Ruins of the thermae of Caracalla and of Titus are still standing.
Equally remarkable was the Roman system for supplying their city, their thermae, and their 1350 street fountains with pure water.
The public baths and thermae were under the more immediate superintendence of the aediles.

Within the town are remains of thermae on the north of the Via Appia and of a theatre opposite, on the south.
