1. 1. Ermita de la Virgen del Puerto: A Baroque Chapel for a Port Without a Sea

   Paseo de la Virgen del Puerto, 28005 Madrid, Spain

   Listen · 2:08

   Start beside the small brick chapel with the pointed slate spire, a very Madrid kind of tower that looks a little like a witch's hat, standing among the trees of the riverside promenade, with the green wall of the Casa de Campo rising beyond the water.

   This is the Ermita de la Virgen del Puerto, built in 1718 by Pedro de Ribera, the most theatrical of Madrid's baroque architects. It was commissioned by the city's corregidor, the Marqués de Vadillo, who brought with him the devotion to the Virgin of the Port, patroness of Plasencia in Extremadura. And no, there is no harbour here. The puerto in her name is a mountain pass, which suits a city that is about as far from the sea as a Spanish capital can be.

   Vadillo was a man with a plan for this neglected riverbank. Around his chapel he laid out a promenade with gardens, and he hired the same Ribera to build a grand new bridge a little further downstream. For centuries this was where Madrid came down to the river: washerwomen kneeling at the water with their bundles, families picnicking on feast days, carriages rolling along the paseo on summer evenings in search of something resembling a breeze.

   The chapel has had a hard life. In the Civil War the front line ran along this very river, and the ermita was badly damaged and had to be restored afterwards. Then, from the 1970s, the M-30 ring road was squeezed along the banks, and the little chapel spent decades listening to the roar of traffic.

   Those lanes are still here, by the way... they are just underneath you now, in tunnels. What you are walking on is a park laid over a motorway, and that is the story of this whole walk: a river that Madrid mocked, ignored and buried, and finally rediscovered. Follow the promenade south for a couple of minutes to the great granite bridge of nine arches.

2. 2. Puente de Segovia: Too Big a Bridge for Too Small a River

   Puente de Segovia, Calle de Segovia, 28005 Madrid, Spain

   Walk out onto the Puente de Segovia and lean over the granite parapet: nine sturdy arches stepping across the water, built for a river that, for most of Madrid's history, was the butt of a national joke.

   Philip II ordered this bridge, and it was designed by Juan de Herrera, the stern genius behind the monastery of El Escorial. It was finished in 1584, which makes it the oldest bridge still standing in Madrid. Philip II had moved his court to Madrid in 1561, and the new capital needed a worthy entrance from the west: this bridge carried the road towards Segovia and the mountains.

   The trouble was the river. The Manzanares is a modest stream that in a dry summer could almost be crossed without wetting your ankles, and the poets of Spain's Golden Age could not resist. Góngora wrote mocking verses about it, and a quip repeated for centuries advises Madrid to either sell the bridge or buy itself a river. Madrileños, to their credit, have been repeating the joke against themselves ever since.

   In the twentieth century the joke turned sour. The river was locked between stone walls and held back by weirs, and from the 1970s the M-30 ring road ran right along both banks. The old bridge stood stranded between lanes of traffic, and the river behind it became somewhere Madrileños drove past and never looked at.

   Then, in the mid-2000s, the city did something extraordinary. Under Mayor Alberto Ruiz-Gallardón, the motorway along this stretch was buried in tunnels, and on their roofs a new park was laid out, opened in stages and completed in 2011: Madrid Río, more than a hundred hectares of green along about six kilometres of river. Herrera's bridge was given back to the river it was built for. Cross to the far bank, the west side, and turn left to follow the long ribbon of pine trees heading south.

3. 3. Salón de Pinos: A Forest on the Roof of a Motorway

   Salón de Pinos, Madrid Río, 28011 Madrid, Spain

   Walk into the shade of the pines, a long green corridor of trunks and needles running beside the river, with joggers, cyclists and grandparents with pushchairs sharing the path.

   Now listen carefully. Somewhere under your feet, separated from you by a few metres of soil and concrete, thousands of cars are running through the tunnels of the M-30. This whole forest stands on the roof of a motorway.

   That is why it looks the way it does. The landscape architects, a team of Spanish studios working with the Dutch firm West 8, could not plant deep-rooted giants over tunnel roofs, so they chose pines and planted them in a continuous ribbon, thousands of them, arranged to feel less like a city park and more like a strip of the Sierra de Guadarrama brought down to the river. This promenade is called the Salón de Pinos, the Hall of Pines, and on a hot afternoon you understand the name.

   The project was enormous and controversial. Burying the motorway was one of the most expensive public works in the city's history, it left Madrid with a heavy debt, and for years residents lived beside giant building sites. Critics argued about the cost then, and some still do. But walk here on a Sunday and count the people who now spend their free time beside a river their parents avoided.

