Despite the prophecies of secularization, the public expressions of religiosity in urban spaces keep a high presence in post-secular societies. According Jürgen Habermas (2008, 2009), “postsecular society” can be defined as the continuity of the religious expressions in a highly secularized milieu. As a part of a larger project (“The place of religion in open urban spaces: a comparative case study of public religious acts and celebrations in Madrid and Barcelona”), our investigation focuses on the practices and expressions of religiosity of Catholics in Madrid, paying special attention to the newest forms of occupying the streets. In addition to the traditional repertoire of liturgical acts (masses, processions, etc.), contemporary Spanish Church and laics are developing new strategies to keep or even extent their presence in the public spaces, Christianizing the city and the news. These strategies include a wide variety of resources inspired on the repertoire of mobilization of the old and new social movements, like demonstrations, protests and performances, legal initiatives, online activism among others.For this paper, we will explore the spatial expression of these practices in Madrid. For that, first we will describe the map and the agenda of urban Catholic activists. Secondly, we will analyze the more noticeable characteristics of the general repertoire and, thirdly, we will point out the general lines of the fieldwork we are designing in order to understand the point of view of the social actors about the public presence of religiosity in urban and public spaces.
