Bagno

Bagno — 'Bath' — is a natural sulphurous thermal bathing site in Italy, likely a simple outdoor pool or natural basin fed by geothermal spring water in the terme libere tradition, whose plain Italian name reflects the fundamental and ancient human relationship with hot spring bathing that has characterised Italian culture since Roman times. The simplest Italian thermal bathing sites — just a natural pool or basin filled with volcanic or mineral spring water, often unnamed except by the most generic of descriptors — embody the democratic and elemental nature of Italy's thermal heritage. These uncelebrated but beloved bathing spots, passed down through local knowledge rather than tourism guidebooks, are among the most authentic expressions of the Italian relationship with natural geothermal water.
