Ponte Vella
Roman-founded bridge over the Miño in Ourense, rebuilt in the Middle Ages and now pedestrian only, with the city thermal pools downstream

Overview
Ponte Vella is the long granite bridge that carries walkers over the Miño in Ourense, Roman in origin and medieval in almost everything you can now see. It runs 370 metres across the river, its central arch spanning 43 metres and rising about 38 metres above the water.
Seven of an original eleven arches survive, and the pointed ones give away the thirteenth-century rebuild rather than the Roman crossing underneath. Ourense treats it as one of the three things that stand for the city, alongside the As Burgas springs and the cathedral of San Martiño. Expect to see it labelled three different ways on maps and signs: Ponte Vella is the everyday name, Ponte Maior the formal one, and Ponte Romana the one that oversells what is actually visible.
That civic status is literal as well as sentimental: the bridge is drawn on the city’s coat of arms, complete with a defensive tower that no longer exists. The tower came down in the middle of the nineteenth century when the Villacastín to Vigo road was pushed through, so the heraldry now records a version of the bridge that no visitor has seen for well over a century.
Walking it costs nothing and there is no gate, ticket desk or attendant at either end. Cars were removed at the end of the twentieth century once other crossings took the traffic, and the deck now belongs to commuters, dog walkers and pilgrims heading north.
The other reason to be here is the water. Ourense sits on springs that push out more than three million litres of thermal water a day, and the pools strung along the Miño downstream are the city’s second attraction after the bridge itself. Cross the bridge, look downstream, and you are looking at the start of that walk.
History
The first crossing here went up in the first century AD, on a branch of the Roman road catalogued as Via XVIII in the Antonine Itinerary and better known as the Vía Nova, the route linking Bracara Augusta with Lucus Augusti. That put the bridge at a junction in the middle of the province of Gallaecia, which is most of the reason a town grew around it.
The usual claim that it was built under Augustus rests on typological similarities with the Roman bridge at Mérida, and nothing firmer: there is no historical, epigraphic or archaeological evidence that pins the date. What there is, is structural. Borings taken through the fabric in the 1960s found vertical facings of an older bridge embedded inside the present one, and those are reckoned to be the Roman work. So the Roman bridge is genuinely still there, just entirely swallowed. You cannot see a single course of it from the deck.
The crossing was not the only draw. Roman settlement here grew around the As Burgas springs, where bathhouses and sanctuaries were built on waters that had been venerated before the Romans arrived, and the town still sits on springs discharging more than three million litres a day. A bridge, a road junction and hot water is a durable combination, and it is why a river crossing in the middle of Gallaecia turned into a city rather than a way station.
Four centuries of collapse and repair
The main arch gave way during the twelfth century, and that failure set off a cycle of repairs and further collapses that ran on for roughly five hundred years. The major campaign of renewal falls between 1230 and 1449, and the pointed arches you walk over are its signature.
The last serious reconstruction came in the seventeenth century, around 1660, under Melchor de Velasco Agüero. That is the bridge you cross: unambiguously medieval in appearance, with no Roman masonry left in view, and reinforced again in the same century.
Four of the eleven original arches were lost along the way, leaving the seven that stand. The result is a bridge with a very odd profile for a Roman one: it climbs steeply to a single enormous central arch instead of running level on a repeating rhythm of similar spans. That 43 metre opening was the widest stone arch in Spain for a very long stretch of the country’s building history, and it is the seventeenth-century solution to a problem the twelfth century created.
Tower, monument status and the end of traffic
The bridge carried a tower until the middle of the nineteenth century, when the new Villacastín to Vigo road went in and the tower was demolished. Protection arrived much later. A state decree of 6 April 1961, published in the Boletín Oficial del Estado on 18 April, declared as a historic-artistic monument not the bridge alone but the ensemble it forms with the chapel of Nuestra Señora de los Remedios beside it. It is therefore a Bien de Interés Cultural with the category of Monumento.
