Urban interventionism is the name for activist art practices that work directly in the city - its streets, facades, and public spaces - to disturb ordinary perception and provoke social attention. Rather than placing a monument or a gallery work, the interventionist edits the built environment itself: cutting buildings apart, projecting images onto facades, inserting absurd or symbolic gestures where passers-by cannot avoid them. The practice's history includes 1960s street agitators such as San Francisco's Diggers and Amsterdam's Provos, and it gathered force with the 'spatial turn' of the 1980s, when theorists began to see urban space not as a container for social processes but as a medium through which they unfold. Today its practitioners range from Daniel Buren and Gordon Matta-Clark to Krzysztof Wodiczko, Thomas Hirschhorn, Francis Alÿs, and Banksy.
