Absolutely worth a visit the archeological area of Ostia, 15 miles from the center,dated fourth century B.C. and once the port of Rome. Review the history through the theaters, the temples, the public and private buildings. See the Thermopolium, were the romans had a sneak lunch and a drink; the Spa places for the baths in pools and steam baths, a real cult by the Romans. The forum, the Horrea deposits for the goods, the sanctuaries of the god Mithra, an oriental cult particularly venerated here, as well as the Square of the Corporations featuring the representation offices of the traders; the Forica the public toilets incredibly the place of meetings and conversations, as written by the Latin poet Giovenale.