   The park also stitched together neighbourhoods that the motorway had kept apart for decades. On this west bank are the districts of Latina and Carabanchel, on the other side Centro and Arganzuela, and today many bridges and footbridges join them, old and new, so that crossing the Manzanares, once a matter of dodging traffic, is now a stroll. In 2015 Madrid Río received one of the best-known international prizes for urban design, awarded by Harvard. Keep following the pines south to the next bridge, the Puente de San Isidro.

4. 4. Puente de San Isidro: Goya's Meadow and a Saint Who Found Water

   Puente de San Isidro, 28005 Madrid, Spain

   Stop on the Puente de San Isidro and look west, up the gentle slope beyond the far bank, to the hill rising behind the trees. That slope is the Pradera de San Isidro, the meadow of Madrid's patron saint.

   Isidro was a real man, a farm labourer who lived around the year 1100 and worked the fields on this side of the river for a landowner of Madrid. He became the city's patron, and the legends about him are almost all about water, which tells you a lot about a dry city. The story goes that when his master was thirsty, Isidro struck the ground and a spring burst out. On the hill above the meadow stands the hermitage of San Isidro, rebuilt in the eighteenth century beside a spring whose water pilgrims still believe can heal.

   Every year on 15 May, the feast of San Isidro, the meadow fills with Madrileños in traditional dress, the men in checked caps, the women in long fringed shawls with carnations in their hair, eating rosquillas, the local doughnut-shaped pastries, and dancing the chotis on the grass.

   In 1788 Francisco de Goya sketched exactly this scene for a royal tapestry: crowds of picnickers on the meadow, with the whole skyline of Madrid floating across the river behind them, the Royal Palace and the dome of San Francisco el Grande shining in the haze. The painting is in the Prado today, and it is one of the best views of Madrid ever made... seen from where you are looking now.

   For centuries, then, this river was not a border but a front porch: the city on one bank, its holiday on the other. The motorway years broke that link, and the park has slowly mended it. Continue south along the river towards the large open space where, until a few years ago, tens of thousands of people used to sing on match days.

5. 5. Vicente Calderón Site: The Stadium Over the Motorway

   Paseo de la Virgen del Puerto 67, 28005 Madrid, Spain

   Look across the space beside the river, on the eastern bank, where new park and new buildings are taking the place of something that dominated this skyline for half a century: the Vicente Calderón, the home of Atlético de Madrid.

   The stadium opened in 1966 under the name Estadio del Manzanares, and in 1971 it was renamed after the club president who had built it, Vicente Calderón. Its most famous feature was something no architect would plan today. When the M-30 ring road was built along the river, it was run straight underneath the main stand, so that drivers passed beneath the feet of tens of thousands of fans... very few stadiums anywhere could say that.

   For Atlético supporters this was more than concrete. Here they celebrated the league and cup double of 1996, endured two seasons in the second division at the start of the 2000s, and saw the team rise again to win the league in 2014, always with the same stubborn loyalty. They are nicknamed the colchoneros, the mattress makers, because the club's red and white stripes once looked like the striped fabric of old Spanish mattresses.

   In 2017 the club moved to a new stadium on the eastern edge of the city, and the last matches were played here that spring. Demolition followed in 2019 and 2020, and many fans came to take a last photograph, or simply to stand at the gates while the stands came down. The plan for the site was the same idea as the rest of Madrid Río: cover the motorway and give the riverbank back to people.

   Old fans will tell you that on a good night the noise of the Calderón carried right across the water to Carabanchel. Now there is mostly birdsong and the clatter of building work. Walk on downstream to the baroque bridge with the two little stone pavilions in the middle.

6. 6. Puente de Toledo: Pedro de Ribera's Baroque Showpiece

   Puente de Toledo, Glorieta de las Pirámides, 28005 Madrid, Spain

   Step onto the Puente de Toledo and walk to the middle, where two little stone pavilions rise from the parapets like altars, each sheltering a saint: on one side San Isidro, on the other his wife, Santa María de la Cabeza.

   If the Puente de Segovia is a sober Renaissance statement, this is its exuberant baroque cousin. Pedro de Ribera, the same architect as the chapel at the start of the walk, designed it, and it was completed in 1732. Look at the obelisks, the scrolls, the carved niches: it is a bridge dressed for a procession. Ribera was the favourite of the city council in his day and the despair of later academic critics, who found his doorways and towers far too exuberant... which is exactly why people love them now.

