This eTwinning project accompanies an Erasmus+ partnership named "COME!" which is a co-operation of four European schools: Colexio Compañía de María in Santiago de Compostela, Spoleczne Gimnazjum Hispaniola in Warsaw, Collège Wilbur Wright in Champagné and Gymnasium Bad Nenndorf as the co-ordinating school. "COME"'s overall aim is to examine the extent to which mobility has shaped the lives and the life-styles of people in the four participating nations.
