Santiago Sierra: world's largest graffiti | Locative Media | Scoop.it
In October 2012 the letters “S.O.S.” were carved into the ground of Western Sahara/Algeria near the Saharaui refugee camp Smara in collaboration with Artifariti and the Frente Polisario. The graffiti measures 5 km x 1,7 km, which makes it the largest graffiti in the world. The piece refers to the Saharaui peoples struggle for independence from Moroccan rule in the almost forgotten West Saharan conflict.
