11) Roman Theatre of Misenum

11. Roman Theater of Misenum

Still partially buried beneath modern buildings, the access corridors (vomitoria) are visible. It could accommodate thousands of spectators, testifying to the importance of the Misenum naval base.

The Roman Theater of Misenum is one of the most evocative and, at the same time, emblematic monuments of the historical stratification of the Phlegraean Fields. Located on the northern slope of the Misenum promontory, the building exploited the natural slope of the hill to support its steps (the cavea), a technique typical of Greek theater architecture later perfected by the Romans. Although today largely incorporated by modern construction and partially buried, what remains visible is sufficient to testify to the grandeur of this structure, which could accommodate approximately 2,000 spectators.

Originally, the theater was decorated with precious marbles and statues, serving as a cultural center for veterans and sailors of the Classis Misenensis. One of the most fascinating features is the system of internal galleries, known as vomitoria, which allowed for the rapid outflow of the audience. Some of these corridors are still accessible and demonstrate an extremely precise opus reticulatum construction technique. The theater's location was no accident: from the highest tiers, audiences could enjoy a breathtaking view of the inner harbor (the Maremorto) and the warships at anchor. Imagining this space alive today, with theatrical performances and official celebrations, helps us understand how Misenum was not just a rigid military base, but a fully-fledged Roman city, vibrant with social life and intellectual entertainment.
