This paper makes a discourse analysis of the Civic Ordinance of Barcelona, adopted by the City Hall of Barcelona- Spain in January of 2006, in order to typify and manage behaviour in the public spaces of the city. The textual corpus we used for this analysis is the Ordinance project in its two versions. The Discourse Analysis methodology used in this study has been proposed by different authors in this field (Martín Rojo, 2001; Parker, 1992; Potter & Wetherell, 1987; Van Dijk, 2003; Wetherell, 2001). Results point to the emergence of two kinds of discourses inside the text, as well as the strategies from which both discourses allow the construction of citizens' identities as a new way of governability in the spaces of contemporary European cities.
