Beneath the Renaissance palace lie eleventh-century baths. Follow the rooms and their small light openings, imagining how architecture, water and heat shaped bathing. This is a heritage visit, not a working spa. The building above adds collections and cultural activities. Decide what to see and check current access arrangements before planning your visit.

Plan this visit
Follow the architecture of temperature
The official description distinguishes cold, warm and hot rooms and explains heat circulating below the floor. We suggest comparing shape, size and light openings to understand how space served bathing. This is not about imagining modern swimming pools or expecting an operating thermal spa.
Two layers within one visit
Relate the baths to the palace built above them: changing level also expresses changing use. Then decide whether to extend the stop to the cultural centre’s collections, checking current access. Exploring every area takes longer than visiting the bathing rooms alone; allow time rather than treating nearby galleries as automatically included in a short visit. The palace collections offer a different observation theme.
