SOLROUTES, as a research project, is a relational immersion into the underworld of “migrant” illegalized movements towards, around and through Europe – what elsewhere we referred to with the image of an underground Europe crisscrossing, exceeding and defying European border regime or “borderland”. It therefore meshes together and confronts itself with two words, routes and solidarity, assuming the latter as the fuel or energy that enables and feeds the material constitution and conditions.
