The slightly forgotten historical site of Ostia Antica, is definitely worth a visit. It is an extraordinary site that contains the ruins of the ancient port town that served as the gateway to Rome.
One can trace its roots back the the 4th century B.C. This town is a witness and a monument to the rise of the roman empire. In this very well preserved historical site, one can view the theatre, military camps, baths and even Europe’s oldest known Synagogue. Ostia Antica is best known for being under attack from pirates in 68 B.C. giving more power to Pompey the great, who damaged the foundations of the Republican system.
Walking through these ruins, you will feel as inspired as if you were walking through Pompey, however, with the benefit of less tourists.
