Altera APS is a cultural association founded in 2001 from the collaboration of workers, students and teachers of Turin and its nearby areas, with the purpose to understand and critically discuss the political, cultural, artistic and social changes of the society in which we live. Since 2006, Altera has been registered in Arci in the Turin Territorial Committee and belongs to the network UCCA (Unione dei Circoli Cinematografici dell'Arci). Since 2015 Altera joins the newly born network of associations Casa Arcobaleno, which brings together about 20 associations from Turin engaged in human rights and defense of minorities within a cultural space in the Porta Palazzo neighborhood, strongly characterized by migrant communities. Altera operates in the field of cultural promotion and action, stimulating new forms of participation and active citizenship, pursuing an ethic of confrontation, civil coexistence and the principles of democratic legality.
