Street Art and Social Change: How Murals Move Communities

Article Summary

What this article covers: The history of street art and social change, from Mexican muralism and New York subway graffiti to Black Lives Matter murals and the political walls of Belfast and Derry, with practical guidance on seeing it responsibly.

Who this is for: Travellers, art lovers and students who want to understand the messages behind the murals they walk past, and visitors planning a street art trip to Northern Ireland or further afield.

Key takeaway: Street art and social change go together when local people shape the message, and the link weakens when murals are used only to decorate a neighbourhood for developers or tourists.

Expert insight: “Standing in front of a gable wall in west Belfast, you realise the painting is a conversation the street has been having with itself for fifty years. The best way to read street art is to ask who painted it, who lives behind it and who decided it should stay.” , Ciaran Connolly, Founder of ConnollyCove

Quick facts:

• In 2015 the Germen Crew collective painted 209 houses in Las Palmitas, Pachuca, as a single mural covering about 20,000 square metres.
• A US appeals court upheld $6.75 million in damages in 2020 after a developer whitewashed 45 aerosol works at 5Pointz in New York.
• The Arts Council of Northern Ireland launched its Re-Imaging Communities programme in 2006 to replace paramilitary murals with community-led artwork.

Street art has shaped political debate on walls in Belfast, Mexico City, Minneapolis and Bethlehem, turning ordinary brickwork into a public noticeboard that anyone can read and nobody can switch off. A mural reaches people who would never enter a gallery, which is why activists, councils and developers all compete for the same walls. In Ireland the link between street art and social change is especially direct, because the murals of west Belfast and the Bogside in Derry recorded the Troubles as they happened and now record the peace process.

At ConnollyCove, the Ireland-based travel and culture platform founded by Ciaran Connolly, we have spent years documenting murals across Northern Ireland, from the Troubles murals of the Falls Road to the newer commissioned walls of the Cathedral Quarter. This guide to street art and social change explains how murals have worked as tools of protest, and what travellers should know before visiting the walls that carry its messages.

Defining Street Art and Social Change

Street art is visual art made in public places, usually outside galleries and often without permission, that speaks to the general public rather than to other artists. The connection between street art and social change comes from that audience, because a stencil on a railway bridge is seen by everyone who passes and the message enters everyday life in a way a museum exhibit rarely does.

Street Art, Graffiti and Commissioned Murals Compared

The three terms overlap, but they describe different intentions. Graffiti is built around stylised letters aimed mainly at other writers, while street art borrows its outdoor canvas but relies on images and slogans that a passer-by can read at a glance. Commissioned murals sit at the institutional end, paid for by councils, community groups or businesses and painted with permission.

Criteria	Graffiti	Street Art	Commissioned Mural	Best Use for Readers
Visual focus	Lettering and signatures	Images, symbols, slogans	Narrative scenes, portraits	Use street art to read protest messages
Main audience	Other writers	The general public	Residents and visitors	Use murals to understand local identity
Legal status	Usually unsanctioned	Unsanctioned or tolerated	Fully permitted	Check status before photographing or touching
Typical purpose	Identity and territory	Critique, satire, debate	Civic pride, regeneration	Ask who paid for a mural before judging its message

Why Transience Gives Street Art Its Force

Most street art is expected to disappear, since rain loosens paste-ups and council crews clean walls, so a piece may last weeks rather than decades. Artists working on street art and social change often accept this, and when owners cut a piece out of a wall and send it to auction, they remove it from the street that gave it meaning, which is one reason those removals cause so much anger locally.

The Origins of Street Art

The history of street art and social change is longer than the spray-can image suggests, and the earliest roots are in state-funded murals rather than illegal tagging. Understanding these origins explains why the same wall can be read as protest, vandalism or civic decoration depending on who painted it.

Mexican Muralism and the Political Wall

After the Mexican Revolution, the government of the 1920s commissioned artists including Diego Rivera, José Clemente Orozco and David Alfaro Siqueiros to paint public buildings with scenes of national history, labour and inequality. The aim was to teach a largely illiterate population about its own past, and that idea of the wall as a public classroom still sits behind most community street art, and it is why Mexico remains one of the most important countries for anyone studying street art and social change.

