This paper presents the experience of the Corporación para la Comunicación Ciudad Comuna and its work in the neighborhoods of the Commune 8 of Medellín during the 2012-2015 period. This is a representative case where the people from the local space, affected by the urban transformations, claimed themselves as subjects of rights and communicators that used different tools, such as: education, visual and written reporting, social video, and other actions, in order to show other ways of conceiving a dignified life in the marginal neighborhoods, and dispute the senses of rights. The study concludes that, through a critical exercise of community communication and its potential as a transformative power, common senses were created on an emancipatory rationality of the rights, where the subjects from the Commune claimed the city, territory, memory, and peace, as the fundamental rights to live with dignity in the marginal neighborhoods.
