Ancient Rome's Port City

Ostia Antica is one of Italy's most remarkable archaeological sites: an entire Roman city, preserved intact, just 30 minutes from Rome. It served as the capital's river and sea port (the name comes from ostium, "mouth" — the mouth of the Tiber), the place where grain arrived and the wealth of the empire set sail. When the harbour silted up and the city was abandoned, the sand sealed it for centuries, giving us an extraordinary state of preservation.

Often called the "Pompeii near Rome," Ostia Antica has one big advantage: it's incredibly easy to reach and far less crowded. Strolling down the Decumano Massimo, stepping into the houses, climbing the tiers of the theatre — it feels like a direct leap into the daily life of ancient Rome.

Why Visit

  • Exceptional preservation: streets, multi-storey apartment blocks (insulae), baths, shops and mosaics all intact.
  • Right next to Rome: 30 minutes by train or car, perfect for a half-day trip.
  • Uncrowded: a calm experience, away from the crowds of the city centre.
  • For everyone: wide open-air spaces, ideal for families and history lovers alike.

  • The Square of the Guilds, with the mosaics of the ancient trading offices.
  • The Baths of Neptune, with their stunning mosaics.
  • The Thermopolium, the ancient Roman "bar."
