The Invisible Graffiti Artists of Medellín: Urban Art Beyond Comuna 13

Introduction: The Myth of Comuna 13 vs. the Underground Scene

If you're looking for graffiti in Medellín, the first thing you'll be recommended is Comuna 13. And yes, the escalators, the giant colorful murals, and the tours with reggaeton music are a well-established tourist experience. But there's a problem: almost everything you see there is commissioned art, paid for by the Mayor's Office or by brands. Local artists call it "institutional graffiti." Behind that postcard facade, there exists an underground scene of creators who paint without permission, at night, in neighborhoods that don't even appear in travel guides. They are the invisible graffiti artists of Medellín, and their canvas is not the pretty wall of a viewpoint, but the cracked concrete of a nameless street.

In July 2026, while tourists crowd Comuna 13 for the Instagram photo, there are entire neighborhoods where art remains an act of resistance. This article is for travelers who want to see the real city, the one not in the brochures. We're going to discover where clandestine graffiti is born, what techniques the artists who risk a fine or a run-in with the police use, and how you can visit these places without being just another tourist getting in the way.

Secret Neighborhoods Where Art Is Born

Medellín has over 200 neighborhoods. Most travelers only know El Poblado, Laureles, and Comuna 13. But the real graffiti, the kind that doesn't ask for permission, is elsewhere. Here are three neighborhoods where the underground scene is strong, but almost no one visits them.

Buenos Aires: The Museum of Resistance

East of the city, Buenos Aires is a lower-middle-class neighborhood that was one of the hardest hit by violence during the 90s. Today, its narrow, steep streets are filled with graffiti that tells the story of the displaced, the disappeared, and the survivors. There are no 10-meter murals with flowers and butterflies. Here the art is raw: disfigured faces, broken letters, political messages sprayed on in two minutes. Local artists, who call themselves "Los Hijos de la Tierra" (The Children of the Earth), paint on the facades of abandoned houses and on the walls of public schools. If you walk along Carrera 14 with Calle 33, you'll find a collection of stencils that tell the neighborhood's story without filters.

Fun fact: in Buenos Aires there is a mural that is only fully visible from a specific angle, because it's painted on two walls that form a 90-degree angle. Locals call it "El Ángel de la Esquina" (The Angel of the Corner), and no one knows who made it. It appeared one morning in 2019 and no one has erased it since.

Robledo: The Laboratory of Codes

Robledo is a group of neighborhoods in the northwestern area of Medellín. Here, graffiti is not decorative: it's a code. Artists use symbols that only locals understand: a red X means the block is under surveillance; a blue circle indicates a drug den nearby; a broken white line marks a gang's territory. It's not art for tourists; it's a language of survival. But there is also room for experimentation. In the upper part of Robledo, near the Parque de la Iglesia, there is an alley that graffiti artists call "La Tiza" (The Chalk). There, since 2021, they gather every Saturday at 10 PM to paint with recycled aerosols. They don't use sketches; everything is improvisation. If you arrive with respect and without a professional camera, they might let you watch. But be careful: don't take out your cell phone without asking.

La Sierra: The Art of the Periphery

La Sierra is one of the most stigmatized neighborhoods in Medellín. For years it was in the news for homicides and gang wars. But it's also where the collective "Grafiti Sin Fronteras" (Graffiti Without Borders) was born, which has been painting on the facades of houses in the highest part since 2015. Their murals don't have bright colors; they use earth tones, grays, and blacks. The message is simple: "We are alive." The artists of La Sierra don't sign their works. They don't want recognition; they want people to remember that behind every violence statistic, there is a family that is still there. If you want to see this art, you have to go with a local guide who knows the neighborhood. It's not safe to go alone, not because of the violence, but because the neighbors distrust strangers with cameras.

Forbidden Techniques: Political Stencils and Hidden Codes

Underground graffiti in Medellín is not limited to letters and colors. There are techniques that artists use to avoid being identified or to send messages that only certain eyes can read.

One-Pass Stencils

Stencils are quick to apply: the artist cuts a design into cardboard or plastic, tapes it to the wall, sprays the aerosol in two seconds, and runs off. In Medellín, political stencils are common. Since 2020, hundreds of silhouettes of women with raised fists have appeared, accompanied by the phrase "Ni una menos" (Not one less). There are also stencils criticizing the Mayor's Office, the police, or the transportation system. They don't last long, because the police erase them quickly, but new ones always appear. If you walk through downtown Medellín, on Calle 45 with Carrera 46, you'll see a collection of stencils that change every week. It's a game of cat and mouse.

Color Codes

In neighborhoods like Robledo and Manrique, graffiti artists use color codes to mark territory. Red and black usually belong to one gang; blue and white to another. But there are also more subtle codes. For example, a yellow triangle painted on the sidewalk means you can buy marijuana there. A green square indicates a bicycle workshop where you can take refuge if you have problems. These codes aren't written in any manual; they are learned on the street. For a tourist, it can be hard to decipher them, but if you see a symbol repeated several times on the same block, it's best not to stare for too long.

Reflective and UV Paint

Some artists experiment with paint that is only visible at night, under ultraviolet light. In the Boston neighborhood, near the University of Antioquia, there is a wall that looks gray during the day, but if you pass by with a UV flashlight, a huge face appears. It's the face of a social leader murdered in 2022. The artists painted it this way so the police wouldn't erase it during the day. It's an example of how graffiti adapts to repression.

Interview with Anonymous Artist (Pseudonym: "El Zorro")

We spoke with a graffiti artist who has been painting on the streets of Medellín for 12 years. He doesn't want to give his real name, but uses the pseudonym "El Zorro" (The Fox). We found him in a clandestine workshop in the upper part of Robledo, a room full of aerosols, empty cans, and sketches on newspaper.