Vehicles kept crossing until the pedestrianisation at the end of the twentieth century, which is when the bridge stopped being infrastructure and became an emblem. Its Camino role survived that change intact: the crossing is on the Vía de la Plata route towards Santiago de Compostela, and pilgrims still use it as the way into the old town.
Visiting
Access is free and permanent. There are no gates, no ticket desk and nobody on duty, and the Ourense tourism board simply lists the bridge as open to visit with no hours attached. Twenty minutes covers a crossing with photographs at both ends; five minutes covers it if you are only getting from one bank to the other.
The deck is not flat. It climbs continuously from both banks to the crown over the central arch, which puts you roughly 38 metres above the Miño at the midpoint. That is the spot worth stopping at, with the old town and the cathedral behind you on one side and the river bending away downstream on the other.
The bridge is about five metres wide, which is generous by medieval standards and explains why it coped with wheeled traffic for so long. Look down at the parapet line as you climb and you can read the repair history off the stonework: the pointed arches belong to the medieval rebuilding, the great central span to the seventeenth century, and the semicircular refuges set over the pier buttresses are where foot traffic once got out of the way of carts.
The municipal tourism listing rates the bridge as “practicable” for reduced mobility, meaning you can get onto it and cross it, without promising a level surface. Treat that honestly: the gradient is real, the granite is slick in the rain, and there is no shade or shelter anywhere on the span.
The best views of the bridge are not from it. Ourense has six crossings over the Miño, and the one that gets photographed alongside Ponte Vella is the Ponte do Milenio, a steel and concrete span opened on 1 September 2001 whose pedestrian walkway loops up about 22 metres above the deck. It sits downstream of the old bridge, so the climb gives you the medieval arches in profile with the city behind them.
That same bridge is where the thermal walk begins: four kilometres of green riverside path linking eight thermal spaces along the Miño. A longer riverbank route of somewhat more than twelve kilometres continues beyond it.
Going downstream, the sequence runs A Chavasqueira, then the paid spa of the same name, the O Tinteiro spring, the four pools at Muíño da Veiga, the paid Termas de Outariz, the free pools at Outariz, Burga de Canedo, and the Fonte de Reza. A Chavasqueira is the bathing area closest to the city centre, an open-air set of natural pools with free access; Outariz, Burga de Canedo and Muíño da Veiga are also free. The paid options are Termas de Outariz, Termas A Chavasqueira, and the outdoor thermal pool at As Burgas in the centre.
A thermal train runs out to the pools for anyone who does not fancy the return leg on foot.
Pair the two and you have the standard Ourense half-day: cross the old bridge on the Camino line into the old town, walk down the riverbank, get in the water, and ride or walk back.
Tips
-
Free and open at all hours, with no staff, no signage panel and nothing to book. Nobody will stop you crossing at two in the morning, and the granite is lit.
-
Photograph the bridge from the Ponte do Milenio, not from the bridge itself. Its raised walkway gets you about 22 metres up and gives the profile shot of the medieval arches.
-
Bring swimwear if you are crossing in the afternoon. The free pools at A Chavasqueira are the closest thermal bathing to the centre, and cost nothing.
If you want a roof and a changing room rather than an open riverbank, the paid spa at A Chavasqueira reopened on 7 October 2025, and Termas de Outariz operates further downstream. Both sit on the same four kilometre riverside path, so you can walk out along the pools and pick whichever suits the weather.
-
Do not expect to see Roman stonework. The visible fabric is medieval and seventeenth century; the Roman facings are buried inside the piers and were only confirmed by borings in the 1960s.
-
The chapel of Nuestra Señora de los Remedios is part of the same protected monument, so it is worth the two minutes it takes to look at it while you are at the bridge.
-
Come early or after dark if you want the span to yourself. It is a working commuter route as well as a monument, and it is also a Camino crossing on the Vía de la Plata, so spring and autumn mornings bring pilgrims.
-
Read the arches from the riverbank rather than the deck. From below you can see how uneven the seven surviving spans are, which is the clearest evidence that this is four separate bridges stacked on one alignment.
-
Pack a rain jacket rather than an umbrella. Ourense weather turns fast and the crown of the bridge is exposed on both sides.
