Situated on a concrete wall outside the MACBA, this huge 30m mural is the creation of artist Keith Harring. He drew the blood-red lines with characteristic figures to draw attention to AIDS, a disease he was diagnosed with shortly after putting this up. Known for using public places to bring important taboo topics to the forefront, he chose the Raval to execute his message deliberately. During the late 80s, when he created this emblematic work, the Raval used to one of the most derelict areas, with drugs and prostitution at its peak. Harring chose to create this very personal and public mural right in the centre of the Raval to serve as a cautionary message to the local youth. This is actually a replica, and if you’re keen to find out more about the original, head to the Filmoteca de Catalunya, a film archive in Salvador Seguí square.