   It had to be strong as well as beautiful. Earlier bridges on this spot had been carried away by the river in flood, proof that the much-mocked Manzanares could turn violent when the snow melted in the mountains. Ribera built in granite, and his bridge has survived nearly three centuries of floods, armies and traffic.

   The saints have their own story. Legend says that one day the little son of Isidro and María fell into a deep well. The parents knelt and prayed, and the water rose up the shaft until it lifted the child safely to the top. Madrileños still tell that story, and the well associated with it is shown in the city centre, in the Museo de San Isidro.

   For two centuries this was the main gateway to Madrid for travellers coming from Toledo and Andalusia, with carts, mules and coaches rattling over the stones. Today it carries only walkers and cyclists, and the traffic hums in tunnels below. On a clear day, look upstream from the middle of the bridge: the dome of San Francisco el Grande and the Royal Palace stand on their ridge above the river, the same skyline Goya painted from the meadow. Continue along the riverside path on the eastern bank. Soon you will see a strange twisted shape of steel lying across the water.

7. 7. Puente de Arganzuela and the Urban Beach

   Parque de la Arganzuela, Madrid Río, 28045 Madrid, Spain

   In front of you, two great cones of twisted steel mesh lie across the river like a pair of giant seashells, or a corkscrew built for a giant's bottle. This is the Puente de Arganzuela, one of the signature pieces of Madrid Río.

   It was designed by the French architect Dominique Perrault, the man behind the National Library of France in Paris and Madrid's own tennis arena, the Caja Mágica. Walk inside it and the steel ribbons spiral around you, the light flickering through the mesh as you climb gently over the water and down towards the parks of the south bank. It opened along with the rest of the park, at the beginning of the 2010s.

   And next to it lies something that makes visitors laugh out loud the first time they hear its name: the playa, Madrid's beach. There is no sand and no sea, of course. Instead there are shallow pools and fountains where jets and mists of water rise from the ground, and on a summer afternoon half the children of the neighbourhood are running through them.

   For a city that sits around three hundred kilometres from the nearest coast, and where August afternoons can pass forty degrees, this is serious business. Families spread towels on the grass, teenagers stage water fights, and older Madrileños sit on the benches pretending not to be envious. Madrid has always made fun of its lack of water, and here it decided to make fun with it instead.

   Look at the trees around you, too: this part of the park, the Parque de la Arganzuela, sits on land that was once rail yards, sheds and the edge of an industrial district. Further downstream, that industrial past is still standing. Follow the river south-east along the gardens to the next bridge, the Puente de Praga.

8. 8. Puente de Praga: The River Set Free

   Puente de Praga, 28045 Madrid, Spain

   From the Puente de Praga, look down at the water itself: reeds and willows on little islands of gravel, the current braiding around them, perhaps a grey heron standing perfectly still in the shallows as if it had been placed there by a landscape designer.

   It was not always like this. For most of the twentieth century the Manzanares through Madrid was a canal: straight stone walls, a flat bed, and a series of weirs that held the water back in long, still, rather murky pools. It looked tidy from a car window, and it was nearly dead.

   In 2016 the city tried an experiment. It opened the gates of the weirs and simply let the river run. Within months the water level dropped, sandbanks and gravel bars appeared, seeds carried down from the mountains took root, and plants began to grow in the middle of the channel. Fish found their way up and down the river again, and birds followed: herons, cormorants, ducks, and even the flash of a kingfisher for those with patience.

   In a few years the most mocked river in Spain became one of its most talked-about urban nature projects, studied by other cities that had once poured concrete over their own streams. Birdwatchers keep lists of the species seen along the urban river, and those lists have grown year after year. The Manzanares is still a modest river. But now it looks like a river, and that is something no one could say for a century.

   Across the bridge lies the district of Usera, home to one of the largest Chinese communities in Spain, where shop signs in Chinese characters line the streets and the Lunar New Year has become a neighbourhood festival. That is a walk for another day. For now, stay on this bank and keep going downstream to a low bridge with a curved concrete roof.

9. 9. Puente Cáscara: The Mosaic Faces Under the Shell

   Puente del Invernadero, Madrid Río, 28045 Madrid, Spain

   Walk underneath the low, curved concrete roof of this footbridge and, before you cross, tip your head back. Faces and bodies are looking down at you from the vault, life-sized figures made of thousands of tiny mosaic tiles.

   This is one of the two Puentes Cáscara, the shell bridges, twin footbridges near the Matadero whose thin concrete vaults arch over the walkway like the inside of an eggshell. Their ceilings were decorated by the Madrid artist Daniel Canogar, who is known for working with projected light and images. For these bridges he turned photographs of ordinary people into mosaic.

