The text explores the centrality of the peripheries in the thinking of Pope Francis, who sees them as privileged vantage points for understanding the world and the Church. In “Evangelii gaudium,” Francis argues that the peripheries are places of inclusion and new evangelization, recalling the image of the New Jerusalem as a model of a just and welcoming city. Architects and urban planners are called to think of spaces that foster integration and recognition of the other. The suburbs become a laboratory for creativity and innovation, where new forms of solidarity and connection can be built. The text reflects on the fragilities and enormous potential of peripheries, beings that have just been born but can become the ideal place where a more just society can be built.
