Why does street art appear on buildings?

Street art often appears on buildings as a means of expression, transforming urban spaces into canvases that reflect social, political, or cultural messages. These public spaces allow artists to reach a wider audience and engage with the community. Additionally, abandoned or neglected buildings provide an opportunity for artists to beautify their surroundings and challenge the conventional notions of art being confined to galleries. The visibility and permanence of street art on buildings can also spark conversations and provoke thought within the public sphere.
