Two circles, one ring-shaped and open, the other full, appear along state highway 68, on the stretch that connects Volterra to the Saline hamlet. Both of these signs, typical of Staccioli, run along the road on the hill, underlining one of the most trodden streets outside Volterra. In the underground at the foot of the town hill, the inhabitants used to extract, with a rather bizarre technique, the so-called “white gold” from the salt-mines. Today, despite its slow decline, this road which, ever since ancient times, has served as an enormous, resourceful mine, still marks the lot of these places.
