The exhibition Puertas is a traveling exhibition that arrived in Madrid in February 2015. In it, the dominant development model is directly related to the situation of poverty and inequality suffered by 1 in 5 people in the world. Thus, visitors to the exhibition will find doors that, when they are closed, hide problems such as the conditions imposed on the poorest countries to receive aid, or the power operated by large energy companies, among many others. In coordination with CentroCentro Cibeles we communicate the project to the general press (monthly, newspapers, agencies, digital, radios …) and to specialized media in the world of poverty and solidarity. We also collaborate with media such as Eldiario.es or Planeta Futuro, from El País. As this is an extended time exhibition, we have also used social networks: In them we publicised the interactive nature of the exhibition and its educational opportunities for viewers of all ages.
