it as a refuge for hibernation (between about 50,000 and 24,000 years BP) and multiple evidence of the entry of prehistoric men during the Upper Palaeolithic (about 12,000 years BP).
