There were three main bath chambers: the frigidarium, or cold room; the caldarium, or hot room; and the tepidarium, or lukewarm room. Between the frigidarium and the tepidarium was the great hall, roofed by an enormous vault with clerestory windows, a prototype of the vaulted naves of medieval churches.

The Appian Way was celebrated by Horace and Statius, who called it longarum regina viarum, or “queen of long-distance roads.” As the main highway to the seaports of southeastern Italy, and thus to Greece and the eastern Mediterranean, the Appian Way was so important that during the empire it was administered by a curator of praetorian rank. The road averaged 20 feet (6 metres) in width and was slightly convex in surface in order to facilitate the drainage. The road’s foundation was of heavy stone blocks cemented together with lime mortar; over these were laid polygonal blocks of lava that were smoothly and expertly fitted together. The first few miles of the Appian Way are flanked by a striking series of monuments, and there are also milestones and other inscriptions along the remains of the road.