Malokal: Why don't you paint in Comuna 13?

El Zorro: (Laughs) Because everything there is fake. They pay you to paint what they want. Butterflies, flowers, smiling children. That's not the reality of the neighborhood. The reality is that people are still displaced, young people have no jobs, the police are still killing. I paint what I see, not what the Mayor's Office wants tourists to see.

Malokal: What techniques do you use to avoid being caught?

El Zorro: It's all about timing. I paint between 2 and 4 in the morning. I only carry one aerosol, no more. If I see lights, I hide. Sometimes I wear gloves to avoid leaving fingerprints. But the most important thing is to have an escape plan. I always know where I'm going to run.

Malokal: What message do you want to leave with your art?

El Zorro: That Medellín is not just the city of fashion and entrepreneurship. It's a city that bleeds, that fights, that resists. My art is a scream. I don't want people to feel pretty when they see my murals. I want them to feel uncomfortable. To ask questions. To not forget.

Malokal: Any advice for tourists who want to see your work?

El Zorro: That they come with respect. Don't take photos without permission. Don't touch the walls. Don't leave trash. And above all, don't come with the attitude of "look how exotic." This isn't a zoo. It's my home.

How to Visit Ethically (Schedules, Unwritten Protocols)

Visiting Medellín's underground graffiti is not like going to a museum. There are unwritten rules you must follow to avoid getting into trouble or disrespecting the community.

Recommended Times

Most clandestine graffiti is painted at night, but it's not safe for a tourist to walk alone in neighborhoods like Robledo or La Sierra after 8 PM. It's best to go between 9 AM and 4 PM, when there are more people around and neighbors are out on the street. If you want to see the art in action, ask at community workshops. Some collectives, like "Grafiti Sin Fronteras" in La Sierra, organize painting sessions on Saturday mornings, open to the public who want to help.

Unwritten Protocols

• Don't photograph the artists without asking. Many don't want to be identified for safety reasons. If you insist, they might ask you to delete the photo.
• Don't touch the walls. Fresh paint can be ruined, and some murals have layers of years that the artists care for.
• Don't leave trash. In neighborhoods like Buenos Aires, locals associate tourists with dirt. Bring a bag for your waste.
• Don't make comments about the violence. Saying "how dangerous" or "how sad" is offensive to the people who live there. Instead, ask about daily life.
• If you see a symbol you don't understand, don't investigate it. Some codes belong to gangs. Asking can be interpreted as a threat.

Recommended Local Guides

There are no official tours for this type of art, but there are independent guides who work with collectives. Look for "Grafiti Sin Fronteras" or "Colectivo La Tiza" on social media. They sometimes offer free walks on weekends. If you can't find them, you can contact the Corporación Cultural de Buenos Aires, which has a "memory routes" program that includes political graffiti. Prices are voluntary, but a contribution of between 20,000 and 40,000 COP per person is appreciated.

Local Tips

• Wear comfortable shoes. Medellín's neighborhoods are steep. You'll be walking a lot, and the streets can be in poor condition.
• Dress discreetly. No bright colors, brand logos, or cameras hanging around your neck. Dress like a local: jeans, dark t-shirt, cap.
• Carry cash. In neighborhoods like Robledo and La Sierra, card machines are not common. You'll need small bills to buy water or a soda at a corner store.
• Learn some Spanish phrases. "Buenos días" (Good morning), "gracias" (thank you), and "permiso" (excuse me) open doors. Don't assume everyone speaks English.
• Don't use your cell phone on the street. Taking out your phone to look at the map makes you an easy target for thieves. Better to memorize the route or use a printed map.
• Respect siesta hours. Between 1 PM and 3 PM, many neighborhoods fall silent. Don't make noise or play music.

Frequently Asked Questions

Is it safe to visit neighborhoods like Robledo or La Sierra?

It depends on how you go. If you go alone, at night, and with a professional camera, it's not safe. But if you go during the day, accompanied by a local guide, and with a respectful attitude, the risk is low. These neighborhoods are not war zones; they are communities with problems, like any working-class neighborhood in Latin America. The most important thing is not to draw attention and not to do anything that could be interpreted as a provocation.

Can I buy aerosols or painting materials?

Yes, but don't expect to find specialized stores. In downtown Medellín, on Calle 45 with Carrera 47, there are hardware stores that sell generic aerosols for about 5,000 COP each. Underground artists usually buy at the Plaza Minorista, where there are stalls selling imported contraband paint. If you want to paint legally, look for a community workshop that will lend you materials in exchange for a donation.

How can I support the artists without exploiting them?

The best way is to buy their works directly. Many graffiti artists sell small canvases or prints of their designs. Ask the collectives if they have an online store or if they accept commissions. You can also donate aerosols, gloves, or masks to the workshops. Avoid giving cash to artists on the street, as it can put them at risk of being robbed. And above all, share their work on social media, giving them credit, not just a photo of the mural without a name.

Do you dare to discover the B-side of Medellín graffiti? Wear comfortable shoes and a discreet attitude. The invisible art is waiting for you on the corners that no one looks at.

How to Get There and Transportation

To explore Medellín's graffiti beyond Comuna 13, consider the following transportation options and routes to get around the city. Each neighborhood has its own artistic expression, and often, the best murals are in places that are not so touristy.

Public Transportation

Medellín's metro system is one of the best ways to get around. Connected to the integrated system's buses, you can easily reach neighborhoods like Poblado, Laureles, and Envigado, where there are also high-quality murals. Make sure to have your Cívica card loaded to avoid any issues.

MetroCable
