One of the immediate charms of Madrid is how relatively compact its historic center is. A visitor can easily walk from the Retiro Park, to the Prado, to Gran Vía, and to the Templo de Debod in the course of a day. Exploring this way, Madrid is experienced as a series of unfolding streets, plazas, and monuments, winding and criss-crossing their way across a relatively flat landscape. And yet, to get an idea of the contours of the land, of the natural environment that the city inhabits, one must venture further—to the Madrid Río.
This is a park that runs along the Manzanares River. “River” is a generous term for this trickle of water. Originating in the high sierra, the Manzanares runs southward, eventually emptying into the mightier Jarama to the south. As a natural resource, it is almost negligible—far too shallow for boat travel, and far too scanty to be a significant source of drinking water. But it is this slight river, working over the course of centuries, which carved out the high bluff upon which the Royal Palace is now situated, and which formed the core of the original settlement of Madrid. In other words, it is because of the small valley created by the Manzanares that anyone thought of settling here in the first place.

And the Manzanares has never lost its importance. It makes an appearance in many of Goya’s paintings, as a kind of pleasure ground, where aristocrats dressed as majos and majas took their leisure. During the Spanish Civil War, this humble river formed an important line of defense for the city. And during this century, the Madrid Río was the site of a major project of urban renewal.

For years, you see, this trickle of water had been sandwiched between the two directions of the M-30, the circular highway that was built in the 1960s to alleviate congestion in the city center. With three lanes of traffic on either side, the Manzanares could no longer be enjoyed by the madrileños.
Yet this changed in the early 2000s, when control of the highway was passed to the local city government, who soon decided to move this section of the highway underground. As you might imagine, this was a massive project, costing several billion euros; and it resulted in the longest network of traffic tunnels in Europe.
But it was worth it—for the burial of the highway solved many urban problems at once. Most obviously, it helped to alleviate some of the noise and pollution of the passing traffic. What’s more, the project re-connected neighborhoods that had been cut in two by the highway, weaving the city together again.
But the most precious result of this project was, I think, the restored access to the Manzanares River. This is no small matter. In a city lacking in any conspicuous natural features, the humble Manzanares is one of the only things that ties the city center to the landscape. And the good citizens not only got their river back, but a wonderful park to boot. Stretching for miles on either side of the river, the Madrid Río Park was created on the surface of the highway tunnels—and it is now one of the treasures of the city.

For the most part, this park consists of walking, jogging, and biking paths that run parallel to the course of the river. Shade is, admittedly, something of a problem in the hotter months, as the recently-planted trees haven’t had time to grow to their full splendor yet. Still, for such a narrow park, surrounded on both sides by apartment buildings, it can feel remarkably peaceful and quiet. Traffic passes over and under, largely out of view.

The park is notable for the many attractive pedestrian bridges that connect its two sides. There are the two “shell bridges,” near the Matadero, with lovely paintings on the inside. The aptly-named Puente monumental de Arganzuela is an enormous spiral that swirls across the river. A favorite of mine is the Puente del Principado de Andorra, which is a kind of faux-railway bridge, made with crisscrossing iron beams, but which splits apart to form a triangle.

The most beautiful, by far, is the Puente de Toledo—a stone bridge built in an ornate Barroque style. It emulates the far older, and more historically significant, Puente de Segovia. Built in the 16th century, this was the first major bridge to span the Manzanares river. It was mentioned frequently by Spain’s Golden-Age poets—though, admittedly, often in a humorous vein, for being so enormous in comparison with the stream it spans. It is a bridge in search of a river, mucho puente para tan poco río.

I want to mention here something puzzling to many visitors. At several points along the river there are what appear to be Greek columns. They look old and weather-beaten, and at first I wondered if they were genuine remains of an old temple. But their placement—much too far apart to belong to a single building—seemed to eliminate that possibility. The truth is that these are not columns at all, but ventilation shafts. You can prove this for yourself if you observe them from above: they are hollow inside.
You see, one of the reasons it was originally decided to canalize the river was that it was becoming a hazard for hygiene. As sewage continually drained into the Manzanares, it became an open cesspool. Thus, underground channels were made to divert contaminated groundwater. These channels had to be ventilated, to prevent pressure from building up, and the air shafts were disguised as Greek columns. If you look closely, you will notice that some of them still bear the scars from bullets and shrapnel from the Spanish Civil War.

Apart from its bridges, the river is also crossed by several dams—seven, to be exact. In the past, these were used to build up the waters of the Manzanares to a respectable level, allowing the citizens to swim and even the local rowing teams to practice. Yet this was not good for the wildlife—trapping fish, and flooding the many habitats adjacent to the river.
A major decision in the creation of the Madrid Río park was the opening of the dams, allowing the river to return to its natural state. This rewilding has created a surprisingly vibrant ecosystem in the sandy banks of the river, where plants and animals thrive. Especially happy are the birds, which have flocked to the area. Now, a visitor can see an astounding variety of species, from nile geese to herons to cormorants. (The rowing team, on the other hand, have been left up the river without a paddle.)

