Altinum

Listen first. Out here, on the flat green edge of the Venetian lagoon, the loudest sound is often the wind in the reeds. Fields stretch toward a low horizon. A heron lifts out of a ditch. The air smells of wet earth and salt. Nothing here looks like a city. And yet, under the grass at your feet, there was once a busy Roman town, one of the most important on this whole stretch of coast. Its name was Altinum.

Today the place sits beside the small village of Quarto d'Altino, on the mainland just north of the lagoon. Venice itself lies across the water to the south. On a clear day you can sometimes make out bell towers on the islands. That view matters, because the story of Altinum and the story of Venice are tied together. Many historians see this town as one of the places where Venice began... before Venice existed at all.

Long before the Romans, this land belonged to a people called the Veneti. They were an ancient Italic people of the northeast, and the region still carries their name. The Veneti lived along the rivers and the lagoon edge. They were known across the ancient world for their horses. Archaeologists working around Altino have found Venetic burials, and among them are burials of horses. That detail tells you how much these animals meant to the people who lived here.

When Rome expanded north, the Veneti became allies, and later citizens. Altinum grew into a Roman town with streets, temples, houses and a harbour. Its position was its fortune. It stood where land routes met the lagoon and the sea. Ships could reach it through the shallow channels. Goods moved inland by road and by river. Wool, wine, fish and pottery all passed through here. For centuries this was a place of traders, sailors and merchants.

Two great Roman roads connected the town to the wider empire. The Via Annia ran along the coast, linking this area with other cities of the northeast. The Via Claudia Augusta began here and climbed north, over the Alps, toward the lands along the Danube. Think about that for a moment. A traveller could leave this quiet field and walk, step by step, all the way into central Europe. Altinum was a doorway between the Mediterranean and the north.

Here is a detail most visitors miss. In the second century, the Roman emperor Lucius Verus, who shared the throne with Marcus Aurelius, fell ill on the road near Altinum. He died there, in the year 169. An emperor of Rome ended his life in this flat country between the fields and the lagoon. It is a reminder of how central this place once was. Important people did not pass through unimportant towns.

So what happened? Why is there grass here, and not a city? The decline was slow. In late antiquity the empire weakened, and invading armies crossed northern Italy. Attila and the Huns swept through the region in the fifth century, and the town is often linked with that invasion. The rivers also changed course over time, and the land became harder to live on. Bit by bit, people moved away from the mainland.

Where did they go? Many went out into the lagoon, to the islands. There, among the marshes and channels, invaders on horseback could not easily follow. Tradition holds that people from Altinum settled on the island of Torcello. Legend adds a lovely touch: some say the new island communities took the names of the old city gates with them. Whether that story is true or not, the move itself is well accepted. The bishop of Altinum later moved to Torcello, and the town's religious life went with him.

The settlers did not leave empty-handed. They carried stone. Roman columns, carved blocks and inscriptions were taken from the ruins and used again in the new churches and houses of the lagoon. If you visit Torcello or walk through Venice, you may be looking at pieces of this Roman town without knowing it. In a very real sense, parts of Altinum still stand... just not here. Venice was built, in part, from what this town left behind.

Now for the second surprise. For a long time, nobody could see the full shape of the buried city. Then, during a very dry summer, the soil dried unevenly over the ancient walls and streets. Crops grew differently above buried stone. Researchers studied aerial photographs and found the outline of the whole town drawn in the fields: streets, a theatre, walls, canals and the harbour area. A city appeared from the air, though it had been invisible from the ground.

On site today, the remains are modest but real. In the archaeological area you can see sections of Roman road, with large paving stones worn smooth. You can see low foundations of buildings and the base of a city gate. These stones do not rise high. You need to look closely and use your imagination. Picture carts rolling over this paving, merchants calling out prices, and boats unloading at the water's edge just beyond.

The National Archaeological Museum of Altino helps fill in the picture. Inside, you will find objects that came out of this ground: mosaic floors, funerary monuments, portrait heads, glass, coins and everyday pottery. The grave markers are especially moving. They carry the names of ordinary people, families who lived and died here. Take your time with them. They are the closest you will come to hearing the voices of the town's residents.

Before you leave, stand still for a moment and look south, toward the lagoon. The same water that once carried ships into this harbour later carried families away to safety. Feel the wind again, and listen to the reeds. When you return to Venice, with its crowded canals and marble palaces, remember this quiet field. Remember that some of that city's first stones, and some of its first people, came from right here.
