Keith Haring's Barcelona Mural, titled "Todos Juntos Podemos Parar el SIDA" (Together We Can Stop AIDS), was created in 1989 during his visit to the city. This mural was part of Haring's broader effort to raise awareness about AIDS and promote safe sex. It was painted in the Raval neighborhood, an area known at the time for its significant drug problems. The mural features many of Haring's iconic figures and symbols, including a giant red snake representing the threat of AIDS, dancing figures, and other elements that convey a message of hope and prevention (Barcelona Metropolitan) (Haring) (Barcelona Lowdown).

The mural was completed in just five hours, a testament to Haring's efficiency and the urgency he felt about spreading his message. The original mural, painted on a concrete buttress in Plaça de Salvador Seguí, quickly deteriorated due to environmental factors and vandalism. Despite its initial state of disrepair, the mural's significance as a piece of social and political commentary remained strong (Barcelona Metropolitan) (Barcelona Lowdown).

In the mid-1990s, the mural was transferred to a new location to preserve Haring's work. The city of Barcelona, along with the Museu d'Art Contemporani de Barcelona (MACBA), undertook efforts to save the mural by creating a full-scale tracing and transferring it to a more protected outdoor wall near the museum. This process ensured that Haring's powerful message would continue to be accessible to the public. The mural has since been recreated multiple times, with the most recent version painted in 2014 to mark the 25th anniversary of the original (Barcelona Metropolitan) (Wikipedia) (MACBA Barcelona).

Haring's Barcelona Mural remains a vital part of his legacy, reflecting his commitment to using art as a tool for advocacy and education. It stands as a lasting reminder of the importance of AIDS awareness and the impact of Haring's work in promoting social change through art (Barcelona Metropolitan) (Haring).
