Ostia Antica — Rome's Harbour CityRome's Harbour City

A self-guided audio walking tour of Ostia, the harbour city at the mouth of the Tiber that grew from a fourth-century BC fort into Rome's port, with an estimated fifty thousand people in the second century AD, before trade moved to Portus. It starts among the tombs outside the Porta Romana and follows the Decumanus Maximus past the Baths of Neptune and their mosaics, the barracks of the vigiles, Agrippa's theatre and the Square of the Guilds, where the shipping offices' mosaic floors show ships, dolphins and an elephant. Then come the Four Small Temples, the House of Apuleius and the Mithraeum of the Seven Spheres, the sanctuary of Magna Mater, the great grain warehouses, a mill, the House of Diana and a thermopolium with its painted menu. The Forum follows, with the Capitolium, the Temple of Rome and Augustus, the Basilica, the Forum Baths and a twenty-seat public latrine. The walk ends in the western quarter: the builders' guild house, the Schola del Traiano, the House of Cupid and Psyche, the Baths of the Seven Sages, the Serapeum, the Porta Marina and the synagogue near the old shore.

Verified Sources

Where the facts come from

Every claim in this tour traces back to a named source — excavation records, the heritage authority for the site, and the primary texts themselves. Nothing is copied from other guidebooks, and anything we can't source doesn't make the recording.

  1. 1

    Built from the record

    Each stop is built from OpenStreetMap · 190 features in this old town (the field-surveyed mapping database behind Apple Maps), Wikidata · 69 cross-referenced entries (peer-reviewed structured records), the heritage authority below, and the primary historical texts where they exist.

  2. 2

    Checked against the authority

    Cross-referenced against Modern excavation publications · academic peer-review.

  3. 3

    Anything unsupported is cut

    Every sentence is checked against those sources before it is recorded. If a claim can't be traced, it doesn't make the audio.

  4. 4

    A person signs it off

    Every tour is reviewed by a person before it goes on sale. Stop selection, the route and anything ambiguous come back to the editor for a decision, and those questions routinely send a stop back for another accuracy pass. Nothing publishes on a machine’s say-so.

Common Questions

How it works

What does the Ostia Antica — Rome's Harbour City audio tour cover?

36 narration points, including Porta Romana, Baths of Neptune, Mithraeum of the Seven Spheres, Domus della Fortuna Annonaria and Campo della Magna Mater. That is about 62 minutes of narration in all, and you walk between the stops at your own pace.

Is the Ostia Antica — Rome's Harbour City tour self-guided?

Yes. It plays in your phone’s browser as you walk: no guide, no group, no app to install and no fixed start time.

It’s not just GPS — what are the ways to trigger a narration?

Three ways, all built in:

  • GPS-triggered (default): walk near a site, the narration starts automatically.
  • Tap any marker on the map: open the map view, tap any of the 36 markers to play that narration on demand — no walking required.
  • Queue controls: pause, skip, replay any narration; the queue auto-advances as you walk.

The map-tap option means you can stand anywhere — even at home before you travel — and play any narration. GPS just makes it hands-free while you’re actually walking the site.

Do I need cell service or data while I’m there?

No. Use the “Download for offline” button before you go, and the entire tour — audio, maps, narration text — works without any data connection. Tap-to-play and the map both work fully offline. GPS itself doesn’t need data; only the download does.

How do I make it work with no signal — and open it again later?

Add the icon first, then download from the icon. On iPhone a guide downloaded in Safari cannot be seen by the home screen icon, so downloading first means downloading the whole thing twice.

  1. Tap Download for offline above. It opens the guide.
  2. Put that page on your home screen — steps below.
  3. Open the guide from the new icon and download it there, on wi-fi. Keep the screen open until it finishes.

Putting it on your home screen — iPhone or iPad (Safari):

  1. Tap the three dots at the bottom of the screen.
  2. Tap Share.
  3. Scroll down the list and tap Add to Home Screen, then Add.

On Android (Chrome): tap the three-dot menu at the top right, tap Add to Home screen (some phones say Install app), then confirm. On Android either order works.

If you opened this link from inside Instagram, Facebook or Gmail, you are in that app’s built-in browser. It cannot add anything to your home screen, and a guide downloaded there is thrown away when the app closes. Open the link in Safari or Chrome first.

What if my phone’s GPS is unreliable?

Two backstops. First, the map shows every site — just tap the marker for the place in front of you. Second, you can manually queue any narration even when GPS is off. The platform never assumes GPS works; it’s the convenience layer, not the gate.

How long is the tour and how much time do I need?

The audio runs ~1–2 hours total, but you walk at your own pace. 36 narration points across the site. Most visitors take 2–4 hours; some spread it over multiple visits. Once you buy it, it’s yours — there’s no expiry and no subscription. Come back next year if you like; the link in your receipt always works.

Can I share with my partner or family?

One purchase covers one device session. Most couples share earbuds and use a single phone — the audio is paced for that. If you want everyone listening on their own device, each person needs their own purchase. We do not gate sharing aggressively; we trust visitors to do the right thing.

What if I never use the tour, or never make it to the site?

Full refund if you never trigger a single narration on-site. Partial refund based on how far you got. See the refund policy for specifics.