From New York Subways to Paris Stencils

Modern graffiti writing took shape in Philadelphia in the late 1960s and spread through New York’s subway system in the 1970s, where writers covered entire carriages that carried their names across the city. In Paris in the early 1980s, Blek le Rat began spraying stencilled rats and figures on city walls, a technique that let artists produce detailed images quickly and later influenced Banksy. During the 1980s New York spent heavily on removing subway graffiti, which turned the art form into an argument about who controls public space.

Street Art Moves From Vandalism to Commission

From the 1990s onwards, cities began commissioning murals and auction houses started selling work by artists who had once been arrested for it. When Banksy’s Love is in the Bin sold at Sotheby’s in London in 2021 for more than £18.5 million, it confirmed that street art had become a valuable commodity as well as a form of protest, and that tension now runs through every debate about street art and social change.

Street Art as a Voice for Communities

Street art gives communities a way to describe their own problems and hopes in public, often when local newspapers and politicians are not listening. The most effective examples of street art and social change involve residents in choosing the message, which is the difference between a wall that changes a neighbourhood and one that simply decorates it.

Uniting Neglected Neighbourhoods

In Las Palmitas, a hillside district of Pachuca in central Mexico, the Germen Crew collective worked with residents for 14 months to paint 209 houses as a single swirling mural. Guinness World Records lists it as the record for most walls covered by one mural, with 452 families affected. The collective held workshops and asked families which colours they wanted, and young people from the area joined the painting teams. Officials credited it with a calmer neighbourhood, although that claim came from the government that funded it.

Artists as Activists for Social Issues

Many stories of street art and social change start with a single unsanctioned wall. In 1986 Keith Haring painted Crack is Wack on a handball court beside Harlem River Drive in New York without permission, as a warning about the drug epidemic affecting the city. He was fined, yet the city later restored and protected the mural. Artists have since used the same approach to address climate change and housing.

In Bogotá, Colombia, the 2011 police shooting of Diego Felipe Becerra, a 16-year-old graffiti artist, prompted public protest, and the city later introduced rules allowing graffiti on many surfaces. Bogotá is now known for its walking tours, and guides there often begin with that story.

Prominent Murals and Their Messages

Some of the best-known examples of street art and social change are murals that captured a moment people around the world were already discussing. The examples below show how a single painted wall can turn local grief or anger into a shared reference point.

George Floyd Mural and the Fight for Racial Justice

Days after George Floyd was killed by a police officer in Minneapolis in May 2020, artists including Xena Goldman, Cadex Herrera and Greta McLain painted a large portrait of him outside the shop at 38th Street and Chicago Avenue where he died. The intersection became a memorial and protest site, and images of the mural were shared worldwide as the Black Lives Matter protests spread. Artists in many other cities soon painted their own tributes.

Banksy’s Political Statements

Banksy, an anonymous British artist who began in Bristol, uses satire to criticise war, surveillance and consumerism. In 2005 he painted a series of images on the West Bank separation barrier near Bethlehem, including a girl floating over the wall with balloons. In Bristol in 2006, a large majority voted in a council poll to keep his Well Hung Lover on a council-owned wall.

The Berlin Wall and the East Side Gallery

Artists such as Thierry Noir painted the western face of the Berlin Wall during the 1980s. After the wall fell, more than 100 artists from 21 countries painted a 1.3-kilometre stretch in 1990, now preserved as the East Side Gallery.

Street Art and Social Change in Northern Ireland

Northern Ireland offers one of the clearest cases of street art and social change anywhere, with murals that recorded conflict and then helped communities move past it. Political murals have appeared on gable walls since the early twentieth century, and during the Troubles they became, in the words of researchers Andrew Hill and Andrew White, one of the best-known examples of political art in the world.

Belfast and Derry Murals From the Troubles to the Peace Process

Republican and loyalist communities used murals to mark territory and commemorate their dead. In Derry, the “You Are Now Entering Free Derry” slogan painted in 1969 became the starting point for the Bogside murals that now line Rossville Street, painted by the Bogside Artists to tell the story of the civil rights era. In Belfast, the political walls of the city carry messages about causes far beyond Ireland, from Palestine to Catalonia.

