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, sand and sediment buried it for centuries, sealing the streets, houses, baths and mosaics and giving us an extraordinary state of preservation.
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.
What to See
The Decumano Massimo
The city's backbone is the Decumano Massimo, the long paved main street that runs through the entire site. Following it, you pass baths, shops, warehouses and houses: it's the perfect thread to find your way and picture daily life in the port of Rome.
The Roman Theatre
The Square of the Guilds
Right behind the theatre, the Square of the Guilds is one of the most fascinating places in Ostia: a vast porticoed space that once housed the offices of merchant and shipowner guilds. On the ground, stunning mosaics depict ships, animals and trade symbols, marking the business of each office — a unique record of commerce in ancient Rome.
The Baths of Neptune
Among the bath complexes, the Baths of Neptune stand out, famous for their large black-and-white floor mosaics depicting Neptune on a chariot drawn by sea horses, surrounded by marine creatures. From a terrace you can admire them from above in their full extent.
The Thermopolium
To understand everyday life, don't miss the Thermopolium: the ancient Roman "bar" or snack counter, with its marble counter, frescoes illustrating the food on sale, and the rooms where customers ate. It's one of the most vivid and "human" glimpses in all of Ostia.
The houses, the mosaics and the Capitolium
Rounding out the visit:
- The insulae, the multi-storey working-class apartment blocks, ancestors of the modern condominium.
- The domus, the private homes, with their mosaics and frescoes.
- The Capitolium and the Forum, the religious and civic heart of the city.
- The Museo Ostiense (Ostia Antica Museum), with the sculptures and finds unearthed during the excavations.
Tickets and Opening Hours
Tickets: how much it costs
Entry to the Parco Archeologico di Ostia Antica requires a modestly priced ticket (approximate — check current prices on the official website), with a reduced rate for EU visitors aged 18 to 25 and free entry for under-18s. The ticket grants access to the entire archaeological park — streets, houses, baths, theatre, mosaics — and, as a rule, to the Museo Ostiense, home to sculptures and finds unearthed during the excavations. Prices may change during exhibitions or special events, and some areas may have restricted access or require advance booking.
| Visitor | Ticket |
|---|---|
| Full price | Modest standard fee (check official website) |
| EU citizens aged 18–25 | Reduced rate |
| Under 18 | Free |
| First Sunday of the month | Free (national initiative) |
Opening hours
Ostia Antica is generally open Tuesday to Sunday, with hours that shift by season: it closes later in summer, earlier in winter (approximate — check the official website). Last admission is usually about one hour to ninety minutes before closing.
| Open | Tuesday to Sunday |
|---|---|
| Closed | Mondays |
| Hours | Seasonal — later in summer, earlier in winter |
| Last admission | About 60–90 minutes before closing |
Because the site is so vast, plan to arrive in the morning so you have plenty of time to explore at your own pace.
Free entry
Admission is free on the first Sunday of the month (a national initiative for state-run museums) and on a handful of special days. It's the best deal, but also the busiest: arrive at opening to enjoy the park in peace.
How to Get There
The Parco Archeologico di Ostia Antica sits about 30 km from central Rome, toward the sea and just a few kilometers from Fiumicino airport. The distance may suggest a far-off day trip, but it's actually quick and easy to reach, whether by public transport or by car.
By train (Metromare)
The cheapest way is the train:
- From Porta San Paolo station, next to the Piramide (Line B) metro stop, the Metromare line (formerly Roma-Lido) departs.
- Get off at the Ostia Antica stop, from which the park is a few minutes on foot across an overpass.
- The ride takes about 30–40 minutes, on a standard integrated city ticket.
It's a handy option, but the train can get crowded and timetables are worth checking.
By car
By car from central Rome you arrive in about 30 minutes along the Via del Mare / Via Ostiense. Parking is available near the park entrance. It's convenient, but factor in rush-hour traffic and summer weekends, when crowds head for the coast.
With a private driver (NCC)
For maximum comfort, a private driver (NCC) is the ideal choice: door to door from your hotel to the park entrance in about 30 minutes, with no train, no connections and no parking to worry about. It's especially convenient for families, groups, anyone short on time, or travelers who want to pair Ostia Antica with a transfer to or from Fiumicino airport, which is right nearby. A little-known advantage: with a private driver you can visit on your last day before your flight, leaving your luggage in the car and heading straight to the airport afterward — a smart way to make the most of your time.

Practical Tips
Ostia Antica is large: a complete visit takes at least 3 hours, ideally half a day. To catch the best of it, follow this order along the Decumano:
- Necropolis and entrance (Porta Romana)
- Baths of Neptune
- Roman Theatre and Square of the Guilds
- Thermopolium and the houses
- Forum and Capitolium
- Museo Ostiense (Ostia Antica Museum)
A few more pointers:
- Buy online to skip the ticket-office queue, especially on the first Sunday of the month.
- Avoid Monday: it's the closing day.
- Go in the morning: the site is huge and needs at least 3 hours.
- Comfortable shoes, water and a hat: there's a lot of walking and very little shade.
The site pairs easily with a stop on the coast or a same-day return to Rome.
Ostia Antica or Pompeii?
Many people wonder whether to choose Ostia Antica or Pompeii. The answer comes down to time: Ostia is 30 minutes away and can be seen in half a day; Pompeii means a full-day trip toward Naples. The two are complementary — Ostia is closer, less crowded and ideal for half a day; Pompeii is bigger and more famous but requires far more travel. We cover this in our guide Ostia Antica or Pompeii.
