The excavation aimed to study the chronology, architectural layout, and water supply system of the baths complex close to the forum. In particular, the project analysed the simultaneous development of the bath structures both on the surface and below ground, a configuration that makes the complex rather unique. Primarily seen as a supplement to the fieldwork that led to the Cosa III volume, this new campaign examined a building and its socio-cultural context, discussing the general settlement narrative traced by previous studies.