“The murals on the Falls and the Shankill were painted to be read by neighbours, and that is still how you should approach them as a visitor. Take a local guide from each community if you can, because the same wall will be explained in two very different ways, and both explanations are part of the story.” , Ciaran Connolly, Founder of ConnollyCove

Re-Imaging Communities and Its Critics

In 2006 the Arts Council of Northern Ireland launched the Re-Imaging Communities programme, funding local groups to replace paramilitary murals, flags and sectarian graffiti with imagery chosen by residents. Many images of hooded gunmen were replaced with local history and sporting heroes, and the programme also drew criticism. Ulster University sociologist Bill Rolston, who spent decades documenting the murals, argued that funding bodies avoided supporting work seen as oppositional, which raises a fair question about whether public money should decide what a community is allowed to say on its own walls.

Where to See Street Art in Belfast Today

Belfast’s newer street art is centred on the Cathedral Quarter, where commissioned walls cover the lanes around Hill Street. Our guide to street art in the Cathedral Quarter maps the main pieces, and the wider street art scene across Ireland includes festivals such as Waterford Walls. A walk from the Cathedral Quarter to the Falls Road in one afternoon shows the full range of street art and social change in the city, from playful commissioned pieces to murals that still carry the weight of the conflict.

Street Art, Law Enforcement and Vandalism

The legal status of street art depends on where it is painted, who owns the wall and whether permission was given. In England and Wales, painting a wall without consent falls under the Criminal Damage Act 1971, and Northern Ireland has an equivalent offence under the Criminal Damage (Northern Ireland) Order 1977, so unsanctioned work remains a crime however well it is received.

Graffiti and Public Perception

Graffiti has long been treated as a sign of neighbourhood decline, and many police forces still link tagging with antisocial behaviour. Public opinion has softened towards pictorial work, and the same council that removes tags one week may protect a stencil the next if residents value it, so the line between vandalism and public art is often drawn after the paint has dried.

Who Owns a Street Art Mural

Ownership becomes complicated when a piece becomes valuable. In The Creative Foundation v Dreamland Leisure Ltd (2015), the High Court in London ruled that a Banksy mural removed from a wall in Folkestone by a tenant belonged to the landlord, and ordered its return. In the United States, artists at the 5Pointz warehouse complex in New York sued after the owner whitewashed their work in November 2013, and the appeals court upheld $6.75 million in damages under the Visual Artists Rights Act in 2020. UK law gives artists copyright in original work automatically, but there is no direct equivalent of the American protection against destruction, so a UK owner can usually paint over a mural on their own property.

When Street Art Becomes Artwashing

Artwashing describes the use of street art to make a neighbourhood look creative and attractive to investors, often shortly before rents rise and long-standing residents are priced out. It is the strongest criticism of the link between street art and social change, because the same murals that once challenged power can end up helping developers sell flats.

The Wynwood district of Miami is the most cited example, where property developer Tony Goldman opened Wynwood Walls in 2009 and the area became a visitor attraction with sharply rising property values. A practical test for readers is to ask who commissioned a mural and whether residents were consulted.

Street Art Beyond the Western Lens

Outside Europe and North America, street art and social change take different forms and carry different risks, and some of the most interesting work comes from cities that rarely appear in guidebooks. Artists there often work with less commercial support.

Influences and Movements in Africa and Latin America

In Dakar, Senegal, artists such as Docta have used walls to address public health, education and the environment, and the Festigraff festival has brought international artists to the city since 2010. In São Paulo, Brazil, the cryptic black lettering known as pixação covers tower blocks and is widely read as a protest against inequality by young people from the city’s outskirts, even though many residents regard it as vandalism. Our wider guide to street murals around the world covers more of these cities in detail.

The Digitalisation of Street Art

Social media has changed the relationship between street art and social change, because a mural painted overnight can be shared thousands of times before breakfast, which is how the George Floyd tributes spread between continents within days. The downside is that some walls are now painted mainly to be photographed, drawing crowds to residential streets.

How to Experience Street Art Responsibly

Travellers interested in street art and social change can see the walls without disrespecting the communities that live with them, and a few habits make a real difference. The aim is to treat a mural district as someone’s home rather than an open-air attraction.

Start by booking a local guide, ideally someone who lives in the area or works for a community organisation, because they can explain the history behind each wall and the money stays in the neighbourhood. In Belfast, that means considering separate guides for the Falls Road and the Shankill Road. Avoid touching existing works, photograph residents only with their agreement and spend money in local cafés. Memorial murals deserve the same respect as a graveside, so read up on an area’s history before you visit.
