Ateneo La Maliciosa is an initiative driven towards all who want to support or participate in Madrid’s social life and who value political autonomy generated within grassroots organizations and collectives. Ateneo welcomes people and collectives form Madrid or elsewhere who need a space to develop activities, foster encounters, and build collectively. It is also intended for individuals and groups, from Madrid or outside the city, who need a space to carry out activities, meet, and build collectively. Those who organize Ateneo La Maliciosa are part of Madrid’s and Spain’s social movements. Four promoting groups come together to launch Ateneo La Maliciosa: Ecologistas en Acción, Ecologistas en Acción de Madrid, Fundación de los Comunes, and Traficantes de Sueños. The idea was activated in 2019, and, in 2022, the space was inaugurated and designed to host the initiatives and activities of those collectives, projects and people of this engaged environment. This project goes far beyond the sum of the promoting organizations. Ateneo La Maliciosa is a social space with its own life, which develops from the convergence of these and other collectives.
