The Maritime Theater includes a lounge, a library, heated baths, three suites with heated floors, washbasin, an art gallery, and a large fountain.[2] During the ancient times, the island was connected to the portico by two wooden drawbridges. On the island sits a small domus, complete with an atrium, a library, a triclinium, and small baths. The area was probably used by the emperor as a retreat from the busy life at the court.
