Teatro Romano di Miseno

The Roman Theatre of Miseno lies beneath the streets of modern Miseno, once the home port of Rome's western fleet. Built in the second century AD, it occupied a narrow space between the promontory and the harbour; parts of its upper arcades are now enclosed within later buildings.

Why it matters

Misenum was more than a naval station: it was a town with a forum, baths and public entertainment. The theatre had three storeys of arched corridors built against the hillside behind the seating area. Bradyseism has lowered part of the structure close to sea level, and later construction grew over its upper levels.

What to notice

The remains include a middle corridor with cross-vaults that once supported the central tier of seats. Its brickwork shows the striped pattern known as opera vittata. Radial passages that led spectators toward the seating area are now blocked. At the thirteenth arch, a gallery once opened by ramps toward the Via Herculanea; ground movement has altered its outlook, and it now frames a view of a small cove. Part of an upper arch and stairway survives inside adjoining private property.

Context and history

The park dates the theatre's definitive burial to the beginning of the fifth century, with occupation in the surrounding area continuing until no later than the seventh. Excavations in a state-owned strip in 2003 revealed structures of a public area connected with the theatre and probably the nearby forum. The building's present form reflects the combined effects of ground movement, burial and later urban development.