The Madrid Río is also home to some cultural sights. The Ermita de la Vírgen del Puerto (Hermitage of the Virgin of the Harbor) is a rather severe brick building from the early 18th century, where madrileños like to practice salsa dancing. Nearby is the Ermita de San Antonio de la Florida, a church decorated by Francisco de Goya, which also serves as the painter’s tomb. (Across the street is Casa Mingo, a classic restaurant serving roast chicken.) Further down is the Puente de los Franceses, a railroad bridge built by French engineers, which served as an important point in the defense of Madrid by the International Brigades during the Civil War.
Yet the most significant cultural landmark along the river may be the Matadero. The word matadero is simply Spanish for “slaughterhouse,” and that is exactly what this building complex used to be. In the past, you see, there were commercial livestock pens and slaughterhouses in the city center. But as the city grew, it was decided that this was both inadequate and unhygienic. Thus it was decided to build a large municipal slaughterhouse in what was then the outskirts of the city. After a lengthy planning period, and over a decade of construction, the Madrid Matadero opened in 1925.

The Matadero is a complex of nearly identical buildings connected by walkways and courtyards. Each building was originally for a different purpose. Some were pens to hold living animals, others were for the act of killing. Some were for cattle, others for pigs, and others for chickens. And of course there were processing facilities, too, where the meat was broken down, divided, salted, preserved, boiled, and so on. One can only imagine the stench.
Much time and care was spent in making this facility both attractive and efficient. Yet the city quickly overtook the scope of the original design. As the Matadero got swallowed up in the expanding urban center, it was no longer isolated from the populace. What is more, a part of it had to be demolished to make way for the aforementioned M-30 highway, further limiting its use. Most of all, however, the facility was simply not big enough, nor modern enough, for the new Madrid. By the 1970s, the Matadero ceased its original function, and nobody was quite sure what to do with it.
Luckily, it was ultimately decided not to demolish these buildings, but to convert them into what they are today: a cultural center. It was an inspired choice, as the architecture of the Matadero is astoundingly lovely. Built in a neo-Mudéjar style—with bricks, stonework, and tiles—the buildings seem almost festive with their pointed roofs. One wonders why such a place was made to look so pretty, as it must have been nauseatingly grim while it served its original function. Now, however, it is positively inviting.

It is difficult to enumerate all of the things that the visitor can see and do at the Matadero. They have theater performances, both contemporary and classical, both inside and outdoors. There are photography and art exhibits; and the cultural center is the permanent headquarters of the National Dance Company. There is even a small movie theater showing artsy films. Added to this, the Matadero hosts various events throughout the year, from concerts to seasonal markets, from comic book conventions to ice skating rinks and theme park rides. With its bar and café, it is a remarkable resource for the madrileño looking for a bit of culture.

Next to the Matadero is an attractive group of yellow apartment buildings that surround a central courtyard. This is the Colonia del Pico del Pañuelo, built to provide affordable housing for the workers of the Matadero. Its name (“the point of a handkerchief”) comes from its form: from above, it looks like a folded piece of fabric. Made of reinforced concrete, the workers’ colony is nevertheless quite picturesque, and has been featured in several films. Nowadays, however, it is not quite so affordable.
I also want to mention another nearby attraction, the Crystal Palace of Arganzuela. This is a large greenhouse next to the Matadero. Free to visit, the greenhouse has four separate areas corresponding to different climatic zones. It adds a bit of natural wonder to the cultural attractions next door.

After discussing all of this history, and all of these landmarks, I fear that I am still not doing justice to the real charm of these places. The Madrid Río is, above all, a park—and a good one. Flat and scenic, it is ideal for a lazy bike ride or a long run—or just for sitting on a bench and watching the locals stroll by. There is a football field and a skate park, and several cafés and kiosks where the visitor can have a cold beer under the blue sky. The Matadero is special for being a cultural space that is primarily for the madrileños. One doesn’t have to wait in line with hordes of tourists here—and I hope it stays that way.
And the Madrid Río keeps going. If you follow the river south, you go through the Parque Lineal de Manzanares, an oddly futuristic park, where you can admire Manolo Valdés’ monumental statue of a woman’s head. Go further along the river, and the city is left behind completely. You find yourself in the arid countryside of central Castille, where storks nest in giant colonies and caves perforate the cliffs overhead. This is where I would go on my long runs, savoring the sliver of green that is the river, as it cuts through the yellow landscape. After an hour of running, the city would seem like a distant memory, somehow swallowed up in the shallow waters of the Manzanares.
