 Camerano is most notable for the extensive tunnel system that lies underneath most of the old city.These tunnels were constructed in the sandstone bedrock of Camera, with constructions happening piecemeal from the Roman era, up until the 1800s.Although the cause for this tunnel building was originally thought to have been as wine storage cellars, later exploration has revealed that these tunnels began with the Romans, and then were greatly enlarged to function as a refuge from the Moorish incursions into Italy during the early medieval period.
