Once the exotic playground of Roman emperors Julius Caesar, Nero and Caligula, the one-time seaside resort of Baia just north of Naples enticed and tickled the fancies of the first-century elite. Horace described it as “Nowhere in the world is more agreeable than Baia.” Pliny praised the medicinal qualities of the water.
Rich Romans built magnificent villas along the coastline that have since become submerged under water. Because the land of Baia and its surroundings are a volcanic area, the land has dropped six meters over the centuries. Today you can take a glass-bottom boat out from the harbor to view the ruins of these one-time sumptuous villas.
Desirable for its healing thermal baths, mild climate, and luxurious surroundings, Baia was conveniently situated in Campania of Southern Italy near the western corner of the Bay of Naples. The very essence of Baia inspired a spirit of idleness and pleasure among the nobility, the rich, and the famous nearly two thousand years ago. Today, the thermal bathing complex is but a faint shadow of its former magnificence.
I had the opportunity to explore the complex while staying in Napoli. My imagination was put to use as I strived to envision the ancient thermal structure at the height of its beauty. The labyrinth-like complex with its three terraces brought a distinct feeling of the immensity and grandeur of former days. Time and the shifting land due to seismic activity have ravaged it to skeletal dimensions.
A fascinating fact is that some of the most notable Roman historical events happened in Baia. To begin with, Nero had his mother Agrippina murdered here, Caligula built his famous bridge extending from Baia to Pozzuoli, Hadrian died here in 138 AD, and it is said that Cleopatra was staying in Baia when Julius Caesar died in 44 BC. Today, Baia’s archaeological park is a lifeless shell of a bygone era. The silence of the ancient city is a bit chilling.
Very little is left of the thermal establishments, promenades, terraces, and porticoed gardens. What we do know is that these public facilities provided the Romans with three kinds of baths; a frigidarium (cold water), a tepidarium (warm water) and a caldarium (hot water). Adjacent to the pools were lavishly decorated rooms for relaxation. There were also massage rooms, saunas, exercise rooms, sitting and reading rooms.
This was not just an area to bathe, but it was also used for socialization, relaxation, and meditation, as well as a place where important decisions were made. Even though wealthy Romans bathed in their own homes, they used the public baths frequently.
Below, a concrete dome with a floor of water once called the Temple of Mercury (nicknamed the Temple of Echoes for its acoustical abilities) was a bathing pool. Now the water shines inky black in hollow stillness.
The Temple of Mercury, which was not a temple but a bath, dates back to the Augustan era and is believed to be the oldest example of a large dome. Like the Pantheon in Rome, it has an oculus in the dome roof, as well as skylights. A natural spring used to flow into the room but since the seismic shifting of the land known as bradyseism, the spring is now underneath the temple water.
The Villa of the Ambulatio seen on the lower level above (must use your imagination some) was used for walks, reading, and as a retreat for its wealthy owners. While walking through the back corner, I saw bits of beautiful mosaic flooring designed in black and white. The grassy area in the forefront may have been a large pool or a garden.
Here just outside the archaeological boundaries of the thermal complex you can see the remains of the Temple of Venus. Separated by a major street, it once was part of the thermal multiplex, topped by a magnificent dome seventy feet in diameter.
Baia declined as the Roman Empire did and was invaded by the Saracens in the eighth century. It was then vacated as Malaria became a problem. What we see today is just a reminder, a monument, to the grandeur and elegance of Roman Baia at the height of its glory.
