The Suburban Baths (Italian Terme Suburbane) are a building in Pompeii, Italy, a town in the Italian region of Campania that was buried by the eruption of Mount Vesuvius in 79 AD, which consequently preserved it. The Suburban Baths were publicly owned, as were also the Stabian, Forum, and Central baths in the city. They were built in the early empire, possibly under the Emperor Tiberius (14–37 AD), much later than the others and thus were built outside the city walls near the Porta Marina, one of the city gates. By this time, land was more easily available outside the city as the walls had lost their defensive role after the town became a Roman colony. The baths also benefitted from the increased supply of running water after the connection of the city to the Aqua Augusta aqueduct in 30–20 BC. The bathhouse was renovated after the earthquake of 62 AD, when a piscina calida, a heated swimming pool, was added to the north of the complex. The baths were discovered in 1958, much later than the rest of the city, though a systematic excavation had to wait until 1985–1987. Although publicly owned, these baths seem to have been reserved for a private clientele unlike the other public baths. The building is notable for its surviving erotic wall paintings, the only set of such art found in a public Roman bath house. Structure The building was a two-storey structure: the upper floor, as in the Palaestra/Sarno baths, was divided into three apartments for rent, with views towards the port and the Bay of Naples through the large glass windows. These rooms may also have provided space for the selling of sexual services. This upper floor was either accessed by a staircase from the floor below or via a door on the Via Marina. The baths were built to a higher standard of luxury and thermal effectiveness than the earlier baths in the town and have many hallmarks of the "newer" bath architecture of the first century AD: "single-axis row" type (with rooms in a linear increasingly warm arrangement promoting a particular route through the baths and bordering a palaestra), large windows facing southwest, and an outdoor pool with a fountain. Construction was first limited to the apodyterium (dressing room), frigidarium (cold room), tepidarium (warm room), laconicum (hot dry room) and caldarium (hot room); the natatio was added later as three
