An Open Call for five temporary urban interventions has just been launched for Guimarães 2012 – European Capital of Culture. Performance Architecture is an international ideas competition curated by Pedro Gadanho. It will offer kick-start prizes of 12.000€ to promote the appropriation of controversial public spaces by city inhabitants. The competition invites multidisciplinary teams of artists, architects, designers, and others to reactivate performance art strategies and participative architectures within the urban realm. Members of the juri include Santiago Cirugeda, Didier Fiuza Faustino, A77, Raumlabor, and Office for Subversive Architecture. Proposals may be submitted online until the 6th January 2012.
