This research aims to analyze the construction of means for the reappropriation and collective management of public space in the city of Rio de Janeiro through the Opavivará! art collective. The Opavivará! group, created in 2003 by artists from Rio de Janeiro, is an art collective that carries out actions in public locations of the city, galleries, and cultural institutions, proposing inversions of the modes of urban space occupation through the creation of relational devices that suggest collective experiences, actively participating in the panorama of contemporary arts. Opavivará! is a cry for free and critical art. The group specifically produces art that aims to explore non-institutionalized contexts of aesthetic interest and propose a strategy of space occupation. Faced with the strategic and market-driven rationality of hegemonic territorial ordering, the process of social segregation based on private property ownership has become a general trend in cities. And public space, inserted into this logic of privatization, becomes a space where contemporary transformations of the city take place in tune with the dominant order. These changes are led by agents who question the imperatives of the neoliberal State by claiming the right to use and occupy the city autonomously. From this perspective, in recent years, there has been a multiplication of attempts at collective management of public space in Rio de Janeiro through public art. New artistic groups, such as Opavivará!, are initiatives that show multiple alternatives and possibilities for urban life.