   The figures float, stretch and drift across the curved ceiling as if they were swimming in the river above your head, or lying on their backs in the grass on a summer afternoon. They are not saints, not kings, not footballers... they are people from Madrid, captured in poses of rest and play. In a city full of statues of the powerful, it is a rare public monument to everybody else.

   Stand in the middle and listen too. The curved shell bounces sound back, so voices, footsteps and the bells of bicycles echo strangely under the vault. Children love to shout here, and adults love to pretend they did not. Cyclists slow down without being asked, as if the low roof itself were telling them to.

   The bridges are also a quiet lesson in engineering. A thin curved shell of concrete is strong because of its shape, not its thickness, the same principle as an egg, and Spanish engineers of the twentieth century were famous for exactly this kind of daring, elegant concrete. Here the idea serves a simple purpose: shelter for a moment of crossing, a little dark room between two bright banks. Just beside the bridge, on the eastern bank, look for a long glass-and-iron hall. That is where we go next.

10. 10. Invernadero de Arganzuela: A Jungle in the Old Slaughterhouse

    Paseo de la Chopera 10, 28045 Madrid, Spain

    Stand before the long hall of iron and glass, its roof rising in a central nave like a railway station, and see through the panes not trains but palm fronds, giant leaves and the spiky silhouettes of cacti.

    This is the Invernadero de Arganzuela, also called the Palacio de Cristal de la Arganzuela, the Crystal Palace of Arganzuela. It was not built for plants at all. It was part of the old municipal slaughterhouse and cattle market next door, a working hall of the early twentieth century, all function and ventilation, through which passed the food supply of a growing capital.

    When the slaughterhouse closed, the city had a strange inheritance: a vast empty shed of glass. In 1992 it reopened as a greenhouse, and today it holds thousands of plants divided into several climate zones, from a humid tropical jungle with ponds of fish and water plants, to a dry hall of desert cactuses that look entirely at home in a Madrid August.

    It is one of those places Madrileños keep to themselves. Locals bring their children on weekend mornings, photographers come for the light filtering through the glass, and in the middle of winter it is the warmest, greenest room in the south of the city. Step inside and you change continents in a few paces: plants from tropical forests, from the Mediterranean, from the dry lands of the Americas and Africa, all under one roof. The air changes with them, from steamy and heavy to dry and dusty, so your glasses may fog up in one room and clear in the next.

    There is a lovely irony in it. A building made to serve death, the daily slaughter of the city's cattle, now exists entirely to keep things alive, and the only creatures it feeds are the fish in the ponds. Leave the greenhouse and walk a few steps further along Paseo de la Chopera to the brick pavilions of the slaughterhouse itself.

11. 11. Matadero Madrid: From Slaughterhouse to Arts Factory

    Paseo de la Chopera 14, 28045 Madrid, Spain

    Walk into the central plaza of the Matadero and turn around slowly: long pavilions of red brick trimmed with white and green-glazed tiles, a clock tower, iron gates, and people on the benches with laptops, coffees and skateboards, in a place built to process cattle.

    This was Madrid's municipal slaughterhouse and livestock market, designed by the city architect Luis Bellido and built from 1911, on what was then the southern edge of the city, beside the river and the railway. Bellido dressed a factory in neo-Mudéjar style, with brick and ceramic that echo the Islamic-influenced architecture of medieval Spain, and he arranged the pavilions like a small town, with streets between them, so that animals, workers and carts each had their own route.

    For most of the twentieth century this was a grim, noisy, essential place. Herds arrived by rail and on foot, the market traded, and meat left for the whole city every morning. The slaughterhouse finally closed in 1996, and for years the great sheds stood empty, too beautiful to demolish and too big to know what to do with.

    The answer, from the mid-2000s, was culture. The halls were converted one by one into an arts centre: Nave 16 for large exhibitions and installations, the Naves del Español theatre, and the Cineteca, a cinema devoted largely to documentary film. The building that once held the clock, the Casa del Reloj, now houses the district council of Arganzuela. There are design studios, festivals, concerts in the plaza, and on any weekend the place hums.

    And this is where the walk ends, in a fitting spot: a slaughterhouse that became an arts factory, beside a river that became a park, on top of a motorway that became a forest. Madrid spent a century turning its back on the Manzanares. Now, as you have seen, it faces it. Legazpi metro station is just outside the gates on the Plaza de Legazpi, whenever you are ready to leave.
