Excavations on this site first began during the 1970s. A carpark was added much later, constructed to suspend over the ruins of the 1st-century CE baths.
Visitors can view the ruins from two streets and the site can be visited on a series of elevated walkways. These allow guests to see the remains in their full glory and the excavation work taking place. Two small showrooms with explanatory panels preserve a selection of artifacts discovered during excavations from 2006-2008.
The baths are believed to have been the largest outside of Rome, covering an area of about 1,500 square meters. It was constructed with donations from Pliny the Younger, a politician from Como who held various positions throughout the empire.
The site was extended during the 2nd-century, but by the end of the 3rd-century, the baths were dismantled with the floors, decorations, and infrastructure removed. Other building materials were also dismantled. The site was later used as a necropolis.
