Vía de la Plata

Listen to the ground for a moment. Under the dust and the tufts of grass, there may be a line of old stones — worn smooth, set close together, running straight ahead. Around you, holm oaks stand apart from one another on rolling pasture. Cattle move slowly in the shade. The air smells of dry earth and warm bark. You are standing on one of the oldest routes in Spain, a road that has carried soldiers, merchants, shepherds and pilgrims for close to two thousand years.

This is the Vía de la Plata. In English, the name sounds like "the Silver Way". It is easy to imagine carts full of silver bars rolling north. But most historians think the name has a plainer origin. Many trace it to an Arabic word, balat, which can mean a paved road. So the "silver" may simply be a later mishearing of "the paved way". Either way, the name stuck — and the road kept its importance long after Rome had gone.

The Romans built this road to link two cities in the west of their Iberian provinces. In the south was Emerita Augusta, today's Mérida. In the north was Asturica Augusta, today's Astorga, close to the gold mines of the northwest. The road ran across the whole western side of the peninsula. It moved troops, tax collectors and officials. It also moved ideas, coins and goods. The Province of Salamanca sits roughly in the middle of this long line.

Here is a detail many visitors walk straight past. The Romans marked distance with milestones. These were tall stone columns, usually cylindrical, set beside the road at every Roman mile. A Roman mile was about one and a half kilometres. Many of the stones carried carved inscriptions naming the emperor who built or repaired that stretch. Salamanca's southern section still holds a remarkable number of these columns. Some stand where they were found. Others lean in village squares or rest against farm walls.

The area around Calzada de Béjar is one of the best places to see them. Even the village name carries the road inside it. In Spanish, "calzada" means a paved road or causeway — the same word used for the Roman route itself. Here, a stretch of the old road crosses open country, and the milestones appear one after another. Walking it, you can feel the rhythm the Romans built into the landscape: a steady line, a measured pace, a stone at every mile.

Notice how the road behaves. Roman engineers liked straight lines and gentle slopes. Where possible, they avoided steep climbs and soft valley floors. They raised the road on a bank of packed earth and gravel, with larger stones at the edges. Over the centuries, much of the top surface has gone. Farmers reused the stones for walls and houses. Yet the line of the road often survives — as a raised track, a field boundary, or a path that runs straight while everything around it curves.

The landscape itself is part of the story. This is dehesa, a type of open woodland pasture typical of western Spain. People have shaped it over many centuries. They thinned the oak forest, kept the best trees, and let animals graze beneath them. Acorns feed the pigs in autumn. Cattle and sheep use the grass. The granite outcrops break through the soil in rounded grey shapes. It looks wild, but it is a working landscape, and a very old one.

After Rome, the road did not disappear. It became a route for the movement of livestock between summer and winter pastures, a practice called transhumance. Shepherds walked huge flocks along old tracks like this one, season after season. Medieval armies used it too, during the long centuries of conflict between Christian and Muslim kingdoms. The road connected towns, markets and castles. Its stones carried every kind of traffic that a frontier land could produce.

Today, most people on this road are pilgrims. The Vía de la Plata is one of the routes of the Camino de Santiago, the pilgrimage to the tomb of Saint James in Santiago de Compostela. Many walkers start in Seville, far to the south. They follow yellow arrows painted on rocks, posts and walls. They carry scallop shells, the old symbol of the pilgrimage. If you see someone with a heavy pack and dusty boots, there is a good chance they have already walked for weeks.

In villages such as Fuenterroble de Salvatierra, pilgrim hostels have become small centres of life. Walkers arrive in the afternoon, wash their socks, and share food at long tables. The church bell marks the hours. Conversations happen in five or six languages at once. For a village with a small population, this steady flow of strangers is part of daily routine. It is a modern echo of an old function: the road still brings people from far away to the doors of these houses.

Further north, the road reaches the city of Salamanca, known to the Romans as Salmantica. It crosses the river Tormes on the Roman bridge. Part of the bridge goes back to Roman times, while other arches were rebuilt in later centuries after floods. And here is a second surprise. Near the bridge stands a worn stone animal — a verraco, a bull or boar carved by Iron Age peoples long before the Romans arrived. It appears in a famous sixteenth century Spanish novel, "Lazarillo de Tormes".

In that story, a young boy works as a guide for a blind man. Near the bridge, the blind man tells the boy to put his ear to the stone animal and listen. When the boy does, the man smashes his head against the stone. It is a cruel lesson: a guide must stay sharp. So, in a way, this old road already holds a warning for anyone who leads travellers. Keep your eyes open. Pay attention to the stones under your feet.

Think about the layers you are walking through. Iron Age peoples carved animals from granite. The Romans laid a measured road across their lands. Shepherds, soldiers and traders followed. Writers turned the bridge into a scene of literature. Now walkers with phones and walking poles follow painted arrows north. None of these layers erased the one before. They sit on top of each other, like the gravel, earth and stone that form the road itself.

Before you move on, look once more along the line of the road. Find the next stone, the next arrow, or the next gap between the oaks. Listen to the wind in the leaves and the bells of the cattle. When you walk away, notice how straight your path runs, and how the fields seem to bend around it. That straight line is the Romans, still here — quietly guiding every step you take.
